BACKGROUND: Superior labrum anterior-posterior (SLAP) tears are common shoulder injuries, especially in overhead athletes. Often, initial management of these injuries is non-surgical with focused rehabilitation. The purpose of this review was to evaluate the outcomes of non-surgical management of SLAP tears in athletes METHODS: A systematic review was performed for articles published before March 2021 using key search terms pertaining to clinical studies evaluating the non-surgical treatment of SLAP tears in adult patients published in English-language literature. Abstracts and manuscripts were independently reviewed by two co-authors to determine eligibility. Return-to-play rate and return to prior athletic performance was determined by combining results across studies. RESULTS: Five articles met the inclusion criteria. There were 244 total athletes (162 elite or higher-level athletes). The mean ages ranged from 20.3 to 38.0 years of age. Type II SLAP tears were most common; baseball, softball and weightlifting were the most common sports involved. The return-to-play rate was 53.7% in all athletes and 52.5% in elite or higher-level athletes. In athletes who were able to complete their non-operative rehabilitation program, the return-to-play rate was 78% in all athletes and 76.6% in elite or higher-level athletes. The overall rate of return to prior performance was 42.6%, which increased to 72% for those athletes who were able to complete their rehabilitation. Patients who discontinued the rehabilitation protocol in favor of surgery had an average of eight physical therapy sessions compared to 20 sessions for patients with successful non-operative treatment. Timing of return to play was generally less than 6 months in studies that reported it. Patient-reported outcomes, including the American Shoulder and Elbow Surgeons score and visual analog scale, all improved significantly following non-surgical treatment. Factors associated with failure of non-surgical management included older age, participation in overhead sports (especially baseball pitchers), traumatic injury, positive compression rotation test, concomitant rotator cuff injury, longer baseball career, longer symptomatic period and the presence of a Bennett spur. CONCLUSIONS: Overall, non-operative treatment of SLAP tears in athletes can be successful, especially in the subset of patients who are able to complete their rehabilitation program prior to attempting a return to play. While non-operative treatment should be considered the first-line of treatment for most SLAP tears, there are some factors which may be associated with failure of conservative treatment; therefore, further high level, prospective studies would be beneficial to identify those athletes most likely to respond favorably to non-operative treatment.
