My shoulder dislocated once. Will it happen again?

It depends mostly on age and activity. Young, active patients have a high chance of recurrent dislocation after a first episode, while older patients are less likely to re-dislocate but more likely to have a rotator cuff tear. Imaging and an exam define your specific risk and guide whether rehabilitation alone is enough.

Do I need surgery after a dislocation?

It depends. Many first-time dislocations, especially in older patients, do well with rehabilitation. Surgery is considered for recurrent instability and for young athletes at high risk of it happening again. Arthroscopic repair reattaches the torn labrum to restore stability.

What does the surgery involve?

Most stabilizations are done arthroscopically, reattaching the torn labrum to the rim of the socket with suture anchors through small incisions. If repeated dislocations have worn away bone, a bone-augmentation procedure may be added. Recovery protects the repair early, then progresses to strengthening and return to sport.

Shoulder Dislocation & Instability, Steven J. Lee, MD

A shoulder dislocation happens when the ball of the upper arm comes out of the socket, most often forward (anterior) after a fall or a forceful overhead movement. The first dislocation usually tears the labrum, the rim of cartilage that deepens the socket, which is what can leave the shoulder unstable afterward.

Age and activity strongly influence what happens next. Younger athletes have a high rate of recurrent instability after a first dislocation, while older patients are more likely to have an associated rotator cuff tear. The pattern guides whether rehabilitation alone is enough or whether surgery is warranted.

First-time versus recurrent

A first-time dislocation is reduced (put back in place) and rehabilitated. In young, active patients the chance of it happening again is high, and recurrent instability, where the shoulder dislocates or feels like it will with certain positions, is what tips toward surgical repair.

Symptoms

Common findings include:

A shoulder that has come out of joint, or repeatedly feels like it will
Apprehension with the arm raised and rotated outward
A sense of looseness, slipping, or 'dead arm' in athletes
Pain and weakness after an episode

Dr. Lee's approach

After a first dislocation, Dr. Lee reduces and rehabilitates the shoulder and uses imaging to define the labral and bone injury. Many patients, especially older or lower-demand ones, do well with rehabilitation.

When instability recurs, or in a young athlete at high risk of recurrence, arthroscopic repair reattaches the torn labrum to the socket rim with suture anchors, restoring stability. When there is significant bone loss, a bone-augmenting procedure may be needed. The plan is matched to the pattern of injury and the demands of the patient.

Non-surgical treatment

A first-time dislocation is reduced and treated with a brief period of rest followed by a structured rehabilitation program focused on the rotator cuff and shoulder-blade muscles. Many patients, particularly older ones, regain a stable, functional shoulder this way.

Surgical treatment

For recurrent instability, the torn labrum is reattached to the socket arthroscopically with current-generation suture anchors. When there is meaningful bone loss from repeated dislocations, a bone-augmentation procedure restores the socket. The goal is a stable shoulder that returns to activity.

Dr. Lee helped design many of the suture-anchor systems used in orthopedics, which gives him deep familiarity with anchor-based labral repair.

Recovery timeline

Recovery after stabilization protects the repair while restoring motion:

Weeks 0 to 4
Sling to protect the repair for 4-6 weeks. Begin gentle, guided motion within safe limits with the guidance of a physical therapist.
Weeks 4 to 12
Progressive range of motion and rotator-cuff strengthening in therapy.
Months 3 to 6
Sport-specific strengthening and a graded return to contact and overhead activity.

What patients commonly misunderstand

What surprises most patients:

Age changes the risk. A young athlete who dislocates has a high chance of it happening again, while an older patient is more likely to have a rotator cuff tear. The right workup differs by age.
Repeated dislocations cause damage. Each dislocation can wear away bone and cartilage. Recurrent instability is worth addressing before that bone loss makes the repair more complex.

Shoulder that has come out, or feels loose? The right plan depends on the pattern.

Shoulder instability is common after a dislocation, especially in younger athletes. Many shoulders settle with rehabilitation, while recurrent instability is reliably treated with arthroscopic repair. An accurate assessment of the labrum and any bone loss directs the plan.
