Purpose: There are few reports in the literature detailing the arthroscopic treatment of multidirectional instability of the shoulder. The purpose of this study was to evaluate the results of arthroscopic methods in the treatment of athletes with symptomatic multidirectional instability of the shoulder. Method: Forty patients (43 shoulders) with multidirectional instability of the shoulder were treated via arthrscopic means and were evaluated at a mean of 33.5 months post-operatively. The mean patient age was 19.1 years (range 14 to 39). There were 24 male patients and 16 female patients. Patients were evaluated with the ASES and WOSI scoring systems. Stability, strength, and range of motion were evaluated with patient-reported scales. Results: The mean ASES score postoperatively was 91.4 out of 100. The mean WOSI post-operative percentage score was 91.1 out of 100. Ninety-one percent of patients had full or satisfactory range of motion, 98% had normal or slightly decreased strength, and 86% of patients were able to return to their sport with little or no limitation. Conclusion: Arthroscopic methods can provide an effective treatment for symptomatic multidirectional instability in an athletic population.
