Arthroscopic pancapsular plication for multidirectional shoulder instability in overhead athletes.
Treating shoulder multidirectional instability with an open stabilization procedure has been reported to have good results. However, few studies exist of arthroscopic plication, especially in overhead athletes. The purpose of this study was to evaluate the clinical outcomes of arthroscopic pancapsular plication for multidirectional instability in overhead athletes.Twenty-three athletes with symptomatic multidirectional instability were treated with arthroscopic pancapsular plication and evaluated at a mean follow-up of 36.3 months (range, 24-61 months). Mean patient age was 23.3 years (range, 19-33 years). Functional outcomes were evaluated with the American Shoulder and Elbow Surgeons (ASES) score, Constant shoulder score, and Rowe instability score. The degree of pain and range of motion were also recorded. All postoperative functional scores were rated good to excellent, with an average ASES score of 88.4 (range, 82-95), average Constant shoulder score of 88.1 (range, 81-100), and average Rowe instability score of 86.7 (range, 80-100). Five patients returned to the same level of competitive sports, and 18 returned to a limited level. All patients were satisfied with the stability postoperatively. No significant change was observed in postoperative range of motion, but patients who returned to a limited level of sports had lower functional scores and more pain than did those who fully returned to sports.Arthroscopic pancapsular plication for treating multidirectional instability in overhead athletes can provide good stability. However, the low rate of return to a full level of overhead sports is a problem. Further evaluation of the benefits of this procedure for overhead athletes with symptomatic multidirectional instability is needed.
