How Long Is a Rotator Cuff Surgery?

Surgical Techniques: Minimally Invasive Arthroscopy Versus Open Repair

The rotator cuff is an anatomical group of four stabilizing shoulder tendons (supraspinatus, infraspinatus, teres minor, and subscapularis) that hold the humeral head firmly within the shallow glenoid socket. When acute trauma or chronic wear causes these tendons to tear away from the humerus bone, orthopedic shoulder surgeons perform surgical repair to re-anchor the tendon back onto the bone.

Over ninety percent of modern rotator cuff repairs are performed using minimally invasive shoulder arthroscopy. Utilizing pencil-sized cameras (arthroscopes) and miniature surgical instruments inserted through tiny keyhole incisions, surgeons insert specialized bio-absorbable suture anchors into the humerus bone and tie high-strength suture knots to compress the torn tendon back into place without cutting large shoulder muscles.

Comparing surgical methodologies, incision sizes, and typical operating times outlines what patients can expect below.

Operating Room Timeline: Anesthesia, Nerve Blocks, and Anchors

The surgical procedure begins with patient positioning and anesthesia. Most rotator cuff surgeries are performed under a combination of general anesthesia and an interscalene brachial plexus nerve block. Anesthesiologists use real-time ultrasound guidance to inject long-acting local numbing medication around the nerve bundle in the neck. This nerve block provides twelve to twenty-four hours of profound post-operative pain relief, allowing patients to wake up comfortably without severe agony.

Once in the operating room, the patient is placed in either the beach chair position (semi-reclined sitting up) or the lateral decubitus position (lying on the non-injured side with the arm suspended in traction). The surgeon makes two to four microscopic stab incisions (portals) around the shoulder. Sterile saline fluid is pumped into the joint to inflate the space, providing crystal-clear visualization through the high-definition arthroscopic video camera.

A standard outpatient rotator cuff repair follows a structured clinical schedule from arrival to discharge below.

Tear Severity Classifications: Partial, Full-Thickness, and Massive

The surgeon first performs a diagnostic sweep of the joint. If bone spurs on the underside of the acromion bone are pinching the tendon (impingement), the surgeon uses a high-speed motorized burr to shave down the bone (subacromial decompression). If the long head of the biceps tendon is frayed or unstable, a biceps tenodesis is performed, clipping the tendon and anchoring it lower on the arm bone, which adds fifteen to twenty minutes to the surgery.

Tendon re-anchoring represents the core technical feat. The surgeon prepares the bone bed on the greater tuberosity of the humerus, gently decorticating the surface to encourage bone marrow bleeding and biological healing. Small threaded or press-fit anchors made of titanium, PEEK polymer, or biocomposite material pre-loaded with ultra-high-molecular-weight polyethylene sutures are screwed into the bone. Suture needles pass through the torn tendon, pulling it firmly back down against the bone.

After the sutures are tied, the joint is flushed, incisions are closed with tiny nylon stitches or sterile adhesive tape, and waterproof dressings are applied. The patient arm is immediately placed into an abduction pillow sling, which supports the arm away from the body to relieve tension on the newly repaired tendon. Patients are discharged home the same day, embarking on a multi-month physical therapy rehabilitation protocol.
