There are few reports of arthroscopic revision cuff repair. The purpose of this study is to evaluate the clinical outcome for arthroscopic revision cuff repair. We treated 13 patients with arthroscopic revision cuff repair. The cases were 11 male and 2 female, with an average age of 62.3 years old. The mean follow up period was 20 months. The duration from initial operation to revision surgery ranged from 30 months. 3 shoulders had middle rotator cuff tear, 6 shoulders had massive rotator cuff tear and 4 shoulders had global rotator cuff tears. 9 shoulders were treated by primary repair and 4 shoulders were treated by fascia lata graft. Clinical results were evaluated according to the Japanese Orthopaedic Association score (JOA score). Cuff integrity was evaluated by MRI. The average postoperative JOA score improved from 46.3 to 72.1. There was no significant correlation between initial operation (open or arthroscopic). There was a correlation between postoperative JOA score and duration from initial operation to revision surgery. Poor result cases were caused by limitation of range of motion and loss of muscle strength. Re-tear of rotator cuff identified by MRI were 3 cases. The clinical outcome for arthroscopic revision cuff repair was mostly satisfactory, but we must be careful for indication.
