title: Arthroscopic observations before and after manipulation of frozen shoulder.
abstract: The purpose of this article is to report the arthroscopic findings before and immediately after manipulation for frozen shoulder. Twenty patients were selected for manipulation under general anesthesia after failing to improve with conservative measures in 6 months. The findings showed the joint capsule was difficult to penetrate with the arthroscope cannula and obturator because of the thickness of the capsular tissue. The glenohumeral joint accepted less than the normal amount of fluid. The humeral head was tight against the glenoid even in the suspended position. The main intraarticular finding was vascular synovitis. There were no intraarticular adhesions or degenerative changes. An immediate postmanipulation second-look arthroscopy showed there was synovial and capsular hemorrhage indicative of tearing from the manipulation. After glenohumeral manipulation, the joint accepted more fluid, and the humerus was easily distracted away from the glenoid with intraarticular distention.
