We present a method for single-Achilles allograft medial collateral ligament (MCL) and posterior cruciate ligament (PCL) reconstruction that eliminates the risk of tunnel intersection, stiffens the construct, and maximizes utilization of allograft tissue. An Achilles tendon allograft is prepared with an 11- to 12-mm bone plug with a gradual taper to 7 mm over approximately 15 cm. A transtibial PCL tunnel is created under fluoroscopic and arthroscopic guidance. The femoral tunnel is prepared in an "outside-in" fashion under direct arthroscopic visualization, originating at the anatomic origin of the MCL on the medial epicondyle and entering the joint at the anatomic origin of the anterolateral bundle of the PCL. The Achilles graft is pulled into the joint through the tibial tunnel and routed into the femoral tunnel so that the soft tissue exits at the medial epicondyle. The bone plug is fluoroscopically guided to the posterior aperture of the tibial tunnel and fixed with a bioabsorbable interference screw. The pretensioned graft is fixed in the femoral tunnel via interference screw fixation with the knee in 90 degrees of flexion. The isometric position of the MCL insertion is identified with a K-wire isometer, and the graft is fixed in place at this point by use of an interference screw or screw and washer.

Simulation-based training is required by many medical specialties. Barriers, however, have prevented widespread implementation of simulators for arthroscopic training. The advantages of arthroscopic simulator-based training of residents include decreased errors, decreased cost of training, and improved patient care. Before an educational program can focus on the type of simulator, it is essential to have a validated curriculum and framework for how to use those simulators. One of the most validated systems is called proficiency-based progression training. Proficiency-based progression is essentially a paradigm in which basic skills must be mastered and demonstrated via objective evaluation, before moving on to more advanced skills. There are a variety of different validation methods and tools that have been described, with the Arthroscopic Surgical Skill Evaluation Tool being the most widely used tool. It is essential that any simulator has evidence and validation that it will ultimately improve surgical skills in the operating room. In the future, emerging technologies such as virtual reality, augmented reality, and three-dimensional printing will likely play a major role in the creation of newer simulators and may improve access to residents throughout the world.

Objectives: To compare patient-reported outcomes (PROs), range of motion (ROM), and complication rates for proximal humerus fractures managed nonoperatively or with open reduction internal fixation (ORIF)., Design: Retrospective cohort., Setting: Academic level 1 trauma center., Patients/participants: Four hundred thirty-one patients older than 55 years were identified retrospectively. 122 patients were excluded. 309 patients with proximal humerus fractures met inclusion criteria (234 nonoperative and 75 ORIF). After matching, 192 patients (121 nonoperative and 71 ORIF) were included in the analysis., Intervention: Nonoperative versus ORIF (locked plate) treatment of proximal humerus fracture., Main Outcome Measurements: Early Visual Analog Score (VAS), ROM, PROs, complications, and reoperation rates between groups., Results: At 2 weeks, ORIF showed lower VAS scores, better passive ROM, and patient-reported outcomes measurement information system (PROMIS) scores ( P < 0.05) compared with nonoperative treatment. At 6 weeks, open reduction internal fixation (ORIF) had lower VAS scores, better passive ROM, and PROMIS scores ( P < 0.05) compared with nonoperative treatment. At 3 months, ORIF showed similar PROMIS scores ( P > 0.05) but lower VAS scores and better passive ROM ( P < 0.05) compared with nonoperative treatment. At 6 months, ORIF showed similar VAS scores, ROM, and PROMIS scores ( P > 0.05) compared with nonoperative treatment. There was no difference in secondary operation rates between groups ( P > 0.05). ORIF patients trended toward a higher secondary reoperation rate (15.5% vs. 5.0%) than nonoperative patients ( P = 0.053)., Conclusions: In an age-, comorbidity-, and fracture morphology-matched analysis of proximal humerus fractures, ORIF led to decreased pain and improved passive ROM early in recovery curve compared with nonoperative treatment that normalized after 6 months between groups., Level of Evidence: Therapeutic Level III.

Background: This study compares patient-reported outcomes and range of motion (ROM) between adults with an AO Foundation/Orthopaedic Trauma Association type C proximal humerus fracture managed nonoperatively, with open reduction and internal fixation (ORIF), and with reverse shoulder arthroplasty (RSA)., Methods: This is a retrospective cohort study of patients >60 years of age treated with nonoperative management, ORIF, or RSA for AO Foundation/Orthopaedic Trauma Association type 11C proximal humerus fractures from 2015 to 2018. Visual analog scale pain scores, Patient-Reported Outcomes Measurement Information System (PROMIS) scores, ROM values, and complication and reoperation rates were compared using analysis of variance for continuous variables and chi square analysis for categorical variables., Results: A total of 88 patients were included: 41 nonoperative, 23 ORIF, and 24 RSA. At the 2-week follow-up, ORIF and RSA had lower visual analog scale scores and lower PROMIS pain interference scores ( P  < .05) than nonoperative treatment. At the 6-week follow-up, ORIF and RSA had lower visual analog scale, PROMIS pain interference, and PF scores and better ROM ( P  < .05) than nonoperative treatment. At the 3-month follow-up, ORIF and RSA had better ROM and PROMIS pain interference and PF scores ( P  < .05) than nonoperative treatment. At the 6-month follow-up, ORIF and RSA had better ROM and PROMIS PF scores ( P  < .05) than nonoperative treatment. There was a significantly higher complication rate in the ORIF group than in the non-operative and RSA groups ( P  < .05)., Conclusion: The management of AO Foundation/Orthopaedic Trauma Association type 11C proximal humerus fractures in older adults with RSA or ORIF led to early decreased pain and improved physical function and ROM compared to nonoperative management at the expense of a higher complication rate in the ORIF group.

A marginal number of adolescents meet the recommended guidelines of 60 minutes of moderate to vigorous daily physical activity, and even fewer underrepresented minority females achieve this metric as compared to their male and white counterparts. While potential interventions exist to address these low levels of activity, which is a known risk for acute injuries and chronic disease, there is lack of consensus on the devices used to measure the intensity of daily activity levels. Wearable activity trackers such as Fitbit™ have been utilized to quantify human motion and exercise intensity, but there is little precedence for these measures being assessed in adolescent wearers. Thus, our objective was to assess the feasibility of using Fitbit to assess daily physical activity levels in underrepresented minority adolescent females, who attend an economically challenged urban high school, over the course of a physical activity intervention. We also aimed to identify candidate Fitbit outcome measures for future prospective studies. A 10-week physical activity intervention was implemented in a cohort of 24 high school female athletes. From within this cohort, a sample of five students were provided Fitbit™ devices, from which we obtained data sets from three students. Activity on the days of the exercise intervention was measured and compared to activity on non-intervention days. Post-hoc assessments were performed based on individual heart rate reserves, the predefined levels set by the Inspire Fitbit™ device and the American College of Sports Medicine (ACSM) 2009 guidelines. The results showed that while compliance is challenging, wearable devices can be used to assess daily physical activity levels and intensities in underrepresented minority high school female athletes during an extended physical activity intervention. Of the Fitbit outcomes currently available, assessment of moderate-vigorous activity (min/day) appeared to be the best as a measure of global physical activity. Prospective research is now warranted to validate these thresholds, and to test novel interventions for their ability to transition inactive adolescents at risk of sports-related injuries and long-term chronic disease, into a more active lifestyle., Competing Interests: The authors declare no potential conflicts of interest.

Two major health concerns with female high school athletes are: 1) psychosocial wellness, and 2) sports-related injuries. It is also known that these health concerns are much greater for minority students who attend high school in economically depressed cities. While it has been well-established that exercise is an effective intervention for these health concerns, there are no established outcome measures to quantitatively assess athletic performance and injury prevention training interventions in this population. Previously, we have demonstrated the utility of Patient-Reported Outcomes Measurement Information System (PROMIS) as a robust outcome measure following ACL reconstruction. Functional Movement Screening (FMS) has been used as a tool to determine injury risk in female collegiate athletes. Since these tools are broadly available, we completed a research study of urban underrepresented minority and suburban female high school athletes, to assess the feasibility and utility of these tools to measure changes in this population during 10-weeks of athletic training. No adverse events of the training or study were reported. A Kaplan-Meier assessment of the data revealed that there was high student retention throughout the 10 weeks. In addition, we found no difference in weekly attendance between the students that completed the intervention vs. the dropouts (while they were in the program), indicating that the students were highly motivated to attend when possible. While no significant differences were found for fatigue and physical function, the intervention significantly improved anxiety, peer relationships, pain interference, and trended towards significance for depression (p<0.05). In terms of physical performance, bench press, combined Pro Agility, and total FMS were all significantly improved (p<0.05). Surprisingly, there were 10 students (67%) in peril of sports- related injury (FM˂14) at the start of the intervention, and all but 1 (90%) eliminated this serious risk factor. Collectively, these results demonstrate the feasibility of PROMIS and FMS outcomes to assess the efficacy of physical training interventions, in underrepresented minority female high school students, which warrants investigation in a formal prospective study., Competing Interests: The authors declare no potential conflicts of interest.

The shoulder is a complex joint, with a wide range of motion and functional demands. An understanding of the intricate network of bony, ligamentous, muscular, and neurovascular anatomy is required in order to properly identify and diagnose shoulder pathology. There exist many articulations, unique structural features, and anatomic relationships that play a role in shoulder function, and therefore, dysfunction and injury. Evaluation of a patient with shoulder complaints is largely reliant upon physical exam. As with any exam, the basic tenets of inspection, palpation, range of motion, strength, and neurovascular integrity must be followed. However, with the degree of complexity associated with shoulder anatomy, specific exam maneuvers must be utilized to isolate and help differentiate pathologies. Evaluation of rotator cuff injury, shoulder instability, or impingement via exam guides clinical decision-making and informs treatment options.

Background: Several procedures have been proposed to address irreparable rotator cuff (RC) tears with pseudoparalysis. One recently proposed procedure is superior capsular reconstruction (SCR) using a tensor fasciae latae (TFL) autograft., Hypothesis: SCR with a locally available long head of the biceps tendon (LHB) autograft is biomechanically equivalent to SCR using TFL autograft for preventing superior humeral migration and the development of RC arthropathy in patients with irreparable RC tears., Study Design: Controlled laboratory study., Methods: Ten cadaveric shoulders (5 matched pairs) were tested. One shoulder from each pair was randomly assigned to the LHB reconstruction group using our novel technique, while the contralateral side was assigned to the TFL reconstruction group. SCR with a TFL autograft was performed based on previously described techniques. Massive RC tears were created by detachment of the supraspinatus and infraspinatus footprints from the greater tuberosity. The force required to superiorly translate the humerus 1.5 cm was then tested and recorded using a servohydraulic testing machine under 2 conditions: (1) after a massive RC tear and (2) after SCR with either a TFL autograft or an LHB autograft., Results: SCR with an LHB autograft required 393.2% ± 87.9% ( P = .029) of the force needed for superior humeral migration in the massive RC tear condition, while SCR with a TFL autograft required 194.0% ± 21.8% ( P = .0125). The LHB reconstruction group trended toward a stronger reconstruction when normalized to the torn condition ( P = .059)., Conclusion: SCR with an LHB autograft is a feasible procedure that is shown to be biomechanically equivalent and potentially even stronger than SCR with a TFL autograft in the prevention of superior humeral migration., Clinical Relevance: This new technique may help to prevent superior humeral migration and the development of RC arthropathy in patients with irreparable RC tears., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: G.N. is a paid speaker/presenter for Arthrex.

Lesser tuberosity osteotomy (LTO) and subscapularis tenotomy (ST) are used for takedown of the subscapularis during shoulder arthroplasty. LTO offers the theoretical but unproven benefit of improved healing and function of the subscapularis. However, humeral stem subsidence and loosening may be greater when osteotomy is performed, which may compromise functional outcomes. Our hypothesis is that no difference in proximal collar press-fit humeral stem subsidence or loosening exists, with no impairment of functional outcomes using the LTO technique. Radiographs of 39 shoulders from 35 patients who underwent shoulder arthroplasty with a minimum of 1 year of radiographic follow-up were included in the study cohort. All patients received the same press-fit implant (Bigliani-Flatow; Zimmer Biomet). We collected data including demographic information; radiographic measurements, including humeral-acromial distance (HAD); subsidence; subluxation index; the presence of lucent lines >2 mm; and functional outcome scores using the Western Ontario Osteoarthritis of the Shoulder Index, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, and the Constant score. Subsidence was 2.8 ± 3.1 mm for LTO vs 2.5 ± 3.1 mm for ST (P = .72). HAD did not differ between the LTO and ST groups preoperatively (9.5 ± 2.4 mm vs 10.9 ± 2.7 mm, P = .11). The first postoperative and final follow-up films for HAD for the LTO and ST groups showed a statistically significant difference (first postoperative film, 11.9 ± 3.7 mm vs 15.9 ± 4.5 mm, P = .005; final follow-up film, 11.8 ± 3.2 mm vs 14.5 ± 3.9 mm, P = .03). We identified no differences in subsidence, lucent lines >2 mm, posterior subluxation, and Constant, and DASH functional outcome scores for patients undergoing total shoulder arthroplasty via the LTO vs ST techniques with the same proximal collar press-fit humeral stem at short-term follow-up., Competing Interests: Authors' Disclosure Statement: Dr. Voloshin reports that he is a paid consultant for Zimmer Biomet, Smith & Nephew, Arthrex, and Arthrosurface.

Safe and effective arthroscopic surgery requires ambidextrous motor skills. The current study examined dominant versus non-dominant hand performance on a virtual reality serious game in a group of expert arthroscopic surgeons (n=15) compared to a group of orthopedic surgery residents (n=10). A virtual reality Tetris game was performed with the arthroscopic camera and arthroscope in one hand, using an arthroscopic grasping tool in the opposite hand to manipulate the virtual Tetris blocks onto the game grid. A second run was performed after swapping instruments between hands. The order of hand testing was randomized. There was no statistically significant difference in exercise time, grasper path length, or camera path length between the right and left hands of the expert surgeons. In contrast, there were statistically significant differences in all of these parameters between the two hands for the orthopedic surgery residents, with better performance when the grasping tool was used in the dominant hand. The findings of this study suggest that virtual reality games which incorporate progressive cognitive loading could be used to facilitate training, automation, and objective assessment of surgical motor skills.

The purpose of this study was to determine the frequency of use, perceived effectiveness, and preference for arthroscopic surgical skill training resources. An electronic survey was sent to orthopedics residents, residency program directors, and orthopedic sports medicine attending physicians in the United States. The frequency and perceived effectiveness of 10 types of adjunctive arthroscopic skills training was assessed. Residents and faculty members were asked to rate their confidence in resident ability to perform common arthroscopic procedures. Surveys were completed by 40 of 152 (26.3%) orthopedic residency program directors, 70 of 426 (16.4%) sports medicine faculty, and 235 of 3,170 (7.4%) orthopedic residents. The use of adjunctive methods of training varied from only 9.8% of programs with virtual reality training to 80.5% of programs that used reading of published materials to develop arthroscopic skill. Practice on cadaveric specimens was viewed as the most effective and preferred adjunctive method of training. Residents trained on cadaveric specimens reported increased confidence in their ability to perform arthroscopic procedures. The resources for developing arthroscopic surgical skill vary considerably across orthopedic residency programs in the United States. Adjunctive training methods were perceived to be effective at supplementing traditional training in the operating room., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Background: The optimal method-subscapularis peel (SP) or lesser tuberosity osteotomy (LTO)-for takedown of the subscapularis during total shoulder arthroplasty (TSA) is controversial. This study compares the functional outcomes in a 2-surgeon cohort using the 2 techniques., Methods: Patients who underwent TSA with a minimum 1 year of follow-up were evaluated. Physical and ultrasound examinations of the operative shoulder were performed. Radiographs were evaluated for osteotomy healing. Patients completed the Western Ontario Osteoarthritis of the Shoulder (WOOS) index, Disability of the Arm, Shoulder, and Hand (DASH), and Constant Scores., Results: Subscapularis tenotomy (n = 32) and LTO (n = 28) patients were similar in age, hand dominance, and sex. Follow-up duration for subscapularis tenotomy and LTO patients differed (31.7 vs 22.1 months, P = .003). SP patients demonstrated increased external rotation (69° ± 12° vs 60° ± 11°). Belly press and bear hug resistance were not significantly different. WOOS (P = .13), DASH (P = .71), and Constant Scores (P = .80) were not significantly different. After controlling for follow-up imbalance, the WOOS score difference was statistically significant (91.5 ± 10.2 for LTO vs 82.1 ± 18.9 for SP, P = .05) but not clinically significant. By ultrasonography assessment, 4 subscapularis tendons were abnormal in the SP group (3 attenuated, 1 ruptured), and all tendons were normal in the LTO group. Patients with an abnormal ultrasound result had significantly inferior WOOS (88 ± 15 vs 65 ± 18) and DASH (11.5 ± 11.4 vs 25.9 ± 11.2) scores. Belly press resistance was significantly decreased, bear hug resistance trended lower, and external rotation was increased in the abnormal ultrasound group., Conclusions: Abnormal subscapularis tendons identified by ultrasonography only in the SP group correlate with clinically significant inferior functional outcome scores., (Copyright © 2014 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: The Basic Arthroscopic Knee Skill Scoring System (BAKSSS) has construct validity as an objective measure of arthroscopic proficiency when used to assess the task of performing arthroscopic meniscectomies on cadaver knees. The reliability of this instrument is unknown., Questions/purpose: We asked whether (1) a simple modification of the BAKSSS would show construct validity similar to that in the initial BAKSSS study, (2) this assessment would be reliable, and (3) this assessment could be used as a high-stakes pass or fail test., Methods: Twenty-three orthopaedic residents performed diagnostic knee arthroscopies on cadaveric knee specimens. Their competency was assessed by three live raters using the modified BAKSSS. Interrater reliability was assessed by comparing the scores given by each rater to each subject., Results: The modified BAKSSS showed construct validity with junior residents achieving lower scores (mean score, 20) than senior residents (mean score, 33). The modified BAKSSS had an interrater reliability of kappa = 0.685-0.852. The modified BAKSSS had a kappa = 0.543 when used as a proficiency test for diagnostic arthroscopy., Conclusions: The modified BAKSSS is useful for assessing diagnostic knee arthroscopy proficiency. Future scoring systems should be designed to be generalizable so they can be applied to multiple procedures without the need for modification, allow for video-based assessment, and must be rigorously tested for reliability and other types of validity (eg, face validity, content validity, and criterion-related validity)., Clinical Relevance: Having a valid and reliable assessment of basic arthroscopic procedures may allow educators to more adequately evaluate individual residents and the effectiveness of various training modalities.

Background: The use of surgical simulation in orthopaedic education is increasing; however, its ideal place within the training curriculum remains unknown. The purpose of this study was to determine the effectiveness of training novice surgeons on an anatomic dry model of the knee prior to training them to perform diagnostic arthroscopy on cadaveric specimens., Methods: Fourteen medical students were randomly assigned to two groups. The experimental group was trained to perform diagnostic arthroscopy of the knee on anatomic dry models prior to training on cadaveric specimens. The control group was trained only on cadaveric specimens. Proficiency was assessed with use of a modified version of a previously validated objective assessment of arthroscopic skill, the Basic Arthroscopic Knee Skill Scoring System (BAKSSS). The mean number of trials required to attain minimal proficiency when performing diagnostic knee arthroscopy was compared between the groups. The cumulative transfer effectiveness ratio (CTER) was calculated to measure the transfer of skills acquired by the experimental group., Results: The mean number of trials to demonstrate minimum proficiency was significantly lower in the experimental group (2.57) than in the control group (4.57) (p &lt; 0.01). The mean time to demonstrate proficiency was also significantly less in the experimental group (37.51 minutes) than in the control group (60.48 minutes) (p &lt; 0.01). The CTER of dry-model training for the task of performing diagnostic knee arthroscopy on cadaveric specimens was 0.2., Conclusions: Previous training utilizing an anatomic dry knee model resulted in improved proficiency for novice surgeons learning to perform diagnostic knee arthroscopy on cadaveric specimens. A CTER of 0.2 suggests that dry models can serve as a useful adjunct to cadaveric training for diagnostic knee arthroscopy but cannot entirely replace it within the orthopaedic curriculum. Further work is necessary to determine the optimal amount of training on anatomic dry models that will maximize transfer effectiveness and to determine how well skills obtained in the simulated environment transfer to the operating room.

Football, one of the country's most popular team sports, is associated with the largest overall number of sports-related, catastrophic, cervical spine injuries in the United States (Mueller, 2007). Patient handling can be hindered by the protective sports equipment worn by the athlete. Improper stabilization of these patients can exacerbate neurologic injury. Because of the lack of consensus on the best method for equipment removal, a study was performed comparing three techniques: full body levitation, upper torso tilt, and log roll. These techniques were performed on an intact and lesioned cervical spine cadaveric model simulating conditions in the emergency department. The levitation technique was found to produce motion in the anterior and right lateral directions. The tilt technique resulted in motions in the posterior left lateral directions, and the log roll technique generated motions in the right lateral direction and had the largest amount of increased instability when comparing the intact and lesioned specimen. These findings suggest that each method of equipment removal displays unique weaknesses that the practitioner should take into account, possibly on a patient-by-patient basis.

Background: Controversy still exists about treatment of syndesmotic injuries. This study compared the fixation strengths and biomechanical characteristics of two types of ankle fracture syndesmotic fixation devices: the barbed, round staple and the 4.5-mm cortical screw., Methods: Cadaveric testing was done on 21 fresh-frozen knee disarticulation specimens in biaxial servohydraulic Instron testing equipment. Submaximal torsional loads were applied to specimens in intact and Weber C bimalleolar fracture states. The specimens were then fixed with one of two techniques and again subjected to submaximal torsion and torsion to failure. Biomechanical parameters measured included tibiofibular translation and rotation, maximal torque to failure, and degrees of rotation at failure., Results: Compared to the intact state before testing, the staple held the fibula in a more anatomic position than the screw for mediolateral and anterior displacements (p < 0.01). With submaximal torsional testing, the staple restored 85% of the tibiofibular external rotation and all of the posterior translation values as compared to the intact state. The screw resulted in 203% more tibiofibular medial translation and 115% more external rotation than the intact state. The degree of tibial rotation during submaximal torsional loading was restored to within 15% of intact values but was 21% less with the screw. There was no statistical difference between the screw and staple when tested in load to failure. Tibiotalar rotation at failure was statistically different with the staple construct, allowing more rotation as compared to the screw., Conclusion: The staple restored a more physiologic position of the fibula compared to the syndesmotic screw. Both provided similar performance for the load to failure testing, while the screw reduced tibial rotation more after cyclic loading. There was more tibial rotation before failure for the staple, suggesting a more elastic construct. This study provides biomechanical data to support the clinical use of the syndesmotic staple.
