Abstract

Objectives: To evaluate the functional outcome of arthroscopic capsular release for treatment of frozen shoulder. Background: Frozen Shoulder is a painful restriction of both active and passive glenohumeral movement. Most impaired directions of motion are flexion, abduction and external rotation. Arthroscopic capsular release treatment of frozen shoulder was found to be safer than open surgical release and manipulation under general anesthesia as it is less probable to cause iatrogenic humeral fracture bone or the rotator cuff tear. Methods: A prospective study on 18 patients with frozen shoulder treated by arthroscopic capsular release. Results: At the end of the follow up, the mean score of external rotation according to the Constant and Murley score was 7.4 ± 2.16, compared to a pre-operative mean of 1.8 ± 1.11, the mean score of active forward flexion was 9.4 ± 0.94, compared to a pre-operative mean of 4 ± 1.45, the mean score of active abduction was 8 ± 0.92, compared to a pre-operative Mean 3.1 ± 1.21,the mean score of strength was 17 ± 5.48, compared to a pre-operative Mean 10.5 ± 5.1. At the end of the follow up period, the mean final score was 80.72 ± 11.16 and all patients achieved excellent score post operatively. Conclusion: Arthroscopic capsular release is an effective and safe method for treatment of refractory cases of frozen shoulder in which other treatment methods failed. It achieved dramatic pain and motion improvement immediately postoperatively, allowing very early postoperative rehabilitation.
