The rotator cuff is a group of four small muscles and their tendons that wrap around the head of the humerus and control fine shoulder motion. Tears in the cuff, most commonly in the supraspinatus tendon, are extremely common, particularly with age. Many rotator cuff tears are asymptomatic and require no treatment.
When a cuff tear is symptomatic, causing weakness, pain, or significant functional limitation, modern arthroscopic repair is reliable and durable. The art of cuff surgery is knowing which tears need repair, which are best managed conservatively, and which are too far gone for repair alone.
Symptoms of a rotator cuff tear
Common symptoms include:
- Pain on the outside of the shoulder, often worse at night
- Weakness with overhead activity, reaching to a shelf, brushing hair
- A sensation of catching or grinding with motion
- Difficulty sleeping on the affected side
- Pain that radiates down the upper arm but not below the elbow
How rotator cuff tears are diagnosed
MRI is the standard imaging study for a suspected rotator cuff tear. The exam, assessing strength of each cuff muscle individually, guides the suspicion before imaging. Ultrasound is sometimes used as a screening tool and can be valuable when MRI is contraindicated.
Plain X-rays are not used to diagnose cuff tears themselves but are taken to rule out arthritis, calcific deposits, or other conditions that may be causing the symptoms.
Not every rotator cuff tear needs surgery. Many are asymptomatic findings on MRI. Even some symptomatic tears respond well to a structured course of physical therapy, anti-inflammatories, and selective injection, particularly partial-thickness tears and small full-thickness tears in older patients.
When surgery is appropriate, Dr. Lee performs all-arthroscopic repair using current-generation suture anchor constructs. The technique restores the tendon to its bony footprint with the strongest available fixation. Aggressive but disciplined rehabilitation gets the shoulder back to function, most patients regain the motion they had within months and the strength within a year.
Non-surgical treatment
Rotator cuff tendon problems occur in a spectrum, from inflammation, to small-mid-high grade partial tears, to full tears. Anything but a full tear can respond well to a structured program of physical therapy focused on scapular mechanics, and posterior cuff strengthening.
Injections such as corticosteroids can be helpful for the inflammatory stage, but actually harmful in the partial tear phase, in which case PRP can be very helpful. A reasonable trial of conservative treatment is typically 6–12 weeks before reassessing.
Arthroscopic rotator cuff repair
When indicated, all-arthroscopic repair is performed through small portals around the shoulder. The torn tendon is mobilized, the bony footprint is prepared, and the tendon is secured back to bone with suture anchors. Single-row, double-row, and transosseous-equivalent constructs are used depending on the tear pattern. Depending on the severity and chronicity of the tear, various other modalities may be utilized to optimize the repair such as patches, balloons. The surgery is typically outpatient with regional anesthesia plus light sedation.
Recovery timeline
Rotator cuff repair is a long rehabilitation. The roadmap:
- Weeks 0–6Sling immobilization. Passive range of motion only, therapist or other arm moves the shoulder. No active use of the cuff. Elbow, wrist, and hand motion encouraged.
- Weeks 6–12Sling discontinued. Begin active range of motion. No resistance. Pain typically declines significantly during this phase.
- Months 3–6Progressive strengthening. Functional return for daily activities and light occupational use.
- Months 6–12Continued strengthening to full. Return to sport, manual work, and overhead activity. Strength continues to improve up to a year after surgery.
What patients commonly misunderstand
Common misunderstandings about cuff tears:
- Not every tear needs to be fixed. MRIs in adults over 60 frequently show cuff tears in shoulders that don't hurt. The decision to operate is based on symptoms and function, not on imaging alone.
- Rehab is the surgery's job, not yours alone. The technical repair is one component. Outcome depends heavily on the post-operative therapy. Skipping or shortcutting the protocol is the most common cause of stiffness or re-tear.
- Massive tears have other options. Some tears are too large or too retracted to repair primarily. Options for these include partial repair, the addition of patches, tendon transfer, or, in the right older patient, reverse shoulder replacement. Dr. Lee can discuss whether your tear is reparable based on your MRI.
