Abstract

Background
To compare outcomes of arthroscopic rotator cuff repair with or without repair of partial thickness subscapularis tears.
Patients and Methods
Patients who underwent arthroscopic supraspinatus and/or infraspinatus repair with associated partial thickness tear of the upper subscapularis were included. Patients were categorized into two groups where group 1 underwent debridement of the partial subscapularis tear and group 2 had their subscapularis tendon repaired using a single suture anchor. The minimum follow-up was 24 months. The primary outcome was the modified University of California Los Angeles (UCLA) score.
Results
A total of 52 patients were included (32 in group 1 and 20 in group 2). Both groups had significantly improved total modified UCLA scores at the final follow-up. All components of the modified UCLA score improved in both groups except the range and force of active external rotation. No significant differences were noticed between both groups in terms of gain in clinical and functional outcomes as well as the outcomes at the final follow-up.
Conclusions
Both arthroscopic repair and debridement of partial thickness subscapularis tears seem to achieve favorable and similar outcomes in patients undergoing arthroscopic supraspinatus and/or infraspinatus repair.
