Superior capsular reconstruction (SCR) is a salvage procedure for massive irreparable rotator cuff tears in patients who are not yet candidates for reverse total shoulder arthroplasty. The procedure replaces the function of the missing rotator cuff with a graft that holds the humeral head down against the glenoid, restoring the joint mechanics that allow the deltoid to elevate the arm.
What Is Superior Capsular Reconstruction?
When a massive rotator cuff tear is irreparable, the humeral head loses its inferior restraint and migrates upward, contacting the acromion. This causes pain, weakness, and inability to elevate the arm. Without a functional rotator cuff to keep the head centered, the deltoid cannot lift the arm effectively.
SCR addresses this by reconstructing the superior capsule with a graft (typically dermal allograft or autograft fascia lata). The graft is anchored to the superior glenoid medially and to the greater tuberosity laterally. It functions as a static restraint that prevents superior migration and re-establishes the fulcrum the deltoid needs to elevate the arm.
Who Is a Candidate?
Candidates for SCR typically have:
- A massive rotator cuff tear that is not repairable due to retraction, fatty atrophy, or chronic disease
- Persistent pain and functional limitation despite non-surgical treatment
- Preserved deltoid function
- An intact subscapularis tendon (or a repairable subscapularis tear)
- Glenohumeral joint without advanced arthritis (rotator cuff arthropathy is treated with reverse arthroplasty instead)
- Younger or active patients for whom reverse arthroplasty would be premature
Patients with rotator cuff arthropathy, advanced glenohumeral arthritis, or pseudoparalysis with arthritis are typically better served by reverse total shoulder arthroplasty.
How the Procedure Is Performed
SCR is performed arthroscopically through standard rotator cuff portals. The joint is examined to confirm that the tear is irreparable. The graft is sized to match the defect and is prepared on the back table.
Suture anchors are placed in the superior glenoid medially. Sutures from these anchors are passed through the medial edge of the graft. Suture anchors are then placed in the greater tuberosity laterally, with sutures passed through the lateral edge of the graft. The graft is shuttled into position through a portal and tensioned, then secured to the bone medially and laterally. Any reparable portion of the rotator cuff (often the anterior cable or remaining subscapularis) is repaired alongside the SCR.
Recovery and Rehabilitation
Recovery follows a protected protocol similar to massive rotator cuff repair:
- Sling protection for six weeks with passive motion within safe limits
- Progressive active motion from six weeks
- Strengthening from three months
- Return to overhead activity at five to six months
- Return to heavy overhead work or sport at nine to 12 months
Risks and Outcomes
Risks include graft failure, persistent pain, infection, and progression to rotator cuff arthropathy. Graft healing depends on tissue quality, surgical technique, and patient compliance with the rehabilitation protocol.
Outcomes in appropriately selected patients are good, with significant pain relief and restoration of active elevation. SCR does not restore strength to the level of a normal rotator cuff but provides a functional improvement that delays or avoids the need for reverse arthroplasty in younger patients.
Why Dr. Chudik for Superior Capsular Reconstruction
Dr. Chudik treats the full spectrum of rotator cuff pathology, including the massive irreparable tears for which SCR is indicated. His arthroscopic experience and high volume of complex shoulder cases inform patient selection: matching SCR to patients who will benefit and recommending alternative procedures (tendon transfer, reverse arthroplasty) when SCR is unlikely to succeed.
