ARTHROSCOPIC ROTATOR CUFF REPAIR
Restore Strength.
Restore Function.
Rotator cuff repair is performed to reduce pain, restore shoulder strength, and improve long-term function when a torn tendon no longer works properly.

What Is The Rotator Cuff?
The rotator cuff is a group of four muscles and tendons that stabilize the shoulder and allow the arm to lift, rotate, reach, and perform overhead activity.
Why Tears Happen
- Degeneration over time
- Traumatic injury
- Overuse
- Acute lifting injuries
- Progressive tendon wear
Common Symptoms
- Night pain
- Weakness
- Difficulty lifting the arm
- Pain with overhead activity
- Loss of shoulder function
Arthroscopic Rotator Cuff Repair Animation
This animation demonstrates arthroscopic rotator cuff repair using anchors and sutures to restore the torn tendon back to bone.
How The Repair Heals
The repaired tendon must biologically heal back to bone after surgery. The strength of the repair initially comes from sutures and fixation devices, but long-term success depends on tendon healing and rehabilitation.
Factors That Affect Healing
- Tear size
- Tissue quality
- Tendon retraction
- Muscle atrophy
- Smoking status
- Diabetes and metabolic health
Why Protection Matters
- Tendon-to-bone healing takes months
- Early protection reduces stress on the repair
- Motion is restored gradually
- Strengthening begins only when healing allows
- Rehabilitation is individualized
Recovery And Rehabilitation
Recovery after rotator cuff repair focuses on protecting tendon healing while gradually restoring motion, strength, and long-term shoulder performance.
First Phase
Protect the repair while pain and inflammation improve.
Motion Phase
Gradually restore safe shoulder motion under guidance.
Strength Phase
Progressively rebuild strength after tendon healing advances.
Return Phase
Resume work, recreation, and sports based on healing and function.
Does every rotator cuff tear need surgery?
No. Treatment should connect the tear’s features with your pain, weakness, goals, and response to earlier care. Physical therapy and surgery can both improve symptoms in selected small and medium full-thickness tears. A tear can also enlarge during nonoperative care; symptom improvement does not necessarily mean the tendon has healed.
Bring these questions to your appointment:
- Is my tear partial or full thickness, and is it repairable?
- What would a trial of nonsurgical care involve?
- Would waiting change my treatment options?
- What outcome is realistic for my work, golf, tennis, or gym routine?
What longer follow-up tells us
A randomized study following 103 patients with tears no larger than 3 cm found better shoulder outcomes with primary repair at 15 years. Fifteen of 51 patients initially assigned to physiotherapy eventually underwent surgery. This informs long-term decisions, but it does not establish that every tear needs an operation: the study involved a selected population and older surgical techniques.
What repair can—and cannot—promise
Repair reconnects tendon to bone. Persistent symptoms, stiffness, infection, nerve injury, and failure of the tendon to heal are possible. Tear size, tissue quality, and associated procedures affect the recovery plan.
Rehabilitation progresses from protection to motion and then strengthening. Feeling better is not permission to lift: obtain clearance before advancing activity.
