Combined Single Anchor Fixation of Subscapularis and Biceps Pathology Leads to Improved Clinical Outcomes.

Upper-edge subscapularis tendon tears associated with biceps instability are a cause of anterior shoulder pain and disability. At shoulder arthroscopy, the incidence of subscapularis pathology was noted to be 27%, with 47% of these being combined lesions involving the medial reflection pulley. The anatomic location of the upper subscapularis and biceps allows for combined fixation techniques. Arthroscopic subscapularis tendon repair with biceps tenodesis with single-anchor fixation is a cheap and efficient way to address this pathology if biceps tissue quality is sufficient. Careful consideration of surgical technique should lead to improved patient outcomes.
