It is not clear how frozen shoulder is caused even if it is classified as idiopathic, traumatic and diabetics. However frozen shoulder reveals night pain besides shoulder contracture. We focused on the incomplete rotator cuff tear to analyze how night pain occured. We investigated the clinical finding if an arthroscopic cuff repair of incomplete cuff tear was needed to relieve night pain of frozen shoulder. Arthroscopic capsular release was undertaken for the 33 patients of frozen shoulder with an incomplete rotator cuff tear. We separated it into group A (arthroscopic subacromial decompression and arthroscopic capsular release, n=15, average 56.7 years old) and group B (arthroscopic subacromial decompression, margin convergence and arthroscopic capsular release, n=18, average 59.2 years old). The mean period after surgery was 14 months. We released the anterior capsule with VAPR and the lasp was always used for Bankart repair. We analyzed the JOA scores and night pain before and after arthroscopic capsular release in two groups. The JOA score had increased from 44.3 to 80.3 in group A. The JOA score had increased from 45.6 to 92.5 in group B. Night pain had improved in 62% patients of group A, and in 84% in group B. Only ASD and capsular release were not sufficient to improve night pain. Repair of an incomplete rotator cuff tear was useful to improve night pain for frozen shoulder by arthroscopic capsular release.
