The Role of Superior Capsule Reconstruction in Rotator Cuff Tears.

Massive, irreparable rotator cuff disease is a challenging problem to treat, especially in the younger active patient. This condition allows the deltoid to generate anterosuperior translation and shoulder dysfunction. Ideally, this dysfunction may be improved with rotator cuff repair. However, in the setting of irreparable rotator cuff disease, normal function is challenging to restore. Superior capsule reconstruction theoretically improves function by recentering the humeral head and improving glenohumeral kinematics. This restoration of stability results in a stable fulcrum, and may allow the deltoid and remaining cuff can function more effectively.
