What rotator cuff surgery is and why people have it

Rotator cuff surgery repairs torn tendons in your shoulder that help you lift your arm and rotate it. The rotator cuff is a group of four muscles and their tendons that hold your shoulder joint in place and let you move your arm in almost any direction. When one or more of these tendons tear—from an injury, overuse, or age—the tear can cause pain, weakness, and limited movement.

Not every rotator cuff tear requires surgery. Many people manage tears with physical therapy, rest, and anti-inflammatory medication. Surgery becomes an option when conservative treatment hasn't reduced pain after several months, when the tear is large, when you've lost significant strength, or when the tear happened recently from a clear injury. Your doctor will use imaging tests like MRI or ultrasound to see the size and location of the tear and help decide whether surgery makes sense for your situation.

Key Takeaways

  • Rotator cuff surgery reattaches torn tendons to the bone using sutures and anchors, and is usually done with small incisions (arthroscopic) rather than one large cut.
  • The procedure typically takes one to two hours, and you go home the same day under local or general anesthesia.
  • Recovery involves wearing a sling for four to six weeks, followed by physical therapy that usually lasts three to six months.
  • Most people regain significant strength and pain relief, though full healing can take up to a year and some people never regain complete range of motion.
  • Complications are uncommon but can include infection, re-tearing, and stiffness; your surgeon will discuss your individual risks before the procedure.

How the surgery is performed

Most rotator cuff repairs today use arthroscopic surgery, which means the surgeon makes two or three small cuts (usually less than an inch each) instead of one large incision. A camera called an arthroscope goes through one cut so the surgeon can see inside your shoulder, and surgical instruments go through the other cuts. This approach causes less damage to surrounding tissue, means less pain afterward, and typically allows faster recovery than open surgery.

During the procedure, the surgeon locates the torn tendon and cleans away any damaged tissue. They then reattach the tendon to the bone using sutures (stitches) anchored by small metal or plastic anchors screwed into the bone. The number of anchors depends on the size and location of the tear. Once the tendon is secured, the surgeon checks that the repair is solid by moving your arm through its range of motion, then closes the small cuts with a few stitches.

In some cases—usually when the tear is very large, when there are multiple tears, or when the tendon is severely damaged—your surgeon may recommend open surgery instead. This involves one larger incision, typically four to five inches, which gives the surgeon more direct access and visibility. Open surgery may also be necessary if you've had previous rotator cuff surgery on the same shoulder.

What to expect on surgery day

You will arrive at the surgical center or hospital a couple of hours before your scheduled procedure. A nurse will check your vital signs, review your medical history, and place an IV line. You'll meet with the anesthesiologist, who will discuss whether you'll receive general anesthesia (you'll be asleep) or regional anesthesia (your shoulder area is numbed but you remain awake). Most rotator cuff surgeries use general anesthesia, though some surgeons use a nerve block that numbs just the shoulder.

The surgery itself usually takes one to two hours. Afterward, you'll spend time in the recovery room while the anesthesia wears off. Most people go home the same day, though you'll need someone to drive you because anesthesia affects your alertness and judgment for several hours. Before you leave, the surgical team will give you pain medication, instructions for caring for your incisions, and a sling to wear to protect your shoulder.

The first weeks of recovery at home

Pain and swelling are normal in the first few days after surgery. Ice your shoulder for 15 to 20 minutes at a time, several times a day, to reduce swelling. Keep your arm in the sling most of the time for the first four to six weeks—this protects the repair while the tendon begins to heal to the bone. You can remove the sling to bathe or do gentle exercises your surgeon prescribes, but avoid lifting, pushing, or pulling anything.

Take pain medication as prescribed, especially before physical therapy sessions. Most people need prescription pain relief for the first week or two, then transition to over-the-counter options as pain decreases. Swelling typically peaks around day three or four, then gradually improves. If you notice increasing redness, warmth, drainage from the incisions, or fever, contact your surgeon—these can be signs of infection.

You'll have a follow-up appointment with your surgeon about one to two weeks after surgery to check your incisions and discuss when to start more active physical therapy. At this point, your surgeon will likely clear you to begin pendulum exercises (gentle arm swings) and passive range-of-motion work, where a therapist or your other arm moves your surgical arm without your muscles doing the work.

Physical therapy and returning to normal activity

Physical therapy is crucial to your recovery and typically lasts three to six months. The first phase (weeks one to six) focuses on protecting the repair and preventing stiffness through gentle, passive movements. The second phase (weeks six to twelve) gradually introduces active movements where your muscles do the work, building strength slowly. The third phase (three to six months) emphasizes strengthening and returning to everyday activities.

Your therapist will give you exercises to do at home—usually 15 to 30 minutes daily—in addition to in-clinic sessions. Progress is gradual by design: pushing too hard too fast can re-tear the repair. Most people can return to light activities like desk work or driving within four to six weeks. Returning to sports, heavy lifting, or overhead activities typically takes four to six months or longer, depending on the sport or activity and how well your repair is healing.

Full healing of the tendon to the bone can take up to a year. Even after you feel better and regain strength, your surgeon may recommend continuing some exercises to maintain your shoulder's stability and prevent future injury.

Outcomes and what to realistically expect

Most rotator cuff repairs are successful in terms of the tendon staying attached to the bone. Studies show that 85 to 90 percent of repairs hold without re-tearing, though this varies based on the size of the original tear, your age, and other factors. Most people experience significant pain relief—many report that their pain is gone or much improved within three to six months.

Strength and range of motion improve gradually over the first year. Many people regain near-normal strength, though some never recover complete range of motion, especially overhead movement. This doesn't necessarily mean the surgery failed; it may reflect the extent of the original damage or the body's natural healing limits. Your surgeon can discuss what realistic outcomes look like for your specific tear before surgery.

Age matters: younger people tend to recover faster and more completely than older adults. People over 65 may experience slower progress and slightly higher re-tear rates, but surgery can still provide meaningful pain relief and functional improvement. Pre-existing conditions like diabetes or rheumatoid arthritis can also affect healing speed.

Possible complications and risks

Serious complications from rotator cuff surgery are uncommon, but they do happen. Re-tearing is the most common complication, occurring in 5 to 20 percent of repairs depending on tear size and patient age. A re-tear usually causes pain to return and may require a second surgery. Infection is rare (less than 1 percent) but can occur at the incision sites; signs include increasing redness, warmth, swelling, or drainage. Stiffness can develop if you don't do physical therapy or if scar tissue builds up; this is why consistent therapy is important.

Less common complications include nerve or blood vessel injury during surgery, blood clots, and anesthesia reactions. Your surgeon will discuss your individual risk factors before the procedure—factors like smoking, diabetes, age, and the size of your tear all influence your personal risk profile. Most people who have rotator cuff surgery experience good outcomes with manageable recovery.

Frequently Asked Questions

Can I sleep in my bed normally after surgery?

For the first few weeks, you'll need to sleep with your arm supported by pillows or a wedge pillow to keep your shoulder still and prevent rolling onto it during sleep. Most people sleep in a reclined position or propped up on several pillows rather than flat. Your surgeon will tell you when you can return to normal sleeping positions, usually around four to six weeks.

What if my shoulder feels worse after a few weeks of therapy?

Some increase in soreness after starting therapy is normal as you begin moving the shoulder more. However, sharp pain or sudden loss of motion can signal a problem like re-tearing or excessive inflammation. Contact your surgeon or therapist if pain increases significantly or if you lose motion you previously had. They may adjust your therapy plan or imaging to check the repair.

Will I need surgery on my other shoulder eventually?

Not necessarily. Some people develop rotator cuff tears in both shoulders over time, but many do not. The risk depends on your age, activity level, and whether the original tear was from injury or gradual wear. Your surgeon can discuss your individual risk, but having one shoulder repaired doesn't mean the other will inevitably need surgery.

How much does rotator cuff surgery cost?

Costs vary widely depending on whether you have insurance, your deductible and coverage, whether the surgery is done at a hospital or outpatient center, and your geographic location. If you have insurance, your out-of-pocket cost is typically your deductible plus coinsurance. If you don't have insurance, ask your surgeon's office for a cost estimate before scheduling; many facilities offer payment plans.

Can I avoid surgery with physical therapy alone?

Many rotator cuff tears improve significantly with physical therapy, rest, and anti-inflammatory medication, especially smaller tears or partial tears. However, large tears, tears from acute injury, and tears causing severe weakness or loss of function are less likely to heal without surgery. Your surgeon can discuss whether your specific tear is likely to improve with conservative treatment or whether surgery offers better outcomes.
