The long head of the biceps tendon has been proposed as a source of pain in patients with rotator cuff tears. The purpose of this study is to evaluate the objective, subjective, and radiographic results of arthroscopic biceps tenotomy in selected patients with rotator cuff tears. Three hundred seven arthroscopic biceps tenotomies were performed in patients with full thickness rotator cuff tears. All patients had previously failed appropriate nonoperative management. Patients were selected for arthroscopic tenotomy if the tear was thought to be irreparable or the patient was older and not willing to participate in the rehabilitation required following rotator cuff repair. One hundred eleven shoulders underwent a concomitant acromioplasty. The mean age at surgery was 64.3 years. The mean preoperative radiographic acromiohumeral interval measured 6.6 mm. Patients were evaluated clinically and radiographically at a mean 57 months follow-up (range 24 to 168 months). The mean Constant score increased from 48.4 points preoperatively to 67.6 points postoperatively (p < 0.0001). Eighty-seven percent of patients were satisfied or very satisfied with the result. Nine patients underwent an additional surgical procedure (three for attempt at rotator cuff repair and six for reverse prostheses for cuff tear arthropathy). The acromiohumeral interval decreased by a mean

1.3 mm during the follow-up period and was associated with longer duration of follow-up (p < 0.0001). Preoperatively, 38% of patients had glenohumeral arthritis; postoperatively, 67% of patients had glenohumeral arthritis. Concomitant acromioplasty was statistically associated with better subjective and objective results only in patients with an acromiohumeral distance greater than 6 mm. Fatty infiltration of the rotator cuff musculature had a negative influence on both the functional and radiographic results (p < 0.0001). Arthroscopic biceps tenotomy in the treatment of rotator cuff tears in selected patients yields good objective improvement and a high degree of patient satisfaction. Despite these improvements, arthroscopic tenotomy does not appear to alter the progressive radiographic changes that occur with long standing rotator cuff tears.

Background: Rotator cuff tears involving the subscapularis are less common than those involving the posterior superior rotator cuff. The purpose of this study is to report the results of repair of isolated tears of the subscapularis.

Methods: Eighty-four shoulders that had undergone open repair of the subscapularis tendon were reviewed. The mean age at surgery was 53.2 years. The mean interval from onset of symptoms to surgery was 12.5 months. Fifty-seven tears were traumatic, and twenty-seven were degenerative in etiology. Twenty-three of the tears involved the superior third of the subscapularis tendon, forty-one involved the superior two thirds, and twenty were complete tears. Fifty-four shoulders had a dislocation or subluxation of the long head of the biceps tendon, while ten shoulders had a rupture of the long head of the biceps tendon. Forty-eight shoulders underwent concomitant biceps tenodesis; thirteen shoulders underwent concomitant biceps tenotomy; and four shoulders underwent concomitant recentering of the biceps. Patients were evaluated clinically and radiographically at a mean fortyfive month follow-up (range 24 to 132 months).

Results: The mean Constant score increased from 55.0 points preoperatively to 79.5 points postoperatively (p< 0.001). Seventy-five patients were satisfied or very satisfied with the result. Preoperatively, four patients had mild glenohumeral arthritis. Postoperatively, twenty-five patients had mild glenohumeral arthritis and two patients had moderate glenohumeral arthritis. Tenodesis or tenotomy of the biceps tendon at the time of subscapularis repair was associated with improved subjective and objective results independent of the preoperative condition of the biceps tendon.
