When a tear cannot be brought back to bone, several options restore function without a conventional repair. Which one is appropriate depends on the patient’s age, activity level, which tendons are involved, whether the joint surface is preserved, and whether the subscapularis is intact.
Superior capsular reconstruction
A graft is secured between the top of the socket and the humeral head to restrain upward migration of the ball and restore the mechanics that a missing supraspinatus can no longer provide. This is generally considered in younger patients with a preserved joint surface.
Lower trapezius tendon transfer
For irreparable tears at the back of the rotator cuff, where loss of the infraspinatus leaves a patient unable to rotate the arm outward, the lower trapezius tendon is transferred, typically extended with a graft, to the back of the humerus. Because the lower trapezius pulls in a direction similar to the infraspinatus, the transfer restores active external rotation in a way that reproduces the shoulder’s normal mechanics. It is best suited to younger, active patients with a preserved joint surface and an intact subscapularis.
Biodegradable subacromial spacer
A soft, balloon-shaped implant is placed arthroscopically into the space beneath the acromion and filled with saline, where it acts as a cushion that keeps the humeral head from riding upward and allows the remaining intact tendons to work more efficiently. It dissolves over the course of about a year. The appeal is the recovery: there is no repair or transfer to protect, so the sling period is short and motion begins immediately, which makes it worth considering in older or lower-demand patients who still have reasonable overhead elevation and who want to avoid a larger operation.
Partial repair and debridement
In lower-demand patients whose main complaint is pain rather than weakness, repairing what can be repaired, removing inflamed tissue, and addressing the biceps tendon can provide meaningful relief.
Reverse Total Shoulder Arthroplasty
Reverse shoulder replacement is the procedure for rotator cuff tear arthropathy and for irreparable tears in patients who have lost the ability to lift the arm, particularly older or lower-demand patients and those in whom a tendon transfer or reconstruction is not appropriate.
The operation reverses the anatomy of the joint: a ball is fixed to the socket and a socket to the top of the humerus. This changes the mechanics of the shoulder so that the deltoid, rather than the rotator cuff, elevates the arm. Patients who could not raise the arm before surgery are often able to do so afterward, and the procedure is highly effective for the pain of cuff tear arthropathy.
