In a complete tear, the tendon pulls away from its attachment on the humerus, preventing the muscle from properly stabilizing and moving the shoulder. Over time, the tendon may retract and surrounding muscles can weaken, which can make treatment more complex if the condition is not addressed early.
Treatment often begins with conservative care focused on reducing pain and maintaining mobility. This may include activity modification, anti-inflammatory medications, and guided physical therapy to strengthen surrounding muscles. Corticosteroid injections may also be used to help control inflammation.
If symptoms persist or strength and function are significantly affected, surgical repair may be recommended. Arthroscopic techniques are commonly used to reattach the tendon to the bone, followed by a structured rehabilitation program to restore motion and strength.
Common Causes
Complete rotator cuff tears may occur from either acute injury or gradual degeneration of the tendon. Traumatic tears often happen during events such as falling on an outstretched arm, lifting something heavy, or experiencing a sudden pulling force on the shoulder.
Degenerative tears are more common and develop slowly as tendons weaken over time. Repetitive overhead motion in sports like baseball, tennis, or swimming can contribute to tendon stress. Occupations involving frequent lifting or overhead work may also increase risk. In addition, bone spurs that form under the acromion can rub against the tendons, gradually contributing to tendon damage.
Common Symptoms
A complete rotator cuff tear often causes persistent shoulder pain and noticeable weakness in the arm. Many patients experience difficulty lifting the arm overhead or reaching away from the body. Pain may radiate from the shoulder down the upper arm and often becomes worse with activity.
Night pain is also common, particularly when lying on the affected shoulder. Some individuals notice clicking, popping, or grinding sensations during movement. As the condition progresses, everyday tasks such as dressing, reaching for objects, or lifting items may become increasingly difficult. Early evaluation can help determine the severity of the injury and guide the most appropriate treatment plan.

Three Common Treatments
Conservative Care
Rest, limiting overhead activities, taking anti-inflammatory medications, and engaging in a physical therapy program to stretch the shoulder and strengthen surrounding muscles often relieve pain and improve functionality without surgery.
Corticosteroid Injection
A steroid injection into the shoulder reduces inflammation and pain for many patients. This may make it easier to do therapy and everyday tasks, but the benefits are often temporary, so injections are used carefully.
Surgical Repair
Arthroscopic or mini-open surgery reattaches the torn tendon to the humerus using sutures and anchors. Surgery is recommended for persistent pain, large tears, or significant weakness and is followed by a structured rehabilitation program.
Frequently Asked Questions
What causes a complete rotator cuff tear?
A complete rotator cuff tear can develop either gradually or suddenly. Degenerative tears are more common and occur over time as the tendon weakens with age, repetitive overhead motion, or reduced blood supply. Activities such as painting, lifting, or sports like tennis and baseball can place ongoing stress on the tendon.
Acute tears, on the other hand, happen suddenly due to trauma, such as a fall on an outstretched arm, lifting a heavy object, or a shoulder dislocation. Bone spurs can also contribute by rubbing against the tendon over time. Once the tendon fully detaches, it cannot heal on its own, making early evaluation important for proper treatment planning.
How is a complete rotator cuff tear diagnosed?
Diagnosis begins with a detailed medical history and physical examination to assess shoulder strength, range of motion, and pain patterns. Providers often perform specific movement tests to identify weakness or instability associated with a rotator cuff tear. Imaging is used to confirm the diagnosis and determine severity. X-rays help rule out bone-related conditions such as arthritis, while MRI or ultrasound provides detailed images of the tendons, showing the size of the tear, degree of retraction, and muscle condition. This information is essential for guiding treatment decisions.
What treatment options are available for a complete tear?
Treatment depends on the severity of symptoms, functional limitations, and patient goals. Many patients begin with non-surgical care, including activity modification, anti-inflammatory medications, and physical therapy to maintain motion and strengthen surrounding muscles.
If pain, weakness, or loss of function persists, surgical repair may be recommended. Minimally invasive arthroscopic techniques are commonly used to reattach the tendon to the bone. In some cases, injections may be used to reduce inflammation and improve comfort during non-surgical treatment. A specialist will help determine the most appropriate approach based on the individual condition.
What is recovery like after rotator cuff repair surgery?
Recovery after rotator cuff repair occurs in stages and requires a structured rehabilitation plan. Immediately after surgery, the arm is placed in a sling to protect the repair, and patients may experience swelling and discomfort that is managed with medication and ice.
Physical therapy typically begins with passive motion exercises, followed by gradual progression to active movement and strengthening. Most patients regain functional use of the shoulder within a few months, but full recovery of strength and mobility can take four to six months or longer. Following post-operative instructions and attending therapy are key to achieving the best outcome.
