Abstract
The indication for rotator cuff repair in elderly patients is controversial.
Methods
Consecutive patients over the age of 70 years, under the care of a single surgeon, receiving an arthroscopic rotator cuff repair were reviewed. Predominantly, a single row repair was performed using one (34 cases) or two (30) 5mm Fastin, double-loaded anchors. Double-row repair was performed in four cases. Subacromial decompression and treatment of biceps pathology were performed as necessary.
Data were collected from medical records, digital radiology archives and during clinic appointments. Pain, motion, strength and function were quantified with the Constant-Murley Shoulder Outcome Score, administered pre operatively and at 1-year post operatively. Ultrasound scans were performed at one year to document integrity of the repair.
Results
Sixty-nine arthroscopic cuff repairs were identified in 68 patients. The mean age was 77 years (70–86). The median ASA grade was 2 (79%). The dominant side was operated on in 68% of cases. A range of tear sizes were operated on (5 small, 17 moderate, 29 large and 18 massive). The tendons involved in the tear also varied (supraspinatus 12, supra and infraspinatus 53, supraspinatus and subscapularis 2, supraspinatus infraspinatus and subscapularis 2).
Re-rupture occurred in 20 cases (29%). The mean Constant score increased from 23 (95% CI 19–26) to 59 (54–64) (P< 0.001). Where the repair remained sound, Constant score improved 42 points (95%CI 36–48). If the cuff re-ruptured, constant score also increased on average 12 points (95% CI 2–21). Re-rupture rate was highest for massive cuff repairs: ten out of eighteen (56%).
Conclusion
Arthroscopic rotator cuff repair in the elderly is a successful procedure. Approximately seven out of ten repairs remained intact after one year. Even where re-rupture occurs, a significant improvement in the Constant score was found.
