Arthroscopic Arthrolysis for Recalcitrant Frozen Shoulder: Double Posterior Approach.

Arthroscopic capsular release is required in some patients with frozen shoulder (FS). In some cases of recalcitrant FS, arthroscopic capsular release is difficult because of the abnormal narrowing of the joint space. The aim of this article is to introduce an arthroscopic double posterior approach combined with lateral and anterior approaches that is used to complete release of the glenohumeral joint capsule at 360°, subacromial debridement, and long head of biceps tenotomy. This article shows that this double posterior technique is a safe and highly effective totally intra-arthroscopic release technique for recalcitrant FS.
