Quick Answer
Shoulder arthroscopy is a surgical approach that uses a camera and small instruments through small incisions. It can be used for selected rotator-cuff, labral, biceps and other shoulder disorders. A “shoulder tear” is not one single diagnosis, so not every tear requires arthroscopy.
What Can Be Treated Arthroscopically?
- Selected rotator cuff tears
- Bankart/labral injuries related to instability
- Selected SLAP and biceps-related pathology
- Selected calcific tendinopathy or intra-articular pathology
How Is the Decision Made?
The decision is not based on MRI alone. Age, injury mechanism, tear size/retraction, muscle quality, weakness, pain, activity goals and response to appropriate nonsurgical care all matter. Some cuff tears can be managed with rehabilitation, while selected acute repairable tears may be considered for surgery earlier.
Arthroscopic Repair
The camera is used to assess the pathology and perform the required procedure. A rotator cuff tendon may be reattached to bone with sutures/anchors; labral injury may be repaired or treated differently depending on patient factors. Because many different operations are performed “arthroscopically,” recovery is procedure-specific.
Recovery
Rehabilitation after simple debridement is not the same as rehabilitation after tendon or labral repair. When biological healing must be protected, sling use, controlled motion and strengthening may progress over months. Return to sport is based on function and the operation performed, not time alone.
Frequently Asked Questions
Does keyhole surgery mean very fast recovery?
Not necessarily. Skin incisions are small, but a repaired tendon or labrum still requires biological healing.
Does every MRI tear require arthroscopy?
No. Clinical findings, tear characteristics and patient goals must be considered together.
