Subscapularis Tendon Tears: How Best to Approach This Issue.

Subscapularis tears, either in combination with more extensive rotator cuff pathology or in isolation, are a relatively common cause of shoulder pain and dysfunction which often requires surgical intervention. Similar to the general treatment of most rotator cuff tears, patients may respond to conservative treatment and not require surgical intervention, especially in the elderly or those with partial tears. However, many subscapularis tears require intervention to address complaints of pain, dysfunction, or both. The spectrum of subscapularis tears ranges from low-grade partial requiring simple debridement to full-thickness tears which have become retracted and irreparable necessitating complex repair. Although open repair had been performed with success, most subscapularis repairs can be accomplished with arthroscopic techniques.
