Arthroscopic Labral Reconstruction With a Modi fi ed Inferior Capsular Shift Allows Return to Sport and Excellent Outcomes in Contact and Noncontact Athletes With Anterior Shoulder Instability at Minimum 5-Year Follow-Up

Purpose: To compare return to sport, functional outcomes, recurrence of instability, and osteoarthritis (OA) between collision/contact and limited/noncontact athletes following arthroscopic labral reconstruction with a modi fi ed inferior capsular shift for anterior shoulder instability. Methods: Athletes underwent an arthroscopic labral reconstruction with a modi fi ed inferior capsular shift by the senior author between 1999 and 2018. Inclusion criteria were labral stripping from 12 (just beyond the biceps anchor) to 6 o ' clock, less than 20% glenoid bone loss, active sports participation, and no previous surgery. Athletes were divided into collision/contact and limited/noncontact groups. Outcome measures, physical examination, and radiographic evaluation were collected at a minimum 5 -year follow-up. Reoperations or any subjective laxity were considered failures. Radiographs were analyzed for OA using the Samilson-Prieto Radiological Classi fi cation. Results: Ninety-two patients underwent arthroscopic labral reconstruction with a modi fi ed inferior capsular shift. Sixty-four met the inclusion criteria. Thirty-eight (age = 26.0 +/- 8.0 years) participated in at least 1 collision/contact sport, and 26 (age = 38.0 +/- 9.0 years) participated in limited/noncontact sports. Two (5%) collision/contact and 3 (12%) limited/noncontact athletes had traumatic reinjury requiring revision surgery. Of the remaining athletes (59/64), minimum 5 -year follow-up was obtained on 54 (92%), with a mean follow-up of 12 +/- 4 years (range 5-23 years). All athletes returned to their original sport at the same level. There was no signi fi cant difference between collision/contact and limited/noncontact athletes in timing of return to sports (5.2 +/- 1.9 and 6.0 +/- 3.1 months, respectively; P = .389). There were no signi fi cant differences between groups on any outcomes scores. Conclusions: Arthroscopic labral reconstruction with a modi fi ed inferior capsular shift addressed anterior instability with return to sport for both collision/contact and limited/noncontact athletes with excellent functional and clinical outcomes, full shoulder range of motion, and a low prevalence of advanced OA at minimum 5 -year follow-up. This modi fi ed technique resulted in a low failure rate in both limited/noncontact and collision/contact athletes. Level of Evidence: Level III, retrospective case control study.
