Failed Rotator Cuff Repair

A failed repair is not defined by MRI alone

Some repaired tendons do not heal completely yet cause little pain and acceptable function. Other patients remain substantially limited even when imaging suggests the tendon is intact. The central question is whether the structural finding explains the patient's symptoms and whether a correctable problem remains. A tear that never healed may require a different strategy than a tendon that healed and later tore after a new injury. The number of prior operations, tendon mobility, muscle quality, arthritis, bone stock, stiffness, and current function all influence the available choices.

Evaluation

Dr. Knudsen reviews the original operative report, arthroscopic photographs, implant or anchor information, preoperative and postoperative imaging, therapy records, and the timeline of recovery. The examination evaluates motion, cuff and deltoid strength, biceps symptoms, stability, scapular mechanics, nerve function, and the cervical spine when appropriate. New X-rays are usually obtained. MRI or ultrasound assesses tendon continuity, retraction, muscle atrophy, fatty degeneration, and associated pathology. CT may be useful for anchor-related bone loss, arthritis, fracture, or planning of replacement. Laboratory testing and aspiration may be necessary when infection is possible.

Treatment options

Treatment may begin with additional rehabilitation when stiffness, strength, endurance, or shoulder mechanics remain modifiable. Injections are used selectively because repeated corticosteroid exposure may be undesirable when further tendon surgery is being considered. Revision repair may be appropriate when the tendon can be mobilized, the muscle remains functional, and the patient can complete a prolonged rehabilitation program. Depending on the tissue, surgery may include arthroscopic or open revision repair, removal or management of prior anchors, graft augmentation, partial repair, biceps treatment, or another joint-preserving reconstruction.

When the tendon is no longer repairable

If the tendon is irreparable, options depend on arthritis, active motion, age, deltoid function, and goals. Selected patients with preserved cartilage may be candidates for tendon transfer or another joint-preserving strategy. Reverse shoulder replacement may be more reliable when there is substantial loss of elevation, advanced cuff tear arthropathy, poor tissue quality, or multiple failed repairs. There is no single operation for every failed repair. Dr. Knudsen discusses the likely benefit, healing potential, rehabilitation, and contingency plan before another surgery is chosen.

Recovery and expectations

Revision tendon surgery generally has a less favorable healing environment than a first-time repair because of scar tissue, reduced tendon mobility, muscle degeneration, and previous fixation. Rehabilitation is often deliberate and prolonged. The objective is not simply to make the MRI look better. It is to reduce pain and improve the strength and function that matter to the patient while avoiding an operation unlikely to deliver sufficient benefit.
