What a rotator cuff tear is
The rotator cuff is a group of four tendons that centers the ball of the shoulder in its socket and powers rotation and elevation. Tears occur either from a discrete injury — a fall, a lifting event, a dislocation — or from gradual degeneration of the tendon where it attaches to bone.
The size and location of the tear matter more than the word 'tear' itself; a small degenerative tear and a large acute retracted tear are different problems with different treatment paths.
Common symptoms
Rotator cuff symptoms tend to build over weeks to months when the tear is degenerative, and appear suddenly when the tendon is torn during an injury.
- Pain over the outside of the shoulder and upper arm
- Night pain that interrupts sleep, particularly lying on that side
- Weakness lifting the arm overhead, reaching out or reaching behind the back
- Loss of strength with rotation, such as opening a door or reaching a seatbelt
- Catching, clicking or a sensation that the shoulder is not working properly
Common causes
Degenerative tearing is the most common pattern, developing where the tendon attaches to bone and becoming more frequent with age. Traumatic tears occur with a fall onto the arm, a heavy lift, or after a shoulder dislocation.
Repetitive overhead work and overhead sport increase the load on the cuff, and smoking and diabetes are associated with poorer tendon quality and healing.
When to see an orthopedic surgeon
Prompt evaluation is worthwhile when weakness follows an injury, when the arm cannot be raised, or when pain persists beyond several weeks of rest and activity modification. Tears that are left to retract and the muscle that becomes fatty over time can become unrepairable, so acute injuries in active patients are best seen early.
How the diagnosis is made
Evaluation starts with the history and a physical examination that tests each part of the cuff individually, along with the biceps tendon and the shoulder joint itself. X-rays are obtained to assess the bone, joint space and any arthritic change. MRI is used when the examination suggests a structural tear or when non-operative care has not worked, because it defines tear size, tendon retraction and muscle quality — the factors that determine whether repair is likely to hold.
Non-surgical treatment options
Many patients are treated without surgery. A rotator cuff program focuses on restoring motion, then rebuilding the strength of the remaining cuff and the scapular stabilizers so the shoulder can function despite the tear. Activity modification, anti-inflammatory measures and a corticosteroid injection can each play a role.
This path is reassessed on a defined timeline rather than continued indefinitely. If pain and weakness persist, or if the tear pattern is one that tends to enlarge, repair is discussed.
What the repair involves
Arthroscopic repair is performed through several small incisions with a camera inside the joint. The torn tendon is mobilized and brought back to its attachment on the humerus, where it is secured with suture anchors placed in the bone. Associated findings — biceps tendon pathology, labral tearing, bone spurs contributing to impingement, or arthritis at the AC joint — are treated in the same setting when they are contributing to symptoms.
Surgery is usually outpatient, under general anesthesia with a regional block for post-operative pain control.
Recovery and rehabilitation
The biology of tendon healing to bone sets the pace of recovery, and the early phase is deliberately protective. A sling is used for a period of weeks; passive and assisted motion begins early to prevent stiffness, with active motion and then strengthening added in stages.
Recovery is measured in months rather than weeks, and progress is judged by motion, strength and comfort rather than by the calendar alone. Written protocols are provided so you and your therapist are working from the same plan.
- Protected phase: sling use, passive motion, pain control
- Motion phase: active-assisted then active range of motion
- Strengthening phase: cuff and scapular strengthening
- Return phase: work, overhead activity and sport-specific loading
Why patients choose Dr. Horner for rotator cuff care
Dr. Horner is a board-certified orthopedic surgeon with fellowship training in sports medicine and shoulder surgery at Rush University Medical Center, and he has cared for professional athletes in Chicago. Rotator cuff problems are a core part of his practice, and non-operative care is offered as seriously as surgery when it is the better option.
Patients are seen at Oak Brook on Mondays, Little Village on Wednesdays and St. Charles on Thursdays.

Common questions
What does a rotator cuff tear feel like?
Most people describe pain over the outside of the shoulder and upper arm, difficulty sleeping on that side, and weakness reaching overhead or behind the back. A tear from a fall or a lifting injury can also cause sudden weakness rather than pain alone.
Does every rotator cuff tear need surgery?
No. Many partial tears and some smaller full-thickness tears improve with a structured rehabilitation program, activity modification and occasionally an injection. Repair is considered when pain and weakness persist despite that, when a tear is acute and retracting, or when the tear pattern is unlikely to do well over time.
How soon should a rotator cuff tear be repaired?
Acute tears in younger, active patients are generally evaluated promptly, because tendon that retracts and muscle that becomes fatty over time is harder to repair. Degenerative tears are less time-critical and are often treated non-operatively first. Timing is decided at consultation.
Is rotator cuff repair done arthroscopically?
Most repairs are performed arthroscopically through several small incisions, using anchors placed in the bone to bring the tendon back to its footprint. Associated problems such as biceps pathology or impingement are addressed at the same time when present.
How long is the sling worn?
A sling is typically used for several weeks to protect the repair while the tendon begins to heal to bone. The exact duration depends on tear size, tissue quality and the repair performed, and is specified in your protocol.
When can I drive or return to work?
Desk-based work is often possible early, while driving resumes once you are out of the sling and have comfortable, controlled arm use. Overhead and heavy lifting work takes considerably longer and is staged through rehabilitation.
