Arthroscopic Capsular Release
This is the standard procedure. Through small incisions, the thickened, contracted capsule is divided under direct vision. The release typically includes the ligaments at the front of the joint, the interval between the rotator cuff tendons at the top, and, when needed, the contracted fold at the bottom of the joint, which is often what limits elevation. Performing the release arthroscopically allows the surgeon to see and control exactly what is divided, which is its principal advantage.
The extent of the release is tailored to the pattern of motion loss. A patient whose main deficit is outward rotation with the arm at the side needs the front of the capsule addressed; a patient who cannot elevate needs the bottom of the capsule released. Dr. Rynecki Baker plans the release from the specific directions of motion that are restricted, measured before surgery and confirmed under anesthesia.
The procedure is performed as an outpatient operation, and a regional nerve block is commonly used, both for comfort and because good pain control in the first days is what allows the motion gained in the operating room to be maintained.
Manipulation Under Anesthesia
With the patient asleep and the muscles relaxed, the shoulder is moved through its range to tear the contracted capsule. It is usually combined with an arthroscopic release; the concern with manipulation alone is that the tissue tears where it will rather than where it is chosen, and fracture of the upper arm bone, injury to the labrum or rotator cuff, and nerve injury are recognized considerations, particularly in patients with osteoporosis. For this reason a controlled arthroscopic release, with or without a gentle manipulation afterward, is generally preferred.
Release with Treatment of Associated Pathology
When stiffness accompanies a rotator cuff tear or follows previous surgery, the release is performed alongside treatment of the underlying problem. Sequencing matters: the release is performed first so that motion is restored, and the repair is protected afterward. When a cuff repair is performed at the same time, the rehabilitation must balance protecting the repair against preserving the motion just gained, and this balance is discussed with the patient and the therapist in advance.
