Abstract
Purpose
We evaluated the functional and radiological outcomes of arthroscopic trans-tendon suture-bridge repair for partial-thickness articular-side rotator cuff tears.
Methods
From December 2008 to May 2010, 32 consecutive patients with partial-thickness articular-side rotator cuff tears prospectively underwent arthroscopic trans-tendon suture-bridge repair. We included patients with articular-side partial-thickness supraspinatus tears involving more than half the normal thickness. Patients underwent ultrasonography or magnetic resonance imaging postoperatively. The functional outcomes of patients were evaluated at a minimum 1 year postoperatively. The mean age and follow-up period for the patients were 51.8 ± 13.7 years and 17.4 ± 4.2 months, respectively. Five outcome measures were used before surgery and at the final follow-up: a visual analog scale (VAS) pain score, the American Shoulder and Elbow Surgeons (ASES) score, the Shoulder Rating Scale of the University of California at Los Angeles (UCLA), the Constant–Murley score and range of motion (ROM).
Results
The radiological follow-up rate was 87.5 %, and the follow-up rate for clinical evaluation was 96.9 %. Mean UCLA, ASES and Constant–Murley scores improved from 19.1 ± 5.4, 45.2 ± 16.0 and 58.0 ± 19.6 preoperatively to 35.7 ± 8.5, 79.0 ± 15.8 and 78.1 ± 12.9 at final follow-up, respectively (all p ≤ 0.001). Mean VAS score and ROM (forward flexion) improved from 6.1 ± 1.9 and 140 ± 36.6 preoperatively to 2.6 ± 1.9 and 163 ± 25.2 at the final follow-up, respectively (p ≤ 0.001). Additionally, the postoperative radiological examination showed cuff integrity without retear in all patients.
Conclusions
Arthroscopic trans-tendon suture-bridge repair for partial-thickness articular-side rotator cuff tears resulted in significant improvement in function compared with that before the operation.
