Rotator cuff surgery is the repair of inflammation or tears of the rotator cuff tendons in the shoulder. There are four tendons in the rotator cuff, and these tendons are attached individually to the following muscles: teres minor, subscapularis, infraspinatus, and the supraspinatus. The tears and inflammation associated with rotator cuff injury occur in the region near where these tendon/muscle complexes attach to the humerus (upper arm) bone.


Rotator cuff surgery is necessary when chronic shoulder pain associated with rotator cuff injury does not respond to conservative therapy such as rest, heat/ice application, or the use of non-steroidal anti-inflammatory drugs (NSAIDs). Rotator cuff injuries are often lumped into the category referred to as rotator cuff syndrome. Rotator cuff syndrome describes a range of symptoms from basic sprains and tendon swelling (tendonitis) to total rupture or tearing of the tendon.


Approximately 5-10% of the general population is believed to have rotator cuff syndrome at a given time. It is not commonly found in individuals under the age of 20 years, even though many in this population are athletically active. In general, males are more likely than females to develop rotator cuff syndrome and require surgery. Most rotator cuff injuries are

associated with athletic activities such as baseball, tennis, weight lifting, and swimming, where the arms are repeatedly lifted over the head. Rotator cuff injuries can also occur in accidents involving falling to the ground or when the humerus is pushed into the shoulder socket. Rotator cuff injuries can also occur in older, active individuals because the rotator cuff tendons begin to deteriorate after age 40. Occupations that have been associated with rotator cuff injuries include nursing, painting, carpentry, tree pruning, fruit picking, and grocery clerking.


For most patients, if the pain begins to subside, they are encouraged to undergo a period of physical therapy. If the pain does not subside after a few weeks, then the physician may suggest the use of cortisone


Adhesions— A fibrous band that holds together tissue that are usually separated and that are associated with wound healing.

Arthrography— Visualization of a joint by radiographic means following injection of a contrast dye into the joint space.

Arthroscope— An endoscope, or a tube containing an optical system, that is used to examine the interior of a joint.

Bone spurs— A sharp or pointed calcified projection.

Bursa— A sac found in connective tissue that acts to reduce friction between tendon and bone.

Deltoid muscle— Muscle that covers the prominence of the shoulder.

injections into the shoulder region. Rotator cuff repair is then considered if the more conservative methods are not successful.

The primary aim of rotator cuff repair is to repair the connection between the damaged tendon and the bone. Once this bridge is re-established and the connection between the tendon and the bone has thoroughly healed, the corresponding muscles can once again move the arm in a normal fashion. The goal of the surgery is to ensure the smooth movement of the rotator cuff tendons and bursa under the upper part of the shoulder blade. The surgery is also performed to improve the comfort of the patient and to normalize the function of the shoulder and arm. There are a variety of surgical approaches that can be used to accomplish rotator cuff repair. The most common approach is called the anterior acromioplasty approach. This approach allows for excellent access to the most common sites of tears—the biceps groove, anterior cuff, and the undersurface of the joint.

Three types of rotator cuff repair surgeries are performed: open incision, mini-open incision, and arthroscopic. Most rotator cuff repairs are accomplished using incisions that minimize cosmetic changes in the skin following healing. If possible, the surgery is performed with an arthroscope to minimize cosmetic damage to the skin. Typically, the incision made is about the size of a buttonhole. The arthroscope, a pencil-sized instrument, is then inserted into the joint. The surgeon usually accesses the rotator cuff by opening part of the deltoid muscle. If bone spurs, adhesions, and damaged bursa are present in the


Rotator cuff repair is generally performed by a specialist known as an orthopedic surgeon, who has received specialized training in the diseases and injuries of the musculoskeletal system. Orthopedic surgeons who performs rotator cuff repair receive extensive training in general surgery and in the specific techniques involving the musculoskeletal system. Rotator cuff repairs are often performed in the specialized department of a general hospital, but they are also performed in specialized orthopedic surgery clinics or institutes for orthopedic conditions.

rotator cuff region, then the surgeon will generally remove these damaged structures to improve function in the joint. In cases where the arthroscopic technique is not advised or when it fails to achieve the desired results, a conversion to open surgery is made. This involves a larger incision and usually requires more extensive anesthesia and a longer recovery period.

The success of the rotator cuff repair is dependent on the following factors:

  • age of the patient
  • type of surgical technique employed
  • degree of damage present
  • patient’s recovery goals
  • patient’s ability to follow a physical therapy program following surgery
  • smoking status
  • number of previous cortisone injections


The diagnosis of rotator cuff injury is based on a combination of clinical signs and symptoms, coupled with diagnostic testing. The most common clinical signs and symptoms include:

  • tenderness in the rotator cuff
  • pain associated with the movement of the arm above the head
  • pain that is fairly constant but more intense at night
  • weakness or pain with the forward movement of the arm
  • muscle atrophy (wasting) in long-term injuries that involve a complete tendon tear

  • Is surgery the answer for me?
  • Can you recommend a surgeon who performs rotator cuff repairs?
  • If surgery is appropriate for me, what are the next steps?

X rays are used to rule out other types of injuries or abnormalities present in the shoulder region. While x rays are often used to help solidify the diagnosis, arthrography, ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI) are the definitive tests in the diagnosis of rotator cuff injury. Arthography and ultrasonography of the shoulder can help determine whether or not there is a full tear in the rotator cuff. A MRI can help determine whether there is a full tear, partial tear, chronic tendonitis, or other cause of the shoulder pain. The final decision to repair the tear ultimately rests on the amount of pain and restriction suffered by the patient.


Following the procedure, the patient will typically spend several hours in the recovery room. Generally, an ice pack will be applied to the affected shoulder joint for a period up to 48 hours. The patient will usually be given either prescription or non-prescription pain medication. The dressing is usually removed the day after surgery and is replaced by adhesive strips. The patient should contact a physician if there are any significant changes in the affected area once the patient goes home. These changes can include increased swelling, pain, bleeding, drainage in the affected area, nausea, vomiting, or signs of infection. Signs of infection include fever, dizziness, headache, and muscle aches.

It often takes several days for the arthroscopic puncture wounds to heal, and the joint usually takes several weeks to recover. Most patients can resume normal daily activities, with the permission of a physician, within a few days following the procedure. Most patients are advised to undergo a rehabilitation program that includes physical therapy. Such a program can facilitate recovery and improve the functioning of the joint in the future.

Complications following arthroscopic rotator cuff surgery are very rare. Such complications occur in less than 1% of cases. These complications include instrument breakage, blood vessel or nerve damage, blood vessel clots, infection, and inflammation. Complications, though still rare, are more common following open surgery. This is due to the larger incisions and more complicated anesthesia that is often necessary.

Normal results

The prognosis for the long-term relief from rotator cuff syndrome is good, especially when both conservative and surgical therapeutic approaches are used. In those patients who do require surgery, six weeks of physical therapy is typically instituted following surgery. Complete recovery following surgery may take several months. In rare cases, the rotator cuff injury is so severe that the patient may require muscle transfers and tendon grafts. Even more rarely, the injury can be so severe that the tendons are not repairable. This typically occurs when a severe rotator cuff injury is neglected for a long period of time.

Morbidity and mortality rates

Morbidity is rare in both the arthroscopic and open procedures. Mortality is exceedingly rare in patients undergoing rotator cuff repair.


Conservative approaches are typically used before surgery is considered in patients with rotator cuff injury. This is true even in cases where there is evidence of a full tendon tear. Some patients with a full or partial tear do not suffer a significant amount of pain and retain normal or nearly normal range of motion in shoulder movement. A majority of those with rotator cuff syndrome respond to conservative non-surgical approaches. Conservative therapies include the following:

  • heat or ice to reduce pain and swelling
  • cessation or reduction of activities that involve the movement of the arms overhead
  • medication such as non-steroidal anti-inflammatory agents to reduce pain and inflammation
  • cortisone injections to reduce pain and inflammation
  • rest

Once the pain begins to subside, the patient usually is encouraged to begin a program of physical therapy to help re-institute normal motion and function to the shoulder.
