Abstract
IMPORTANCE: Traumatic anterior shoulder instability remains common for the adolescent athletes. AIM OR OBJECTIVE: To perform a systematic review on the outcomes and return to sport (RTS) following Bankart repair in adolescent athletes. EVIDENCE REVIEW: A systematic review using the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines was conducted of studies reporting outcomes following open and/or arthroscopic Bankart repair using modern suture anchors following traumatic anterior shoulder dislocations in adolescent patients (ages 10-19 years). Quality assessment was evaluated with ROBINS-I and MINORS instruments. The outcomes analysed included RTS, timetable to unrestricted activity, recurrent instability and revision surgery. FINDINGS: This systematic review identified 11 studies comprising 461 adolescent athletes with a mean age of 15.7 years (range, 11-19 years) and an average follow-up of 48.8 months (range, 22-85.2 months). A total of 392 patients (400 shoulders) underwent arthroscopic Bankart repair, while the remaining 69 patients (69 shoulders) underwent an open procedure. The average MINORS score was 9.6 for non-comparative studies and 17 for comparative studies. ROBINS-I revealed six studies to have a moderate risk of bias, while the remaining five studies presented serious risk of bias. There was an overall 81.5% rate of RTS to preinjury levels of athletic competition at an average of 5.3 months following Bankart repair for traumatic anterior shoulder instability. The overall total mean incidence of recurrent instability was 18.5%, while the mean incidence of revision surgery was 12.1%. Contact athletes had a 31.1% and 13% rate of recurrence and revision surgery, respectively. In comparison, collision athletes were shown to have a 10.4% and 1.4% incidence of recurrent instability and revision surgery, respectively. CONCLUSIONS AND RELEVANCE: Adolescent athletes who undergo Bankart repair for traumatic anterior shoulder instability have an 81.5% rate of RTS to preinjury levels of play at an average of 5 months following surgery. The overall total mean incidence of recurrent instability in the adolescent population is 18.5%, while the mean incidence of revision surgery is 12.1%. The results of anterior shoulder stabilisation in contact athletes is much less predictable, with higher reported rates of recurrent instability and revision surgery. LEVEL OF EVIDENCE: Level IV.
