Background: Meniscal and chondral damage is common in the patient undergoing revision anterior cruciate ligament (ACL) reconstruction., Purpose: To determine if meniscal and/or articular cartilage pathology at the time of revision ACL surgery significantly influences a patient's outcome at 6-year follow-up., Study Design: Cohort study; Level of evidence, 3., Methods: Patients undergoing revision ACL reconstruction were prospectively enrolled between 2006 and 2011. Data collection included baseline demographics, surgical technique, pathology, treatment, and scores from 4 validated patient-reported outcome instruments: International Knee Documentation Committee (IKDC), Knee injury and Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Marx Activity Rating Scale. Patients were followed up at 6 years and asked to complete the identical set of outcome instruments. Regression analysis assessed the meniscal and articular cartilage pathology risk factors for clinical outcomes 6 years after revision ACL reconstruction., Results: An overall 1234 patients were enrolled (716 males, 58%; median age, 26 years). Surgeons reported the pathology at the time of revision surgery in the medial meniscus (45%), lateral meniscus (36%), medial femoral condyle (43%), lateral femoral condyle (29%), medial tibial plateau (11%), lateral tibial plateau (17%), patella (30%), and trochlea (21%). Six-year follow-up was obtained on 79% of the sample (980/1234). Meniscal pathology and articular cartilage pathology (medial femoral condyle, lateral femoral condyle, lateral tibial plateau, trochlea, and patella) were significant drivers of poorer patient-reported outcomes at 6 years (IKDC, KOOS, WOMAC, and Marx). The most consistent factors driving outcomes were having a medial meniscal excision (either before or at the time of revision surgery) and patellofemoral articular cartilage pathology. Six-year Marx activity levels were negatively affected by having either a repair/excision of the medial meniscus (odds ratio range, 1.45-1.72; P ≤ .04) or grade 3-4 patellar chondrosis (odds ratio, 1.72; P = .04). Meniscal pathology occurring before the index revision surgery negatively affected scores on all KOOS subscales except for sports/recreation ( P < .05). Articular cartilage pathology significantly impaired all KOOS subscale scores ( P < .05). Lower baseline outcome scores, higher body mass index, being a smoker, and incurring subsequent surgery all significantly increased the odds of reporting poorer clinical outcomes at 6 years., Conclusion: Meniscal and chondral pathology at the time of revision ACL reconstruction has continued significant detrimental effects on patient-reported outcomes at 6 years after revision surgery.

Purpose: To develop a standardized opioid prescribing schedule (SOPS) following anterior cruciate ligament reconstruction (ACLR) and rotator cuff repair (RCR) and evaluate postoperative opioid consumption alongside Patient-Reported Outcome Measurement Information System (PROMIS) pain interference scores., Methods: A prospective observational study was performed on all patients undergoing primary ACLR and RCR from March 2019 to October 2021. Patients taking opioids preoperatively and revision ACLR and RCR were excluded. PROMIS 6B questionnaires were administered before and after implantation of the SOPS initiated on December 15, 2019. Opioid consumption was determined by email surveys. Hypothesis testing was performed with Mann-Whitney U test., Results: A total of 599 patients met inclusion criteria with 188 patients (71 ACLR and 117 RCR) completing surveys. Before the initiation of SOPS, the average number of oxycodone 5-mg tablets prescribed for ACLR was 44.6 (95% confidence interval [CI] 42.4-46.9) and for RCR was 44.7 (95% CI 42.7-46.8). The average usage was 23.1 (95% CI 16.9-29.2) and 22.1 (95% CI 16.2-28.0), respectively. Following SOPS of 30 tablets of oxycodone 5 mg for ACLR and 40 tablets for RCR, the average number of tablets prescribed significantly decreased for both procedures ( P < .01 for ACLR and RCR), and the average consumption decreased to 20.5 (95% CI 16.6-24.4) and 18.6 (95% CI 14.6-22.5), respectively. PROMIS 6B responses did not demonstrate statistically significant changes following SOPS., Conclusions: The results of the present study demonstrate that the implementation of a SOPS reduced postoperative opioid prescribing amounts and consumption without significant impacting PROMIS pain interference scores for ACLR and RCR, supporting the possibility to decrease and standardize opioid prescribing following common sports medicine procedures., Level of Evidence: III: Retrospective, comparative, therapeutic study., (© 2022 The Authors.)

Background: Lytic or malpositioned tunnels may require bone grafting during revision anterior cruciate ligament reconstruction (rACLR) surgery. Patient characteristics and effects of grafting on outcomes after rACLR are not well described., Purpose: To describe preoperative characteristics, intraoperative findings, and 2-year outcomes for patients with rACLR undergoing bone grafting procedures compared with patients with rACLR without grafting., Study Design: Cohort study; Level of evidence, 3., Methods: A total of 1234 patients who underwent rACLR were prospectively enrolled between 2006 and 2011. Baseline revision and 2-year characteristics, surgical technique, pathology, treatment, and patient-reported outcome instruments (International Knee Documentation Committee [IKDC], Knee injury and Osteoarthritis Outcome Score [KOOS], Western Ontario and McMaster Universities Osteoarthritis Index, and Marx Activity Rating Scale [Marx]) were collected, as well as subsequent surgery information, if applicable. The chi-square and analysis of variance tests were used to compare group characteristics., Results: A total of 159 patients (13%) underwent tunnel grafting-64 (5%) patients underwent 1-stage and 95 (8%) underwent 2-stage grafting. Grafting was isolated to the femur in 31 (2.5%) patients, the tibia in 40 (3%) patients, and combined in 88 patients (7%). Baseline KOOS Quality of Life (QoL) and Marx activity scores were significantly lower in the 2-stage group compared with the no bone grafting group ( P ≤ .001). Patients who required 2-stage grafting had more previous ACLRs ( P < .001) and were less likely to have received a bone-patellar tendon-bone or a soft tissue autograft at primary ACLR procedure ( P ≤ .021) compared with the no bone grafting group. For current rACLR, patients undergoing either 1-stage or 2-stage bone grafting were more likely to receive a bone-patellar tendon-bone allograft ( P ≤ .008) and less likely to receive a soft tissue autograft ( P ≤ .003) compared with the no bone grafting group. At 2-year follow-up of 1052 (85%) patients, we found inferior outcomes in the 2-stage bone grafting group (IKDC score = 68; KOOS QoL score = 44; KOOS Sport/Recreation score = 65; and Marx activity score = 3) compared with the no bone grafting group (IKDC score = 77; KOOS QoL score = 63; KOOS Sport/Recreation score = 75; and Marx activity score = 7) ( P ≤ .01). The 1-stage bone graft group did not significantly differ compared with the no bone grafting group., Conclusion: Tunnel bone grafting was performed in 13% of our rACLR cohort, with 8% undergoing 2-stage surgery. Patients treated with 2-stage grafting had inferior baseline and 2-year patient-reported outcomes and activity levels compared with patients not undergoing bone grafting. Patients treated with 1-stage grafting had similar baseline and 2-year patient-reported outcomes and activity levels compared with patients not undergoing bone grafting.

Background: Patients with anterior cruciate ligament (ACL) revision report lower outcome scores on validated knee questionnaires postoperatively compared to cohorts with primary ACL reconstruction. In a previously active population, it is unclear if patient-reported outcomes (PROs) are associated with a return to activity (RTA) or vary by sports participation level (higher level vs. recreational athletes)., Hypotheses: Individual RTA would be associated with improved outcomes (ie, decreased knee symptoms, pain, function) as measured using validated PROs. Recreational participants would report lower PROs compared with higher level athletes and be less likely to RTA., Study Design: Cohort study; Level of evidence, 2., Methods: There were 862 patients who underwent a revision ACL reconstruction (rACLR) and self-reported physical activity at any level preoperatively. Those who did not RTA reported no activity 2 years after revision. Baseline data included patient characteristics, surgical history and characteristics, and PROs: International Knee Documentation Committee questionnaire, Marx Activity Rating Scale, Knee injury and Osteoarthritis Outcome Score, and the Western Ontario and McMaster Universities Osteoarthritis Index. A binary indicator was used to identify patients with same/better PROs versus worse outcomes compared with baseline, quantifying the magnitude of change in each direction, respectively. Multivariable regression models were used to evaluate risk factors for not returning to activity, the association of 2-year PROs after rACLR surgery by RTA status, and whether each PRO and RTA status differed by participation level., Results: At 2 years postoperatively, approximately 15% did not RTA, with current smokers (adjusted odds ratio [aOR] = 3.3; P = .001), female patients (aOR = 2.9; P < .001), recreational participants (aOR = 2.0; P = .016), and those with a previous medial meniscal excision (aOR = 1.9; P = .013) having higher odds of not returning. In multivariate models, not returning to activity was significantly associated with having worse PROs at 2 years; however, no clinically meaningful differences in PROs at 2 years were seen between participation levels., Conclusion: Recreational-level participants were twice as likely to not RTA compared with those participating at higher levels. Within a previously active cohort, no RTA was a significant predictor of lower PROs after rACLR. However, among patients who did RTA after rACLR, approximately 20% reported lower outcome scores. Most patients with rACLR who were active at baseline improved over time; however, patients who reported worse outcomes at 2 years had a clinically meaningful decline across all PROs.

Purpose: Anterior cruciate ligament rupture is associated with characteristic bone contusions in approximately 80% of patients, and these have been correlated with higher pain scores. Bone bruising may indicate joint damage that increases inflammation and the likelihood of posttraumatic osteoarthritis. We sought to characterize the severity of bone bruising following acute anterior cruciate ligament injury and determine if it correlates with synovial fluid and serum levels of the proinflammatory chemokine monocyte chemoattractant protein-1 associated with posttraumatic osteoarthritis., Methods: This was a retrospective analysis of data collected prospectively from January 2014 through December 2016. All patients who sustained an acute ligament rupture were evaluated within 15 days of injury, obtained a magnetic resonance imaging study, and underwent bone-patellar-tendon-bone autograft reconstruction were offered enrollment. The overall severity of bone bruising on magnetic resonance imaging was graded (sum of 0-3 grades in 13 sectors of the articular surfaces). Serum and synovial fluid levels of monocyte chemoattractant protein-1 were measured within 14 days of injury, and serum levels were again measured 6 and 12 months following surgery. Separate univariate linear regression models were constructed to determine the association between monocyte chemoattractant protein-1 and bone bruising severity at each time point., Results: Forty-eight subjects were included in this study. They had a mean age of 21.4 years and were 48% female. Median overall bone bruising severity was 5 (range 0-14). Severity of bone bruising correlated with higher synovial fluid concentrations of monocyte chemoattractant protein-1 preoperatively (R 2  = 0.18, p = 0.009) and with serum concentrations at 12 months post-reconstruction (R 2  = 0.12, p = 0.04)., Conclusions: The severity of bone bruising following anterior cruciate ligament rupture is associated with higher levels of the proinflammatory cytokine monocyte chemoattractant protein-1 in synovial fluid acutely post-injury and in serum 12-months following anterior cruciate ligament reconstruction. This suggests that severe bone bruising on magnetic resonance imaging after ligament rupture may indicate increased risk for persistent joint inflammation and posttraumatic osteoarthritis., Level of Evidence: III - retrospective cohort study., (© 2022.

Purpose: The purpose of this study was to determine the inter-rater reliability of arthroscopic video quality, determine correlation between surgeon rating and computational image metrics, and facilitate a quantitative methodology for assessing video quality., Methods: Five orthopaedic surgeons reviewed 60 clips from deidentified arthroscopic shoulder videos and rated each on a four-point Likert scale from poor to excellent view. The videos were randomized, and the process was completed a total of three times. Each user rating was averaged to provide a user rating per clip. Each video frame was processed to calculate brightness, local contrast, redness (used to represent bleeding), and image entropy. Each metric was then averaged over each frame per video clip, providing four image quality metrics per clip., Results: Inter-rater reliability for grading video quality had an intraclass correlation of .974. Improved image quality rating was positively correlated with increased entropy (.8142; P < .001), contrast (.8013; P < .001), and brightness (.6120; P < .001), and negatively correlated with redness (-.8626; P < .001). A multiple linear regression model was calculated with the image metrics used as predictors for the image quality ranking, with an R-squared value of .775 and root mean square error of .42., Conclusions: Our study demonstrates strong inter-rater reliability between surgeons when describing image quality and strong correlations between image quality and the computed image metrics. A model based on these metrics enables automatic quantification of image quality., Clinical Relevance: Video quality during arthroscopic cases can impact the ease and duration of the case which could contribute to swelling and complication risk. This pilot study provides a quantitative method to assess video quality. Future works can objectively determine factors that affect visualization during arthroscopy and identify options for improvement., (© 2021 The Authors.)

Background: Although graft choice may be limited in the revision setting based on previously used grafts, most surgeons believe that graft choice for anterior cruciate ligament (ACL) reconstruction is an important factor related to outcome., Hypothesis: In the ACL revision setting, there would be no difference between autograft and allograft in rerupture rate and patient-reported outcomes (PROs) at 6-year follow-up., Study Design: Cohort study; Level of evidence, 2., Methods: Patients who had revision surgery were identified and prospectively enrolled in this cohort study by 83 surgeons over 52 sites. Data collected included baseline characteristics, surgical technique and pathology, and a series of validated PRO measures. Patients were followed up at 6 years and asked to complete the identical set of PRO instruments. Incidence of additional surgery and reoperation because of graft failure were also recorded. Multivariable regression models were used to determine the predictors (risk factors) of PROs, graft rerupture, and reoperation at 6 years after revision surgery., Results: A total of 1234 patients including 716 (58%) men were enrolled. A total of 325 (26%) underwent revision using a bone-patellar tendon-bone (BTB) autograft; 251 (20%), soft tissue autograft; 289 (23%), BTB allograft; 302 (25%), soft tissue allograft; and 67 (5%), other graft. Questionnaires and telephone follow-up for subsequent surgery information were obtained for 809 (66%) patients, while telephone follow-up was only obtained for an additional 128 patients for the total follow-up on 949 (77%) patients. Graft choice was a significant predictor of 6-year Marx Activity Rating Scale scores ( P = .024). Specifically, patients who received a BTB autograft for revision reconstruction had higher activity levels than did patients who received a BTB allograft (odds ratio [OR], 1.92; 95% CI, 1.25-2.94). Graft rerupture was reported in 5.8% (55/949) of patients by their 6-year follow-up: 3.5% (16/455) of patients with autografts and 8.4% (37/441) of patients with allografts. Use of a BTB autograft for revision resulted in patients being 4.2 times less likely to sustain a subsequent graft rupture than if a BTB allograft were utilized ( P = .011; 95% CI, 1.56-11.27). No significant differences were found in graft rerupture rates between BTB autograft and soft tissue autografts ( P = .87) or between BTB autografts and soft tissue allografts ( P = .36). Use of an autograft was found to be a significant predictor of having fewer reoperations within 6 years compared with using an allograft ( P = .010; OR, 0.56; 95% CI, 0.36-0.87)., Conclusion: BTB and soft tissue autografts had a decreased risk in graft rerupture compared with BTB allografts. BTB autografts were associated with higher activity level than were BTB allografts at 6 years after revision reconstruction. Surgeons and patients should consider this information when choosing a graft for revision ACL reconstruction.

Infection is a rare occurrence after revision anterior cruciate ligament reconstruction (rACLR). Because of the low rates of infection, it has been difficult to identify risk factors for infection in this patient population. The purpose of this study was to report the rate of infection following rACLR and assess whether infection is associated with patient- and surgeon-dependent risk factors. We reviewed two large prospective cohorts to identify patients with postoperative infections following rACLR. Age, sex, body mass index (BMI), smoking status, history of diabetes, and graft choice were recorded for each patient. The association of these factors with postoperative infection following rACLR was assessed. There were 1423 rACLR cases in the combined cohort, with 9 (0.6%) reporting postoperative infections. Allografts had a higher risk of infection than autografts (odds ratio, 6.8; 95% CI, 0.9-54.5; p = .045). Diabetes (odds ratio, 28.6; 95% CI, 5.5-149.9; p = .004) was a risk factor for infection. Patient age, sex, BMI, and smoking status were not associated with risk of infection after rACLR., (© 2020 Orthopaedic Research Society. Published by Wiley Periodicals LLC.)

Background: Meniscal preservation has been demonstrated to contribute to long-term knee health. This has been a successful intervention in patients with isolated tears and tears associated with anterior cruciate ligament (ACL) reconstruction. However, the results of meniscal repair in the setting of revision ACL reconstruction have not been documented., Purpose: To examine the prevalence and 2-year operative success rate of meniscal repairs in the revision ACL setting., Study Design: Case-control study; Level of evidence, 3., Methods: All cases of revision ACL reconstruction with concomitant meniscal repair from a multicenter group between 2006 and 2011 were selected. Two-year follow-up was obtained by phone and email to determine whether any subsequent surgery had occurred to either knee since the initial revision ACL reconstruction. If so, operative reports were obtained, whenever possible, to verify the pathologic condition and subsequent treatment., Results: In total, 218 patients (18%) from 1205 revision ACL reconstructions underwent concurrent meniscal repairs. There were 235 repairs performed: 153 medial, 48 lateral, and 17 medial and lateral. The majority of these repairs (n = 178; 76%) were performed with all-inside techniques. Two-year surgical follow-up was obtained on 90% (197/218) of the cohort. Overall, the meniscal repair failure rate was 8.6% (17/197) at 2 years. Of the 17 failures, 15 were medial (13 all-inside, 2 inside-out) and 2 were lateral (both all-inside). Four medial failures were treated in conjunction with a subsequent repeat revision ACL reconstruction., Conclusion: Meniscal repair in the revision ACL reconstruction setting does not have a high failure rate at 2-year follow-up. Failure rates for medial and lateral repairs were both <10% and consistent with success rates of primary ACL reconstruction meniscal repair. Medial tears underwent reoperation for failure at a significantly higher rate than lateral tears.

As health care reimbursement evolves, physicians will continue to be evaluated based on the quality of care that they provide. One measure of quality is based on patient satisfaction as reported through the Consumer Assessment of Healthcare Providers and Systems Survey (CAHPS). Although previous studies have explored expectations and their role in patient satisfaction, no studies have investigated the role of patient expectations for interventions in surgical specialty clinics. Patients (N=126) were given 2 surveys, a pre-visit and a post-visit questionnaire, with options based on the CAHPS survey. Patients were asked to select common orthopedic services that they expected to receive from their appointments, rate their physicians on Likert scales, and report the services that were actually provided. Patients who left with unmet expectations for interventions (45%) rated their physicians lower than patients who had all of their expectations met (9.0±1.4 vs 9.5± 0.8; P<.05). For most individual interventions, there was no difference in satisfaction between patients with met and unmet expectations. However, patients who expected surgery and did not have their expectations met rated their physician lower than patients whose expectations for surgery were met (9.0±1.3 vs 9.7±0.6; P<.05). No statistically significant difference was found in physician rating with increased numbers of unmet expectations, individual surgeon rating, perceptions of their providers, and wait time. This study reports that patient expectations for interventions, and particularly a recommendation for surgery, may alter a patient's reported satisfaction, particularly when surgical expectations are unmet.

Background: The incidence of various open shoulder procedures has changed over time. In addition, various fellowships provide overlapping training in open shoulder surgery. There is a lack of information regarding the relationship between surgeon training and open shoulder procedure type and incidence in early career orthopedic surgeons., Methods: The American Board of Orthopaedic Surgery Part-II database was queried from 2002 to 2016 for reported open shoulder procedures. The procedures were categorized as follows: arthroplasty, revision arthroplasty, open instability, trauma, and open rotator cuff. We evaluated procedure trends as well as their relationship to surgeon fellowship categorized by Sports, Shoulder/Elbow, Hand, Trauma, and "Other" fellowship as well as no fellowship training. We additionally evaluated complication data as it related to procedure, fellowship category, and volume., Results: Over the 2002-2016 study period, there were increasing cases of arthroplasty, revision arthroplasty, and trauma (P < .001). There were decreasing cases in open instability and open rotator cuff (P < .001). Those with Sports training reported the largest overall share of open shoulder cases. Those with Shoulder/Elbow training reported an increasing overall share of arthroplasty cases and higher per candidate case numbers. The percentage of early career orthopedic surgeons reporting 5 or more arthroplasty cases was highest among Shoulder/Elbow candidates (P < .001). Across all procedures, those without fellowship training were least likely to report a complication (odds ratio [OR], 0.76; 95% confidence interval, 0.67-0.86; P < .001). Shoulder/Elbow candidates were least likely to report an arthroplasty complication (OR, 0.84, P = .03) as was any surgeon reporting 5 or more arthroplasty cases (OR, 0.81; 95% confidence interval, 0.70-0.94; P = .006)., Conclusion: The type and incidence of open shoulder surgery procedures continues to change. Among early career surgeons, those with more specific shoulder training are now performing the majority of arthroplasty-related procedures, and early career volume inversely correlates with complications., (Copyright © 2020 Journal of Shoulder and Elbow Surgery Board of Trustees.

Introduction: The optimal treatment of patients with a displaced intracapsular femoral neck fracture remains controversial. We utilised a national database of Medicare patients to determine if there was any difference in complications and reoperation rate of patients undergoing total hip arthroplasty (THA) or hemiarthroplasty (HA) for femoral neck fractures., Methods: This study utilised the PearlDiver Patient Records Database, a national for-fee database of Medicare patient procedure and diagnosis records from 2005 to 2012. Outcome procedures and diagnoses including revision, dislocation, infection, and cardiovascular events that occurred during the study time period were also identified over the entire study period as well as 90 days and 2 years., Results: We identified 275,439 patients with femoral neck fractures who underwent HA and 26,017 patients who underwent THA, respectively. Patients undergoing HA had significantly lower rates ( p < 0.0001) of revision 2.48% versus 3.85% (OR = 0.633; 95% CI, 0.592-0.678), dislocation 1.76% versus 3.39% (0.512; 0.476-0.551), infection 3.44% versus 4.87% (0.694; 0.657-0.737). There was no statistical significant difference in 2-year cardiac morbidity ( p = 0.252). However, when controlling for age, patients 65-69 years showed no significant difference in infection or revision over the study period or at 2 years., Conclusions: In this study, patients who underwent THA for femoral neck fractures had a higher rate of dislocations, infections and increased rates of repeat surgery than those who underwent HA but this difference was not significant in patients 65-69 years. Hemiarthroplasty may result in fewer complications in older Medicare patients although this difference may not be present in younger Medicare patients.

Background: Patient-reported outcomes (PROs) are a valid measure of results after revision anterior cruciate ligament (ACL) reconstruction. Revision ACL reconstruction has been documented to have worse outcomes when compared with primary ACL reconstruction. Understanding positive and negative predictors of PROs will allow surgeons to modify and potentially improve outcome for patients., Purpose/hypothesis: The purpose was to describe PROs after revision ACL reconstruction and test the hypothesis that patient- and technique-specific variables are associated with these outcomes., Study Design: Cohort study; Level of evidence, 2., Methods: Patients undergoing revision ACL reconstruction were identified and prospectively enrolled by 83 surgeons over 52 sites. Data included baseline demographics, surgical technique and pathology, and a series of validated PRO instruments: International Knee Documentation Committee (IKDC), Knee injury and Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities Osteoarthritis Index, and Marx Activity Rating Scale. Patients were followed up at 2 years and asked to complete the identical set of outcome instruments. Multivariate regression models were used to control for a variety of demographic and surgical factors to determine the positive and negative predictors of PRO scores at 2 years after revision surgery., Results: A total of 1205 patients met the inclusion criteria and were successfully enrolled: 697 (58%) were male, with a median cohort age of 26 years. The median time since their most recent previous ACL reconstruction was 3.4 years. Two-year questionnaire follow-up was obtained from 989 patients (82%). The most significant positive predictors of 2-year IKDC scores were a high baseline IKDC score, high baseline Marx activity level, male sex, and having a longer time since the most recent previous ACL reconstruction, while negative predictors included having a lateral meniscectomy before the revision ACL reconstruction or having grade 3/4 chondrosis in either the trochlear groove or the medial tibial plateau at the time of the revision surgery. For KOOS, having a high baseline score and having a longer time between the most recent previous ACL reconstruction and revision surgery were significant positive predictors for having a better (ie, higher) 2-year KOOS, while having a lateral meniscectomy before the revision ACL reconstruction was a consistent predictor for having a significantly worse (ie, lower) 2-year KOOS. Statistically significant positive predictors for 2-year Marx activity levels included higher baseline Marx activity levels, younger age, male sex, and being a nonsmoker. Negative 2-year activity level predictors included having an allograft or a biologic enhancement at the time of revision surgery., Conclusion: PROs after revision ACL reconstruction are associated with a variety of patient- and surgeon-related variables. Understanding positive and negative predictors of PROs will allow surgeons to guide patient expectations as well as potentially improve outcomes.

Background: Anterior cruciate ligament (ACL) revision cohorts continually report lower outcome scores on validated knee questionnaires than primary ACL cohorts at similar time points after surgery. It is unclear how these outcomes are associated with physical activity after physician clearance for return to recreational or competitive sports after ACL revision surgery., Hypotheses: Participants who return to either multiple sports or a singular sport after revision ACL surgery will report decreased knee symptoms, increased activity level, and improved knee function as measured by validated patient-reported outcome measures (PROMs) and compared with no sports participation. Multisport participation as compared with singular sport participation will result in similar increased PROMs and activity level., Study Design: Cross-sectional study; Level of evidence, 3., Methods: A total of 1205 patients who underwent revision ACL reconstruction were enrolled by 83 surgeons at 52 clinical sites. At the time of revision, baseline data collected included the following: demographics, surgical characteristics, previous knee treatment and PROMs, the International Knee Documentation Committee (IKDC) questionnaire, Marx activity score, Knee injury and Osteoarthritis Outcome Score (KOOS), and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). A series of multivariate regression models were used to evaluate the association of IKDC, KOOS, WOMAC, and Marx Activity Rating Scale scores at 2 years after revision surgery by sports participation category, controlling for known significant covariates., Results: Two-year follow-up was obtained on 82% (986 of 1205) of the original cohort. Patients who reported not participating in sports after revision surgery had lower median PROMs both at baseline and at 2 years as compared with patients who participated in either a single sport or multiple sports. Significant differences were found in the change of scores among groups on the IKDC ( P < .0001), KOOS-Symptoms ( P = .01), KOOS-Sports and Recreation ( P = .04), and KOOS-Quality of Life ( P < .0001). Patients with no sports participation were 2.0 to 5.7 times more likely than multiple-sport participants to report significantly lower PROMs, depending on the specific outcome measure assessed, and 1.8 to 3.8 times more likely than single-sport participants (except for WOMAC-Stiffness, P = .18), after controlling for known covariates., Conclusion: Participation in either a single sport or multiple sports in the 2 years after ACL revision surgery was found to be significantly associated with higher PROMs across multiple validated self-reported assessment tools. During follow-up appointments, surgeons should continue to expect that patients who report returning to physical activity after surgery will self-report better functional outcomes, regardless of baseline activity levels.

Background: The occurrence of physiologic knee hyperextension (HE) in the revision anterior cruciate ligament reconstruction (ACLR) population and its effect on outcomes have yet to be reported. Hypothesis/Purpose: The prevalence of knee HE in revision ACLR and its effect on 2-year outcome were studied with the hypothesis that preoperative physiologic knee HE ≥5° is a risk factor for anterior cruciate ligament (ACL) graft rupture., Study Design: Cohort study; Level of evidence, 2., Methods: Patients undergoing revision ACLR were identified and prospectively enrolled between 2006 and 2011. Study inclusion criteria were patients undergoing single-bundle graft reconstructions. Patients were followed up at 2 years and asked to complete an identical set of outcome instruments (International Knee Documentation Committee, Knee injury and Osteoarthritis Outcome Score, WOMAC, and Marx Activity Rating Scale) as well as provide information regarding revision ACL graft failure. A regression model with graft failure as the dependent variable included age, sex, graft type at the time of the revision ACL surgery, and physiologic preoperative passive HE ≥5° (yes/no) to assess these as potential risk factors for clinical outcomes 2 years after revision ACLR., Results: Analyses included 1145 patients, for whom 2-year follow-up was attained for 91%. The median age was 26 years, with age being a continuous variable. Those below the median were grouped as "younger" and those above as "older" (age: interquartile range = 20, 35 years), and 42% of patients were female. There were 50% autografts, 48% allografts, and 2% that had a combination of autograft plus allograft. Passive knee HE ≥5° was present in 374 (33%) patients in the revision cohort, with 52% being female. Graft rupture at 2-year follow-up occurred in 34 cases in the entire cohort, of which 12 were in the HE ≥5° group (3.2% failure rate) and 22 in the non-HE group (2.9% failure rate). The median age of patients who failed was 19 years, as opposed to 26 years for those with intact grafts. Three variables in the regression model were significant predictors of graft failure: younger age (odds ratio [OR] = 3.6; 95% CI, 1.6-7.9; P = .002), use of allograft (OR = 3.3; 95% CI, 1.5-7.4; P = .003), and HE ≥5° (OR = 2.12; 95% CI, 1.1-4.7; P = .03)., Conclusion: This study revealed that preoperative physiologic passive knee HE ≥5° is present in one-third of patients who undergo revision ACLR. HE ≥5° was an independent significant predictor of graft failure after revision ACLR with a >2-fold OR of subsequent graft rupture in revision ACL surgery.

Background: Articular cartilage health is an important issue following anterior cruciate ligament (ACL) injury and primary ACL reconstruction. Factors present at the time of primary ACL reconstruction may influence the subsequent progression of articular cartilage damage., Hypothesis: Larger meniscus resection at primary ACL reconstruction, increased patient age, and increased body mass index (BMI) are associated with increased odds of worsened articular cartilage damage at the time of revision ACL reconstruction., Study Design: Case-control study; Level of evidence, 3., Methods: Subjects who had primary and revision data in the databases of the Multicenter Orthopaedics Outcomes Network (MOON) and Multicenter ACL Revision Study (MARS) were included. Reviewed data included chondral surface status at the time of primary and revision surgery, meniscus status at the time of primary reconstruction, primary reconstruction graft type, time from primary to revision ACL surgery, as well as demographics and Marx activity score at the time of revision. Significant progression of articular cartilage damage was defined in each compartment according to progression on the modified Outerbridge scale (increase ≥1 grade) or >25% enlargement in any area of damage. Logistic regression identified predictors of significant chondral surface change in each compartment from primary to revision surgery., Results: A total of 134 patients were included, with a median age of 19.5 years at revision surgery. Progression of articular cartilage damage was noted in 34 patients (25.4%) in the lateral compartment, 32 (23.9%) in the medial compartment, and 31 (23.1%) in the patellofemoral compartment. For the lateral compartment, patients who had >33% of the lateral meniscus excised at primary reconstruction had 16.9-times greater odds of progression of articular cartilage injury than those with an intact lateral meniscus ( P < .001). For the medial compartment, patients who had <33% of the medial meniscus excised at the time of the primary reconstruction had 4.8-times greater odds of progression of articular cartilage injury than those with an intact medial meniscus ( P = .02). Odds of significant chondral surface change increased by 5% in the lateral compartment and 6% in the medial compartment for each increased year of age ( P ≤ .02). For the patellofemoral compartment, the use of allograft in primary reconstruction was associated with a 15-fold increased odds of progression of articular cartilage damage relative to a patellar tendon autograft ( P < .001). Each 1-unit increase in BMI at the time of revision surgery was associated with a 10% increase in the odds of progression of articular cartilage damage ( P = .046) in the patellofemoral compartment., Conclusion: Excision of the medial and lateral meniscus at primary ACL reconstruction increases the odds of articular cartilage damage in the corresponding compartment at the time of revision ACL reconstruction. Increased age is a risk factor for deterioration of articular cartilage in both tibiofemoral compartments, while increased BMI and the use of allograft for primary ACL reconstruction are associated with an increased risk of progression in the patellofemoral compartment.

Background: Revision anterior cruciate ligament (ACL) reconstruction has been documented to have worse outcomes compared with primary ACL reconstruction., Hypothesis: Certain factors under the control of the surgeon at the time of revision surgery can both negatively and positively affect outcomes., Study Design: Case-control study; Level of evidence, 3., Methods: Patients undergoing revision ACL reconstruction were identified and prospectively enrolled between 2006 and 2011. Data collected included baseline demographics, intraoperative surgical technique and joint disorders, and a series of validated patient-reported outcome instruments (International Knee Documentation Committee [IKDC] subjective form, Knee Injury and Osteoarthritis Outcome Score [KOOS], Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC], and Marx activity rating scale) completed before surgery. Patients were followed up for 2 years and asked to complete an identical set of outcome instruments. Regression analysis was used to control for age, sex, body mass index (BMI), activity level, baseline outcome scores, revision number, time since last ACL reconstruction, and a variety of previous and current surgical variables to assess the surgical risk factors for clinical outcomes 2 years after revision ACL reconstruction., Results: A total of 1205 patients (697 male [58%]) met the inclusion criteria and were successfully enrolled. The median age was 26 years, and the median time since their last ACL reconstruction was 3.4 years. Two-year follow-up was obtained on 82% (989/1205). Both previous and current surgical factors were found to be significant contributors toward poorer clinical outcomes at 2 years. Having undergone previous arthrotomy (nonarthroscopic open approach) for ACL reconstruction compared with the 1-incision technique resulted in significantly poorer outcomes for the 2-year IKDC ( P = .037; odds ratio [OR], 2.43; 95% CI, 1.05-5.88) and KOOS pain, sports/recreation, and quality of life (QOL) subscales ( P ≤ .05; OR range, 2.38-4.35; 95% CI, 1.03-10.00). The use of a metal interference screw for current femoral fixation resulted in significantly better outcomes for the 2-year KOOS symptoms, pain, and QOL subscales ( P ≤ .05; OR range, 1.70-1.96; 95% CI, 1.00-3.33) as well as WOMAC stiffness subscale ( P = .041; OR, 1.75; 95% CI, 1.02-3.03). Not performing notchplasty at revision significantly improved 2-year outcomes for the IKDC ( P = .013; OR, 1.47; 95% CI, 1.08-1.99), KOOS activities of daily living (ADL) and QOL subscales ( P ≤ .04; OR range, 1.40-1.41; 95% CI, 1.03-1.93), and WOMAC stiffness and ADL subscales ( P ≤ .04; OR range, 1.41-1.49; 95% CI, 1.03-2.05). Factors before revision ACL reconstruction that increased the risk of poorer clinical outcomes at 2 years included lower baseline outcome scores, a lower Marx activity score at the time of revision, a higher BMI, female sex, and a shorter time since the patient's last ACL reconstruction. Prior femoral fixation, prior femoral tunnel aperture position, and knee flexion angle at the time of revision graft fixation were not found to affect 2-year outcomes in this revision cohort., Conclusion: There are certain surgical variables that the physician can control at the time of revision ACL reconstruction that can modify clinical outcomes at 2 years. Whenever possible, opting for an anteromedial portal or transtibial surgical exposure, choosing a metal interference screw for femoral fixation, and not performing notchplasty are associated with significantly better 2-year clinical outcomes.

Proximal humerus fractures in the elderly are increasing in frequency as the population ages. The purpose of this study was to investigate surgical and cost trends in the Medicare population. The PearlDiver database was queried using diagnosis codes to identify Medicare recipients with proximal humerus fractures from 2005 to 2012. Surgical trends, demographics, and charge/reimbursement data were analyzed. There were 750,426 proximal humerus fractures in Medicare recipients during the 8-year period. Eighty-five percent of the fractures were treated nonoperatively; however, the percentage of operative vs nonoperative management increased significantly over time for all fractures, isolated fractures, and fracture dislocations. Open reduction and internal fixation (ORIF) was the most common surgical treatment and remained constant. Reverse total shoulder arthroplasty (RTSA) increased by 406% and hemiarthroplasty (HEMI) decreased by 47%. Compared with younger patients, older patients were more likely to undergo HEMI or RTSA than to undergo ORIF for isolated fractures and fracture dislocations. Charges and reimbursements from Medicare increased over time. The charge to reimbursement gap increased from 87% in 2005 to 104% in 2012. Charges were higher for RTSA than for ORIF or HEMI. Nonoperative management was the treatment of choice for 85% of proximal humerus fractures in the elderly; however, there was a trend toward higher rates of surgery. The RTSA rate increased and the HEMI rate decreased, while ORIF remained constant. There was an increasing charge to reimbursement ratio for all procedure types.

Background: While revision anterior cruciate ligament reconstruction (ACLR) can be performed to restore knee stability and improve patient activity levels, outcomes after this surgery are reported to be inferior to those after primary ACLR. Further reoperations after revision ACLR can have an even more profound effect on patient satisfaction and outcomes. However, there is a current lack of information regarding the rate and risk factors for subsequent surgery after revision ACLR., Purpose: To report the rate of reoperations, procedures performed, and risk factors for a reoperation 2 years after revision ACLR., Study Design: Case-control study; Level of evidence, 3., Methods: A total of 1205 patients who underwent revision ACLR were enrolled in the Multicenter ACL Revision Study (MARS) between 2006 and 2011, composing the prospective cohort. Two-year questionnaire follow-up was obtained for 989 patients (82%), while telephone follow-up was obtained for 1112 patients (92%). If a patient reported having undergone subsequent surgery, operative reports detailing the subsequent procedure(s) were obtained and categorized. Multivariate regression analysis was performed to determine independent risk factors for a reoperation., Results: Of the 1112 patients included in the analysis, 122 patients (11%) underwent a total of 172 subsequent procedures on the ipsilateral knee at 2-year follow-up. Of the reoperations, 27% were meniscal procedures (69% meniscectomy, 26% repair), 19% were subsequent revision ACLR, 17% were cartilage procedures (61% chondroplasty, 17% microfracture, 13% mosaicplasty), 11% were hardware removal, and 9% were procedures for arthrofibrosis. Multivariate analysis revealed that patients aged <20 years had twice the odds of patients aged 20 to 29 years to undergo a reoperation. The use of an allograft at the time of revision ACLR (odds ratio [OR], 1.79; P = .007) was a significant predictor for reoperations at 2 years, while staged revision (bone grafting of tunnels before revision ACLR) (OR, 1.93; P = .052) did not reach significance. Patients with grade 4 cartilage damage seen during revision ACLR were 78% less likely to undergo subsequent operations within 2 years. Sex, body mass index, smoking history, Marx activity score, technique for femoral tunnel placement, and meniscal tearing or meniscal treatment at the time of revision ACLR showed no significant effect on the reoperation rate., Conclusion: There was a significant reoperation rate after revision ACLR at 2 years (11%), with meniscal procedures most commonly involved. Independent risk factors for subsequent surgery on the ipsilateral knee included age <20 years and the use of allograft tissue at the time of revision ACLR.

Purpose: To identify and quantify patient- and procedure-related risk factors for post-arthroscopic knee infections using a large dataset., Methods: An administrative health care database including 8 years of records from 2 large commercial insurers and Medicare (a 5% random sample) was queried to identify all knee arthroscopies performed on patients aged at least 15 years using Current Procedural Terminology (CPT) codes. Each CPT code was designated as a high- or low-complexity procedure, with the former typically requiring accessory incisions or increased operative time. Deep infections were identified by a CPT code for incision and drainage within 90 days of surgery. Superficial infections were identified by International Classification of Diseases, Ninth Revision infection codes without any record of incision and drainage. Patients were compared based on age, sex, body mass index, tobacco use, presence of diabetes, and Charlson Comorbidity Index., Results: A total of 526,537 patients underwent 595,083 arthroscopic knee procedures. Deep postoperative infections occurred at a rate of 0.22%. Superficial infections occurred at a rate of 0.29%. Tobacco use and morbid obesity were the largest risk factors for deep and superficial infections, respectively (P < .001; relative risk of 1.90 and 2.19, respectively). There were also higher infection rates among patients undergoing relatively high-complexity arthroscopies, men, obese patients, diabetic patients, and younger patients (in order of decreasing relative risk). Increased Charlson Comorbidity Index was associated with superficial and total infections (P < .001)., Conclusions: Post-arthroscopic knee infections were more frequent among morbidly obese patients, tobacco users, patients undergoing relatively complex procedures, men, obese patients, diabetic patients, relatively young patients, and patients with increased comorbidity burdens in this study population. This knowledge may allow more informed preoperative counseling, aid surgeons in patient selection, and facilitate infection prevention by targeting individuals with higher inherent risk., Level of Evidence: Level IV, cross-sectional study., (Copyright © 2016 Arthroscopy Association of North America.

Background: Rotator cuff tears have a lifetime incidence between 25% and 40% in the United States, but optimum treatment strategies and protocol have not yet been widely accepted. This study evaluated the proportions of patients treated with nonoperative and operative modalities and how this proportion has changed during an 8-year period (2005-2012) among patients with Medicare., Methods: Using the PearlDiver patient record database, we identified Medicare patients having been diagnosed with a rotator cuff tear. These patients were then stratified on the basis of treatment with physical therapy, subacromial/glenohumeral injection, or rotator cuff repair. We analyzed the data in regard to standard demographic information, comorbidities, and the Charlson Comorbidity Index., Results: During the study period, 878,049 patients were identified and 397,116 patients had rotator cuff repair. The proportion of patients treated initially with physical therapy dropped from 30.0% in 2005 to 13.2% in 2012, and the subacromial/glenohumeral injection proportion decreased from 6.00% to 4.19% (P < .001). The proportion of patients who had rotator cuff repair increased from 33.8% to 40.4% from 2005 to 2012 (P < .001). Charlson Comorbidity Indexes were significantly lower in operative patients compared with each nonoperative treatment examined., Discussion: This analysis demonstrates a significant decrease in the initial trial of nonoperative treatment and an increase in the rate of surgery. Patients undergoing rotator cuff repair had fewer comorbidities than those undergoing nonoperative treatments. It also demonstrates that patients who had a trial of injection had a higher incidence of eventual rotator cuff repair compared with the patients with an initial trial of physical therapy., (Copyright © 2016 Journal of Shoulder and Elbow Surgery Board of Trustees.

Purpose: To investigate rates, trends, and complications for carpal tunnel release (CTR) related to fellowship training using the American Board of Orthopaedic Surgery Part II Database., Methods: We searched the American Board of Orthopaedic Surgery database for patients with carpal tunnel syndrome who underwent either open carpal tunnel release (OCTR) or endoscopic (ECTR) from 2003 to 2013. Cases with multiple treatment codes were excluded. Data were gathered on geographic location, fellowship, and surgical outcomes. Data were then divided into 2 cohorts: hand fellowship trained versus non-hand fellowship trained. We performed analysis with chi-square tests of independence and for trend., Results: Overall, 12.4% of all CTRs were done endoscopically. Hand fellowship-trained orthopedists performed about 4.5 times the number of ECTR than did non-hand fellowship-trained surgeons. An increasing trend over time of ECTR was seen only among the hand fellowship cohort. The northwest region of the United States had the highest incidence (23.1%) of ECTR, and the Southwest the lowest incidence (5.9%). The complication incidence associated with CTR overall was 3.6%, without a significant difference between ECTR and OCTR. Within the hand fellowship cohort the complication incidence for ECTR was significantly less than for OCTR. There was no difference in overall complication rates with ECTR and OCTR between the 2 cohorts. Wound complications were higher with OCTR (1.2% vs 0.25%) and nerve palsy with ECTR (0.66% vs 0.27%); with postoperative pain equivalent between techniques independent of fellowship training., Conclusions: Within the United States from 2003 to 2013, the rate of ECTR increased, as did complications. However, complication rates remained low in the first 2 years of practice. Hand fellowship-trained surgeons performed more ECTR than did non-hand fellowship-trained orthopedic surgeons, and both groups had similar complication rates., Type of Study/level of Evidence: Therapeutic IV., (Copyright © 2016 American Society for Surgery of the Hand.

Background: Access to care is limited for patients with Medicaid with many conditions, but data investigating this relationship in the orthopaedic literature are limited. The purpose of this study was to investigate the relationship between health insurance status and access to care for a diverse group of adult orthopaedic patients, specifically if access to orthopaedic care is influenced by population density or distance from academic teaching hospitals., Methods: Two hundred and three orthopaedic practices within the state of North Carolina were randomly selected and were contacted on two different occasions separated by three weeks. An appointment was requested for a fictitious adult orthopaedic patient with a potential surgical problem. Injury scenarios included patients with acute rotator cuff tears, zone-II flexor tendon lacerations, and acute lumbar disc herniations. Insurance status was reported as Medicaid at the time of the first request and private insurance at the time of the second request. County population density and the distance from each practice to the nearest academic hospital were recorded., Results: Of the 203 practices, 119 (59%) offered the patient with Medicaid an appointment within two weeks, and 160 (79%) offered the patient with private insurance an appointment within this time period (p < 0.001). Practices in rural counties were more likely to offer patients with Medicaid an appointment as compared with practices in urban counties (odds ratio, 2.25 [95% confidence interval, 1.16 to 4.34]; p = 0.016). Practices more than sixty miles from academic hospitals were more likely to accept patients with Medicaid than practices closer to academic hospitals (odds ratio, 3.35 [95% confidence interval, 1.44 to 7.83]; p = 0.005)., Conclusions: Access to orthopaedic care was significantly decreased for patients with Medicaid. Practices in less populous areas were more likely to offer an appointment to patients with Medicaid than practices in more populous areas. Practices that were farther from academic hospitals were more likely to offer an appointment to patients with Medicaid than practices closer to academic hospitals., Clinical Relevance: This study illustrates the barriers to timely outpatient orthopaedic care that patients with Medicaid face. The findings from our study imply that patients with Medicaid in more populous areas and in areas closer to academic medical centers are less likely to obtain an outpatient orthopaedic appointment than patients with Medicaid in less populous areas and in areas more distant from academic medical centers. A shift in policy to enhance access to orthopaedic care for patients with Medicaid, especially those in urban areas and areas close to academic medical centers, will become increasingly important as more patients become eligible for Medicaid through the Patient Protection and Affordable Care Act of 2010., (Copyright © 2014 by The Journal of Bone and Joint Surgery, Incorporated.)

Background: After failure of nonoperative treatment, repair has long been the primary treatment option for symptomatic superior labrum anterior and posterior (SLAP) lesions of the shoulder. There is growing evidence to support both biceps tenotomy and tenodesis as effective alternative treatments for SLAP lesions., Hypotheses: For patients with isolated SLAP lesions, the frequency of SLAP repair has decreased, while treatment with biceps tenodesis and tenotomy has increased. Similar trends are expected in patients with SLAP lesions undergoing concomitant rotator cuff repair., Study Design: Cohort study; Level of evidence, 3., Methods: A query of the American Board of Orthopaedic Surgery part II database was performed from 2002 to 2011. The database was searched for patients with isolated SLAP lesions undergoing SLAP repair, open biceps tenodesis, arthroscopic biceps tenodesis, or biceps tenotomy. The database was then queried a second time for patients undergoing arthroscopic rotator cuff repair with concomitant SLAP repair, biceps tenodesis, or biceps tenotomy., Results: From 2002 to 2011, there were 8963 cases reported for the treatment of an isolated SLAP lesion and 1540 cases reported for the treatment of SLAP lesions with concomitant rotator cuff repair. For patients with isolated SLAP lesions, the proportion of SLAP repairs decreased from 69.3% to 44.8% (P < .0001), while biceps tenodesis increased from 1.9% to 18.8% (P < .0001), and biceps tenotomy increased from 0.4% to 1.7% (P = .018). For patients undergoing concomitant rotator cuff repair, SLAP repair decreased from 60.2% to 15.3% (P < .0001), while biceps tenodesis or tenotomy increased from 6.0% to 28.0% (P < .0001). There was a significant difference in the mean age of patients undergoing SLAP repair (37.1 years) versus biceps tenodesis (47.2 years) versus biceps tenotomy (55.7 years) (P < .0001)., Conclusion: Practice trends for orthopaedic board candidates indicate that the proportion of SLAP repairs has decreased over time, with an increase in biceps tenodesis and tenotomy. Increased patient age correlates with the likelihood of treatment with biceps tenodesis or tenotomy versus SLAP repair., (© 2014 The Author(s).)

Background: Graft survivorship, reinjury rates, and career length are poorly understood after anterior cruciate ligament (ACL) reconstruction in the elite collegiate athlete. The purpose of this study was to examine the outcomes of ACL reconstruction in a National Collegiate Athletic Association (NCAA) Division I athlete cohort., Study Design: Case series; Level of evidence, 4., Methods: A retrospective chart review was performed of all Division I athletes at a single public university from 2000 to 2009 until completion of eligibility. Athletes were separated into 2 cohorts: those who underwent precollegiate ACL reconstruction (PC group) and those who underwent intracollegiate reconstruction (IC group). Graft survivorship, reoperation rates, and career length information were collected., Results: Thirty-five athletes were identified with precollegiate reconstruction and 54 with intracollegiate reconstruction. The PC group had a 17.1% injury rate with the original graft, with a 20.0% rate of a contralateral ACL injury. For the IC group, the reinjury rates were 1.9% with an ACL graft, with an 11.1% rate of a contralateral ACL injury after intracollegiate ACL reconstruction. The athletes in the PC group used 78% of their total eligibility (average, 3.11 years). The athletes in the IC group used an average of 77% of their remaining NCAA eligibility; 88.3% of those in the IC group played an additional non-redshirt year after their injury. The reoperation rate for the PC group was 51.4% and was 20.4% for the IC group., Conclusion: Reoperation and reinjury rates are high after ACL reconstruction in the Division I athlete. Precollegiate ACL reconstruction is associated with a very high (37.1%) rate of repeat ACL reinjuries to the graft or opposite knee. The majority of athletes are able to return to play after successful reconstruction., (© 2014 The Author(s).)

Background: Access to orthopaedic care for pediatric patients has been shown in previous studies to be decreased for patients with Medicaid compared with those with private insurance. The relationship between type of insurance and access to care for adult patients with acute rotator cuff tears has not yet been examined. This study aimed to determine if type of health insurance would have an impact on access to care for an adult patient with an acute rotator cuff tear., Methods: Seventy-one orthopaedic surgery practices within the state of North Carolina were randomly selected and contacted on 2 different occasions separated by 3 weeks. The practices were presented with an appointment request for a fictitious 42-year-old man with an acute rotator cuff tear. Insurance status was reported as Medicaid for the first call and as private insurance during the second call., Results: Of the 71 practices contacted, 51 (72%) offered the patient with Medicaid an appointment, whereas 68 (96%) offered the patient with private insurance an appointment. The difference in these rates was statistically significant (P < .001). The likelihood of patients with private insurance obtaining an appointment was 8.8 times higher than that of patients with Medicaid (95% CI: 2.5, 31.5)., Conclusion: For patients with acute rotator cuff tears, access to care is decreased for those with Medicaid compared with those with private insurance. Patients with private insurance are 8.8 times more likely than those with Medicaid to obtain an appointment., Level of Evidence: Basic science, survey study., (Copyright © 2013 Journal of Shoulder and Elbow Surgery Board of Trustees.

Purpose: The aim of this study was to evaluate the biomechanical strength of two 4.5-mm screws and three 3.5-mm screws for fixation of the tibial tubercle after anteromedialization osteotomy., Methods: Anteromedialization of the tibial tubercle was performed on 5 pairs of fresh-frozen cadaveric lower extremities. One leg from each pair was randomized to fixation with two 4.5-mm screws and the contralateral leg to fixation with three 3.5-mm screws. Each specimen was loaded cyclically to simulate an active straight-leg raise and then to failure while displacement of the tubercle fragment was recorded., Results: There was no difference in mean tubercle fragment displacement under cyclic loading at any cycle number (P > .352). Maximum failure load for osteotomies secured with two 4.5-mm screws was 1,459 ± 540 N, and for three 3.5-mm screws it was 1,360 ± 707 N. This was not a statistically significant difference (P = .723). Tubercle migration of 7 mm was chosen as clinical failure. At this amount of displacement, mean load was 1,085 ± 398 N and 764 ± 313 N in the 4.5-mm and 3.5-mm groups, respectively, which was also not significantly different (P = .146)., Conclusions: Both 2 × 4.5-mm and 3 × 3.5-mm screw constructs after tibial tubercle anteromedialization are equally capable of withstanding physiologic forces like those encountered during an active straight-leg raise and have similar failure strength., Clinical Relevance: Although both configurations are comparable, the use of the smaller 3.5-mm screws may reduce the need for hardware removal related to prominence and soft tissue irritation., (Copyright © 2013 Arthroscopy Association of North America.

Background: Bankart repair with multiple anchor holes concentrated in the anterior-inferior glenoid may contribute to glenoid weakening and potentially may induce glenoid failure., Purpose: To compare the biomechanical strength of a Bankart repair construct that used 3 single-loaded suture anchors versus a repair construct that used 2 double-loaded suture anchors., Study Design: Comparative laboratory study., Methods: A standard Bankart lesion was created in 18 human cadaveric shoulders (9 matched pairs). Within each matched pair, 1 repair construct used 3 single-loaded anchors, whereas the other used 2 double-loaded suture anchors. Measured outcomes (load, stiffness, and energy absorbed) were recorded at failure and at 2 mm of labral displacement. Constructs were loaded to failure with a materials testing device that had differential variable reluctance transducers for displacement measurements., Results: The double-loaded anchor construct had a significantly higher ultimate tensile load (944 ± 231 vs 784 ± 287 N; P = .03). For the other measures (load at 2 mm of displacement, energy absorbed at failure and at 2 mm of displacement and stiffness), there were no significant differences between tested constructs., Conclusion: A Bankart repair construct that used 2 double-loaded anchors was either superior to or equal to a repair construct that used 3 single-loaded anchors in all measured outcomes., Clinical Relevance: Using 2 double-loaded suture anchors for a Bankart repair may limit anchor holes in the glenoid and reduce the risk of postsurgical glenoid fracture while providing a stable repair construct.

Revision reconstruction of the anterior cruciate ligament (ACL) introduces several diagnostic and technical challenges in comparison with primary ACL reconstruction. With the increasing numbers of original reconstructions combined with the continued expectation of high-level athletic participation, revision ACL reconstruction is likely to become more frequent. The purpose of this article was to summarize the causes of failure and the evaluation of the patient with recurrent instability. A review of the literature regarding results after revision ACL reconstruction was performed to assist in the decision-making process and patient counseling. Good results can be obtained in terms of functional stability after revision reconstruction, but chondral and meniscal injury as well as unrecognized associated pathologic instability may play a role in diminished outcomes. In addition, a wide variety of surgical techniques are reviewed to address problems associated with tunnel malposition, widening, and pre-existing hardware.

Background: Little work has been made regarding the use of radiographic landmarks in fibular collateral ligament reconstruction. Radiographic tools can be of use to the surgeon in posterolateral reconstruction as secondary checks in the setting of tissue and bony attrition., Hypothesis: Using standardized radiographic imaging, a zone for femoral tunnel placement in lateral collateral ligament (LCL) reconstruction can be identified., Study Design: Descriptive laboratory study., Methods: Eight fresh-frozen unmatched knees, free of any osseous or articular pathological changes, were selected for dissection (mean age, 61.3 years). Skin and surrounding soft tissues were left intact. Subsequent dissection was carried out to identify the true origin of the LCL. A radiographic marker was applied. True lateral radiographs of the distal femur (posterior condyles overlapping) were taken. Digital radiographic images were obtained and analyzed., Results: The Blumensaat line was found to be closely associated with the LCL origin on lateral radiographic imaging. On average, the LCL ligament was found to be 58% (+ or - 4.7%) across the width of the condyle and 2.3 mm (+ or - 2.3 mm) distal to the Blumensaat line. In all specimens, the anatomical LCL origin was found to have less than 5 mm variance from the mean., Conclusion: The LCL origin is located within a specific region that is noted to have a small amount of variance. This is of benefit to the clinician in the traumatic and reconstructive setting where the true origin may not be easily identifiable through dissection., Clinical Relevance: Intraoperative fluoroscopic imaging can be used as an adjunctive tool for femoral tunnel placement during posterolateral corner and LCL reconstruction.

Background: Periodic clinical and radiographic evaluation is commonly recommended by orthopaedic surgeons to monitor patients following total joint arthroplasty, yet the compliance with and efficacy of patient follow-up protocols have not been well defined. The purpose of this study was to evaluate patient compliance with early clinical follow-up after total hip arthroplasty or total knee arthroplasty., Methods: We performed a retrospective review of clinical follow-up compliance for 776 patients who had undergone a total joint arthroplasty in the lower extremity. This cohort included 505 total hip arthroplasties (372 primary and 133 revision procedures) and 271 total knee arthroplasties (195 primary and seventy-six revision procedures). The patients were given one-time verbal instructions by the treating surgeon at the three-month postoperative visit to return for the one-year follow-up evaluation. At the one-year follow-up evaluation, those who returned were once again verbally instructed to return a year later. Demographic factors, functional hip and knee scores, and follow-up compliance at one and two years after surgery were assessed., Results: Patient compliance with clinical follow-up after all arthroplasties was 61% at one year and 36% at two years. With use of a multivariate model for patients who had total hip arthroplasty, the analyses showed that a revision hip procedure (p = 0.006), younger patient age (p = 0.04), and a higher preoperative Harris hip score for gait (p = 0.04) were associated with follow-up compliance at two years. Of the factors analyzed for patients who had total knee arthroplasty, only nonwhite race (p = 0.03) was found to be a positive predictor of follow-up compliance at the two-year follow-up interval., Conclusions: Patient compliance with clinical follow-up after total joint arthroplasty in response to a verbal request made by the surgeon once at three months and once at one year postoperatively was poor in this series.

Athletes engaged in repetitive activity with recent increases in training or competition are at risk for stress fractures of the foot and ankle.

Although many of these injuries may be managed symptomatically, certain types of stress fractures are at higher risk for delayed union, nonunion, or refracture without aggressive immobilization or surgical fixation.
