Massive or Irreparable Rotator Cuff Tear

Massive does not always mean irreparable

A large tear may still be mobilized and repaired, especially when the injury is recent and the muscles remain healthy. A smaller chronic tear may be irreparable because the tendon has retracted, the tissue has deteriorated, or the muscle has developed advanced atrophy and fatty change. Imaging provides important information, but the final repairability of the tendon may not be known until it is carefully released and evaluated during surgery. A responsible surgical plan includes alternatives in case the tissue cannot support the originally intended repair.

Symptoms and evaluation

Patients may experience night pain, weakness, loss of endurance, difficulty lifting or rotating the arm, and inability to reach a shelf or perform personal care. Some retain useful motion despite a very large tear. Others can no longer actively raise the arm even though the shoulder can be moved passively. Evaluation includes the history, physical examination, shoulder X-rays, and MRI. The MRI assesses tendon retraction, muscle atrophy, fatty degeneration, biceps disease, and other damage. CT may be used when arthritis, bone loss, or reverse replacement is being considered. Deltoid and nerve function are particularly important when active elevation is severely limited.

Treatment options

Nonsurgical treatment may include activity modification, appropriate medication, and therapy focused on the deltoid, remaining rotator cuff, and shoulder-blade muscles. A carefully selected corticosteroid injection may provide temporary pain relief, but repeated injections are approached cautiously when tendon surgery may be considered. Surgical options depend on the anatomy. They may include complete repair, partial repair, graft or biologic augmentation, treatment of the biceps, selected tendon transfer, or another joint-preserving procedure. These operations generally require preserved cartilage, functional surrounding muscles, suitable anatomy, and a patient able to complete prolonged rehabilitation.

When reverse shoulder replacement is considered

Reverse shoulder replacement may provide more predictable elevation and pain relief when an irreparable tear causes major functional loss, particularly when rotator cuff tear arthropathy, pseudoparalysis, substantial bone deformity, or failed prior repair is present. The choice is not simply between "repair" and "replacement." Dr. Knudsen explains what each strategy is intended to accomplish, how long rehabilitation will take, what tissues must heal, and what limitations may remain.

Recovery and realistic goals

Recovery varies widely. Tendon repair and reconstruction require months of protection and rehabilitation while tissue heals. Joint-preserving procedures can maintain the native joint but may have less predictable healing in poor-quality tissue. Reverse replacement follows a different recovery pathway and introduces implant-related long-term considerations. The goal is not the largest or newest operation. It is the treatment most likely to deliver meaningful, durable improvement for the individual's shoulder and priorities.
