Shoulder function after surgical repair of rotator cuff tears.

Shoulder function was assessed in 37 patients with a mean age of 57 years after acromioplasty and repair of full-thickness rotator cuff tears were performed. The cuff tears were closed without transfer of other muscles or use of synthetic materials. At review 2 years after surgery 32 patients had significant pain relief and improved shoulder function. Range of motion, muscle strength, and endurance were increased. The mean Constant score was 77, and 80% of the patients were graded as having mild or disability. Radiographic measurements disclosed an increased supraspinatus outlet area after surgery. It is concluded that in patients with impingement syndrome and a full-thickness rotator cuff tear, shoulder function will be improved after acromioplasty and cuff repair, but a slight decrease in range of motion and muscle strength will remain when compared with the contralateral side.
