Injuries, tendons and menisci
Rotator cuff tears: when is surgery needed, and when can exercise help?
Treatment decisions consider both the tendon tear and how well the shoulder works.
At a glance
- Choose treatment by considering tear size on imaging together with strength and difficulty in daily life.
- If you suddenly cannot lift the arm after an injury, have the injury assessed before starting exercises.
- Exercise therapy and rehabilitation after surgery both play important roles in restoring shoulder function.
For a rotator cuff tear, treatment starts with understanding how it happened and assessing the strength needed to lift the arm. Exercise therapy may improve pain and function in a longstanding tear, but sudden weakness after an injury needs prompt assessment.
How treatment for a rotator cuff tear is chosen
- 01
How it started
Establish whether weakness followed an injury suddenly or pain developed gradually.
- 02
Pain and function
Review movement, strength, sleep, and imaging findings together.
- 03
Choose treatment
Discuss the goals of exercise therapy or surgery and the rehabilitation needed.
- 04
Return to daily life
Increase activities according to recovery of movement and strength as well as pain.
The sequence of assessing an acute injury and considering exercise therapy or surgery for a chronic rotator cuff tear
Assess the tear size and shoulder function together
The rotator cuff is a group of muscles and tendons around the shoulder that lifts and rotates the arm while keeping the joint stable. A tendon may tear suddenly during a fall, or a tear may develop as the tendon weakens over time. You may feel pain when lifting the arm, find it difficult to lie on the affected side, or notice reduced strength when combing your hair or placing something on a high shelf.
Ultrasound or MRI can show which tendon is torn, the extent of the tear, and the condition of the surrounding muscles. Some people have a tear on imaging but little pain and good daily function; others have substantial difficulty despite a small tear. This is why the decision about surgery considers strength, movement, sleep, work, and sporting demands alongside tear size. A tear can enlarge during nonsurgical treatment, so a decline in strength or function should be reassessed.
Seek assessment first if you suddenly cannot lift the arm after an injury
If a fall or a forceful pull on the arm leaves you unable to lift it or causes marked weakness, seek prompt assessment. A fracture or dislocation may be present as well as a tendon tear. Rather than following exercises intended for longstanding shoulder pain, first establish the extent of the injury and the appropriate timing of treatment. Avoid lifting heavy objects through pain.
For a chronic tear that developed gradually without a clear injury, nonsurgical treatment to reduce pain and restore the muscles supporting the shoulder may be an appropriate starting point. A sudden injury and a longstanding tear can require different treatment plans, even though both are called rotator cuff tears. Describe when the pain started, how the injury happened, and which movements you could do before. These details help guide the decision.
Exercise therapy focuses on shoulder function
Exercise therapy helps the remaining tendons and muscles around the shoulder work more effectively. Maintain movement within the limits of pain and gradually add strengthening exercises under the guidance of your clinician or rehabilitation professional. The goal is to use the arm more comfortably in daily life and regain the strength you need, rather than expecting the torn tendon to reconnect spontaneously to its original state.
You do not need to begin with heavy dumbbells or repeated overhead movements of the painful arm. Easier movements with the arm supported or while lying down can be a starting point, with progression tailored to your condition. Reduce the intensity if pain after exercise or at night increases. Medication or injections may help control pain so you can keep exercising, but an injection does not repair the tear itself.
Surgery considers both the tear and your daily demands
Discuss surgery if pain and weakness persist despite nonsurgical treatment, if the tear followed a recent injury, or if your work or sport requires substantial shoulder strength. The size and condition of the tendon, changes in the muscles, and your general health also matter. Surgery reconnects the tendon to the bone, but the same technique is not suitable for every tear.
After surgery, rehabilitation restores movement and strength while allowing the repaired tendon time to heal. When you can raise the arm or lift weight depends on the tear size and the condition of the repair. Rehabilitation may take several months and, in some cases, continue for up to a year. Pain improving first does not mean the tendon has fully healed, so return to daily activities and sport should follow the recovery stage. Tell your clinician which activities you most want to resume. Light housework and overhead work with heavy objects require different levels of shoulder function. When setting treatment goals, review what you can and cannot currently do and how often pain wakes you at night. After treatment, assess whether using the arm has become easier as well as whether pain has decreased.
Common Questions
Does every torn tendon need surgery?
Not every tear requires surgery. Nonsurgical treatment may improve pain and function in chronic tears. The decision considers whether there was an injury, the degree of weakness, the condition of the tear, and your daily demands.
Will exercise make the torn tendon reconnect?
The main aim of exercise therapy is to improve pain and function by making better use of the remaining tendons and surrounding muscles. Improvement in daily function and disappearance of a tear on imaging are different outcomes.
Can I use my arm immediately after surgery?
The repaired tendon needs time to be protected. The timing of movement and strengthening exercises depends on the surgical findings and recovery. Heavy lifting and sport are resumed in stages.

01When to seek medical care
Each warning sign is a separate reason to seek care. Follow the action below if any one applies.
Emergency department · call 119 in Korea
- Call 119 for sudden breathlessness or chest pain, severe faintness or loss of consciousness. Do not wait for calf swelling to appear.
- Go to an emergency department if you suddenly cannot bear any weight, or if an injured knee swells rapidly or looks deformed. A cold or numb foot after injury also needs immediate assessment.
- Seek emergency care for a hot, swollen and severely painful joint with high fever, shaking chills, confusion or inability to bear weight.
- With back or leg pain, go immediately to an emergency department for new difficulty passing urine, loss of bladder or bowel control, or numbness around the genitals or anus. Severe or rapidly worsening weakness or numbness in both legs also needs immediate assessment.
Same-day assessment
- Arrange assessment today for a newly hot, swollen joint, sudden severe pain, or a knee locked so that it cannot fully straighten. Joint infection can occur without fever.
- Have new swelling or pain in one calf assessed today for a possible blood clot. Call 119 immediately if breathlessness or chest pain develops.
- Severe knee pain or a new limp in a growing adolescent may come from a hip condition such as slipped capital femoral epiphysis. Stop walking and sport and arrange assessment today. Go directly to emergency care if they cannot bear weight.
- Stop running and seek assessment today for new recurring groin pain, pain with walking or at night, or a limp. A femoral neck stress fracture needs to be considered. Keep weight off the painful leg until assessed. Go to emergency care if you cannot bear weight.
Book an outpatient appointment
- If none of the warning signs above is present, book an appointment for pain lasting a few weeks, repeated swelling or reduced daily activity and exercise.
