Objectives: Arthroscopic capsular release in refractory cases of primary frozen shoulder is a well-established and acknowledged procedure with successful outcome. Nonetheless, postoperative limitation of internal rotation is a common complaint that diminishes the postoperative success.

Purpose: The purpose of this prospective study is to assess the results of a new L- shaped arthroscopic posterior capsular release and compare it to the standard longitudinal technique.

Methods: Forty -three consecutive patients with primary frozen shoulder in whom conservative medical, physiotherapy and/or local steroid injection failed to relieve the symptoms were included in the study. Arthroscopic capsular release was performed in all cases. Group 1 had the standard longitudinal anterior and posterior release only; group 2 included an additional L-shaped posterior capsular release. Constant-Murley functional score was used to assess the overall outcome and patient satisfaction.

Results: The mean age of the patients was 49 years (range, 27 to 67 years), with no statistical difference between the 2 groups. There were 22 patients in group 1 and 21 patients in group 2. The mean follow-up period was 34 months (range, 24 to 42 months). At the final follow up, there was a highly significant improvement in Constant score (P < .001) postoperatively in both groups. A similar finding was noted in the overall range of motions (P < .001). However, Group 2 showed significant postoperative difference in the improvement of the internal rotation range of motion.

Conclusion: The L shaped arthroscopic posterior capsular release in patients with primary frozen shoulder is a new technique that significantly improves the postoperative internal rotation range of motion.
