Although total ankle arthroplasty (TAA) is becoming a progressively common procedure with a reported 10-fold increase in its prevalence over the past 2 decades; there is still limited large-scale data regarding its overall outcome. Using the National Inpatient Sample (NIS) database, patients who underwent TAA between 2016 and 2019 were identified (ICD-10 CMP code). Data regarding demographic details, co-morbidities, geographic locations of procedure, hospital stay, expenditure incurred, and complications encountered were analyzed. Additionally, a comprehensive subgroup analysis was performed to evaluate the impact of multiple preoperative variables (including gender, diabetes, obesity, CKD and tobacco abuse) on the patient outcome. Overall, 5087 patients (mean age: 65.1 years, 54% males, 85% Caucasians, 75% from large metropolitan regions) underwent TAA. Eighty eight percent of patients were discharged to home; and the mean length of hospital stay and hospital-related expenditure were 1.7 ± 1.41 days and $92,304.5 ± 50,794.1, respectively. The overall complication rate was 8.39% {commonest medical complications: anemia [131 (2.6%) patients) and acute renal failure [37 (0.7%) patients]; commonest local complication: periprosthetic mechanical adversities [90 (1.7%) patients]}. Female and CKD patients demonstrated significantly higher risks of medical (female: p = .003; CKD: p.001) and surgical (female: p = .005; CKD: p.019) complications; while obesity substantially enhanced the risk of medical adversities (p.001). Based on our study, we could conclude that the rates of TAA in the United States are on the rise, especially in regions with population greater than 250,000. TAA is a safe procedure with relatively low complication rates. The complications and hospital-associated expenditure seem to vary between different patient subgroups.

The objective of this study was to determine the survivorship of anatomic total shoulder arthroplasty (aTSA) and reverse TSA (rTSA) over a medium-term follow-up in a large population-based sample and to identify potential risk factors for revision surgery.The State Inpatient Database from the Healthcare Cost and Utilization Project was used to identify patients who underwent aTSA or rTSA from 2011 through 2015 using ICD9 codes. We modeled the primary outcome of time to revision or arthroplasty using the Cox proportional hazards model. The predictors of revision surgery in the model include aTSA versus rTSA, indication for surgery, age, sex, race, urban versus rural residence, hospital length of stay zip code-based income quartile classification, and Elixhauser comorbidity readmission score.Among 43,990 patients in this study, 1,141 (4.0%) underwent revision or implant removal over the 4-year study period. The median age was 71 years, and 57% of patients were female. Indications for the index surgery included primary osteoarthritis (75.2%), cuff tear (8.5%), acute fracture (7.0%), malunion/nonunion (1.4%), and other (7.8%). Among these indications for surgery, the risk of revision or removal was greatest in patients who underwent the primary procedure for malunion/nonunion (hazard ratio [HR] 2.39, 95% confidence interval [CI] 1.69 to 3.39) compared with the reference of primary osteoarthritis. Male patients who underwent aTSA were less likely to need revision surgery than male patients who underwent rTSA (HR: 0.59, 95% CI 0.49 to 0.71), and the opposite relationship was observed in female patients (HR: 1.41, 95% CI 1.18 to 1.69). Age, length of stay, and Elixhauser comorbidity score were predictive of revision surgery (P0.0001, P = 0.0005, P0.0001, respectively), whereas race, urban versus rural, and zip code-based income quartile were not.aTSA and rTSA showed excellent 4-year survivorship of 96.0% in a large population-based sample. aTSA and rTSA survivorships were similar at the 4-year follow-up.

Purpose Total ankle replacement (TAR) and ankle arthrodesis (AA) are two commonly performed procedures for end-stage arthritis of the ankle joint. The aim of this study was to analyze the differences in the rates of complications and reoperations at both 30 days and one year within a matched sample of TAR and AA patients from a large database population. Methods A commercially available patient database record, known as the PearlDiver database (www.pearldiverinc.com, Colorado Springs, CO, USA), was used for this study. Patients undergoing TAR and AA were identified using Current Procedural Terminology (CPT) codes. After matching both TAR and AA groups for confounding variables, such as diabetes, smoking, obesity, and comorbidities scores, the differences in the rates of complications at 30 days and one year and the rate of reoperation at one year were evaluated in both groups. Results After matching for confounding variables, there were 1287 patients in each group. There was no significant difference in the male/female ratio. Within each group, 430 patients were diabetic, 102 patients smoked, and 543 patients were obese. The rate of surgical site infection (SSI) and wound dehiscence were higher at 30 days in the AA group. About 63.45% of complications happened after 30 days. The AA group showed a higher rate of SSI, wound dehiscence, mechanical complications, and pneumonia at one year. The rate of reoperation was also higher in the AA group at one year. Conclusion Ankle arthrodesis is associated with a higher rate of local and systemic complications at 30 days and one year, along with a higher reoperation rate at one year, when compared to total ankle replacement. Most complications happened after 30 days, suggesting that studies reporting complications within 30 days following AA and TAR may underestimate the true rates of complications.

Objectives: Femoroacetabular Impingement(FAI) is a condition caused by repetitive motion of abnormal hip osseous anatomy that contributes to labral and chondral injury. An understanding of radiographic parameters associated with successful primary surgery has not been well established. The primary objective was to determine pre-operative radiographic parameters that predict reoperation for FAI and, secondarily, correlate radiographic measures and outcomes in these patients. Methods: A prospectively-collected institutional registry of adolescent patients (age Results: Eighty-seven patients underwent primary surgery (56 surgical dislocations vs 31 scopes) for FAI. The average age at time of primary operation was 16.27 years(73.6%Female). 10 underwent re-operation (11.5%) at an average of 20.6 months from primary surgery. No differences were found in demographics, activity, surgery type, labral disease, or alpha angle for re-operation vs. non-reoperation. The LCEA, FEAR Index, Sharps, and Tönnis angle were significantly different (p-8.8 were predictors for increased risk of reoperation. Patients with LCEA21° (6%). Patients with FEAR index-8.8 (5%). Patients who achieved MCID (61.9%) had lower BMI, worse pre-operative PROs, and better post-operative PROs at 2-years. Alpha, Tönnis, and Sharp’s angles were positively correlated with 2+ year PROs, while LCEA was negatively correlated(pConclusions: In patients undergoing treatment for FAI, a reoperation was associated with radiographic signs of hip dysplasia, indicating that patients with a shallower acetabulum are at risk for a repeat operation. Surgeons can utilize these parameters to help in surgical decision making, better predict outcomes and to counsel patients the need for potential subsequent surgery.

Objectives: To determine the safety and acute tolerance of performing prostate high dose rate (HDR) brachytherapy in a free-standing cancer center setting, and to report our approach in delivering such treatment. Methods: Patients treated with prostate HDR from the inception of our program through December 2004 were included. Disease- and treatment-related information was gathered from chart review. Acute side effects were obtained from both chart review and questioning the patient at follow-up visits. Results: A total of 234 patients were treated with 459 HDR needle insertions. Nearly all patients were treated with external beam irradiation, and the majority also received adjuvant hormonal manipulation. There were no adverse events related to transport to the free-standing cancer center. Treatment was well tolerated, with only 3.7% of procedures developing retention requiring catheter placement; 20% of patients reported significant postimplant dysuria, mean duration of any dysuria being 7.5 days. Postimplant retention and length of any dysuria were not found to be related to any of the analyzed factors. Severity of dysuria was found to be related only to timing of external beam. Postimplant retention was more frequent for some physicians, but this finding was not statistically significant. Conclusions: Prostate HDR brachytherapy can be delivered safely and effectively in an ambulatory free-standing cancer center setting when done by a urology and radiation oncology team working in close conjunction. Treatment combining HDR brachytherapy as described with external beam radiation, with or without androgen manipulation, is well tolerated by the patient.
