The rotator cuff is a group of four muscles and tendons that work together to hold your shoulder joint in place and allow it to move in many directions. These muscles are the supraspinatus, infraspinatus, teres minor, and subscapularis. When one or more of these tendons tear, you have a rotator cuff injury. This guide provides information about how rotator cuff surgery works and what to expect during the process.

Rotator cuff tears are common, especially as people age. Research shows that about 20% of people over age 60 have a rotator cuff tear, even if they don't have symptoms. Tears can happen suddenly from an injury or develop slowly over time from wear and tear. Some people feel pain and weakness in the shoulder, while others notice they cannot lift their arm or sleep on the affected side.
Doctors typically start by trying non-surgical treatments first. These may include rest, ice, anti-inflammatory medications, physical therapy, and corticosteroid injections. Many people recover with these methods alone. However, if symptoms don't improve after several weeks or months of conservative treatment, or if the tear is large and causing significant weakness, surgery may become an option to discuss with your doctor.
The decision to have surgery depends on several factors. Your age, overall health, the size and location of the tear, how long you've had symptoms, and how much the injury affects your daily activities all matter. A surgeon will review imaging tests like MRI or ultrasound to see the exact damage. They will also consider whether you need your shoulder to function at a high level for work or sports.
Practical Takeaway: Understanding that rotator cuff injuries range from minor to severe helps you see why your doctor might recommend surgery only after other treatments haven't worked. Keep a record of your symptoms and how they affect your daily activities to share with your healthcare team.
Before rotator cuff surgery, your doctor performs a thorough evaluation to make sure surgery is the right choice and that you're healthy enough for the procedure. This evaluation includes a physical exam, imaging studies, and blood work. The physical exam typically involves specific shoulder movements and strength tests. Your doctor will check how far you can move your arm, whether certain movements cause pain, and how weak the affected muscles are.

Imaging tests are a critical part of the evaluation. An MRI (magnetic resonance imaging) scan creates detailed pictures of your soft tissues, including the tendons and muscles of your rotator cuff. Ultrasound is another option that uses sound waves to show the tear. X-rays help your doctor see if there are bone spurs or arthritis in the shoulder joint, which might affect the surgery plan. Some doctors use CT scans for more detailed bone information.
Your surgeon will want to know your complete medical history. This includes any previous shoulder injuries, other joint problems, and any surgeries you've had. Tell your doctor about all medications you take, including over-the-counter pain relievers, supplements, and blood thinners. Smoking and certain medications can affect healing, so your doctor may ask you to stop or adjust them before surgery.
Blood tests check your overall health and make sure your blood can clot properly. Your doctor may also want to know about your heart and lung health, especially if you have diabetes, high blood pressure, or other chronic conditions. An anesthesiologist will review your medical history to plan what type of anesthesia is safest for you. This could be general anesthesia (where you're asleep) or regional anesthesia (where your arm and shoulder area is numbed).
Practical Takeaway: Write down a complete list of all medications, supplements, and health conditions before your pre-surgery appointment. Bring this list with you so your surgical team has accurate information for planning your procedure.
Several surgical techniques can repair a rotator cuff tear. The main approaches differ in how the surgeon accesses the shoulder and how they reattach the tendon to the bone. Understanding these options helps you know what to expect on surgery day and during recovery.

Arthroscopic repair is the most common approach today. The surgeon makes two to three small cuts, each about a quarter-inch long. A camera called an arthroscope goes through one cut so the surgeon can see inside the joint. Tiny instruments go through the other cuts to remove damaged tissue and repair the tear. The surgeon may use small anchors with sutures to reattach the tendon to the bone. Arthroscopic surgery causes less tissue damage, reduces pain after surgery, and typically allows faster recovery than open surgery. Most rotator cuff repairs can be done this way if the tear isn't too large or complex.
Mini-open repair uses a slightly larger cut, usually about one to two inches long. This approach is sometimes used when the tear is larger or in a location that's harder to reach with an arthroscope. The surgeon can see the area directly while still causing less tissue damage than traditional open surgery. Mini-open repair may mean a slightly longer recovery than arthroscopic repair but usually faster than full open surgery.
Open repair involves a larger cut, typically three to four inches long. The surgeon can directly see and access the entire shoulder joint. This approach is less common now because arthroscopic techniques have improved, but it may be necessary for very large tears, complex repairs, or if previous surgeries didn't work. Open surgery causes more tissue damage and typically requires a longer recovery period of four to six months.
Some patients with very large tears that cannot be repaired may have a different procedure called a reverse shoulder arthroplasty. Instead of repairing the torn tendon, the surgeon replaces the shoulder joint and reverses its mechanics so other muscles can help move the arm. This is typically only recommended when the rotator cuff is severely damaged and cannot be repaired.
Practical Takeaway: Ask your surgeon which approach they plan to use and why it's best for your specific tear. Understanding the difference between arthroscopic, mini-open, and open procedures helps you prepare mentally and physically for recovery.
On surgery day, you'll arrive at the surgical facility early, usually one to two hours before the procedure. You'll check in, and nursing staff will verify your identity and review your medical history again. They'll place an IV line in your arm for fluids and medication. You'll change into a surgical gown and speak with the anesthesiologist about the anesthesia plan. It's normal to feel nervous—this is a common experience, and the surgical team is trained to keep you comfortable.

You'll be moved to the operating room where the surgical staff prepares you. They'll place monitors on your chest to watch your heart rate, blood pressure, and oxygen levels throughout the surgery. Depending on your anesthesia type, you may feel drowsy and then wake up after surgery with no memory of the procedure, or you may receive regional anesthesia where your shoulder area is numbed but you remain awake (though often lightly sedated).
Once you're asleep or numb, the surgical team cleans your shoulder with an antiseptic solution and drapes sterile cloths around the area. For arthroscopic repair, the surgeon makes small cuts and inserts the camera first. They pump a saline solution into the joint to expand it and see better. The surgeon examines the tear, removes any loose pieces of tendon, and cleans away any bone spurs or inflamed tissue. They then position the torn tendon back onto the bone and secure it with anchors and sutures. This is often called "footprint restoration" because the goal is to restore the tendon to its original attachment point.
The actual repair usually takes 30 to 60 minutes, though the entire time in the operating room is typically two to three hours when you include preparation and closing. Once the repair is complete, the surgeon removes the instruments and camera, drains the saline solution from the joint, and closes the small cuts with sutures or surgical tape. Your shoulder may be placed in a sling before you wake up.
Practical Takeaway: Plan for someone to drive you home and stay with you for at least the first night after surgery. You'll be groggy from anesthesia, and the pain medication may make it unsafe for you to drive or care for yourself immediately after the procedure.
