title: Partial thickness rotator cuff tears: results of arthroscopic treatment.
abstract: Thirty-one patients with arthroscopically documented partial thickness rotator cuff tears treated by arthroscopic debridement of the lesion were retrospectively reviewed. The patients had had symptoms for an average of 20.5 months prior to surgery. Twenty-two of these 31 shoulders also had bursoscopy, with 18 having arthroscopic subacromial decompression. The results were graded by both the UCLA Shoulder Rating Scale and Neer's criteria. Twenty-six (84%) of the patients had satisfactory results with the remaining 5 (16%) patients having unsatisfactory results. A classification system for the size and location of partial thickness rotator cuff tears is presented. The lesion size did not affect the result. Repeat arthroscopy in three patients demonstrated no further deterioration of their rotator cuff. The results with and without subacromial decompression were similar. The need for subacromial decompression is best determined by the arthroscopic finding of a bursal side tear.
