Arthroscopic debridement of massive rotator cuff tears: negative prognostic factors.

Abstract：

INTRODUCTION:The purpose of this study was to identify the factors that may lead to poor outcomes after arthroscopic debridement in massive rotator cuff tears. MATERIALS AND METHODS:Thirty-three patients (10 women and 23 men) with massive, irreparable rotator cuff tears underwent arthroscopy by a single surgeon. The preoperative diagnosis was based on the clinical examination and MRI. Their mean age was 69 years (range 62-79 years), and the average follow-up was 31 months (range 24-46 months). If indicated, the performed arthroscopic debridement included acromioplasty, debridement of the cuff, resection of the distal part of the clavicle or tenotomy of the long head of the biceps. In 28 cases (85%) acromioplasties and in 6 cases (18%) biceps tenotomies were performed, 2 of which were a single tenotomy without any associated acromioplasty. One patient had been managed with concomitant resection of the distal part of the clavicle. RESULTS:The Constant and Murley Score improved by a mean of 30 points, from a mean of 37 points (range 21-52) preoperatively to a mean of 67 points (range 31-82) at the time of follow-up. Some 82% of the patients were satisfied with the procedure. The result was considered unsatisfactory because of inadequate pain relief in 4 shoulders, because of limited active abduction in 1 and because of limited external rotation in 1. A poor outcome was associated with a complete tear of the subscapularis tendon in 6 patients. The radiological study showed no significant narrowing of the subacromial space. CONCLUSION:Our early results suggest that arthroscopic debridement is an excellent treatment for elderly patients with modest functional demands. However, its long-term consequences remain to be evaluated by studies with lengthy follow-up. Prognostic factors that may lead to a negative outcome are preoperative superior migration of the humeral head, presence of subscapularis tear, presence of glenohumeral arthritis and decreased range of motion.
