RESUMEN
Background: Rotator cuff tears are rare injuries in professional athletes who participate in contact sports, and limited data exist to guide players and team physicians regarding outcomes after surgical management. Purpose: To report the outcomes and return-to-play rates of professional contact sport athletes who underwent arthroscopic management of rotator cuff tears. Study Design: Case series; Level of evidence, 4. Methods: All professional athletes of contact sports who underwent arthroscopic management of a rotator cuff tear between 2002 and 2019 at the institution were identified. Patient information collected were age, sport, position, date of injury, date of surgery, and time to return to play; surgical data included tear size, acuity, pattern, and procedure performed. The primary outcome measure was the ability to return to play and the number of games played after surgery. Results: Overall, 10 rotator cuff tears in 9 professional athletes (8 tears in football players and 2 tears in hockey players) were identified; 9 of the tears were full-thickness tears that underwent arthroscopic single-row repair, while 1 was a partial tear that was debrided. Of the 9 athletes, 8 were able to return to play at the same level, at a mean time of 9.5 ± 4.3 months. The mean playing time after surgery was 32 ± 25 games (2.7 ± 2 seasons) for the football players and 22 games (1 season) for the hockey player who returned. Postoperative imaging was available in 8 of the 10 tears, and 7 of 8 (88%) demonstrated a healed repair. One football player and 1 hockey player with large (>3 cm) full-thickness tears did not return to play. The mean age of these players was 34.5 years and both had >10 years of professional playing experience.≥. Conclusion: The study findings demonstrated that the majority (80%; n = 8) of the professional athletes in contact sports in this series were able to return to play at the same level after arthroscopic management of a symptomatic rotator cuff tear.
RESUMEN
BACKGROUND: Surgical management of unstable distal clavicle fractures (DCFs) remains controversial. Traditional open techniques result in acceptable union rates but are fraught with complications. In response to these limitations, arthroscopic techniques have been developed; however, clinical outcome data are limited. PURPOSE: The primary purpose was to systematically evaluate the clinical and radiographic outcomes of arthroscopic fixation of unstable DCFs. The secondary purpose was to characterize the overall complication rate, focusing on major complications and subsequent reoperations. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: A systematic review of the literature was performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and included a search of the PubMed, Web of Science, Cochrane Register of Controlled Trials, EMBASE, and Scopus databases. English-language studies between 2008 and 2019 that reported on outcomes of patients with DCFs who underwent operative fixation using an arthroscopic or arthroscopically assisted surgical technique were included. Data consisted of patient characteristics, fracture type, surgical technique, concomitant injuries, union rates, functional outcomes, and complications. RESULTS: A total of 15 studies consisting of 226 DCFs treated using an arthroscopically based technique were included in the systematic review. The majority of fractures were classified as Neer type II. Most (97%) of the fractures underwent arthroscopic fixation using a cortical button coracoclavicular stabilization surgical technique. Bony union was reported in 94.1% of the fractures. Good to excellent outcomes were recorded in most patients at the final follow-up. The Constant-Murley score was the most widely used functional outcome score; the pooled mean Constant score was 93.06 (95% CI, 91.48-94.64). Complications were reported in 14 of the 15 studies, and the overall complication rate was 27.4%. However, only 12% of these were considered major complications, and only 6% required a reoperation for hardware-related complications. CONCLUSION: Arthroscopic fixation of DCFs resulted in good functional outcomes with union rates comparable to those of traditional open techniques. While the overall complication profile was similar to that of other described techniques, there was a much lower incidence of major complications, including hardware-related complications and reoperations.
RESUMEN
While there is a wealth of research evidencing the benefits of active-learning approaches, the extent to which these teaching practices are adopted in the sciences is not well known. The aim of this study is to establish an evidential baseline of teaching practices across a bachelor of science degree program at a large research-intensive Australian university. Our purpose is to contribute to knowledge on the adoption levels of evidence-based teaching practices by faculty within a science degree program and inform our science curriculum review in practical terms. We used the Teaching Practices Inventory (TPI) to measure the use of evidence-based teaching approaches in 129 courses (units of study) across 13 departments. We compared the results with those from a Canadian institution to identify areas in need of improvement at our institution. We applied a regression analysis to the data and found that the adoption of evidence-based teaching practices differs by discipline and is higher in first-year classes at our institution. The study demonstrates that the TPI can be used in different institutional contexts and provides data that can inform practice and policy.
