If you’re young and play contact or overhead sport, surgery after a FIRST dislocation is worth a serious conversation.
In trials of young, active people, about 1 in 2 dislocated again without surgery. With surgery, it was about 1 in 16. Put another way, for every two or three young people operated on, one repeat dislocation is prevented. That’s unusually good for any orthopedic operation.
If you’re older, less active, or over 40, the case is much weaker. The research simply wasn’t done in people like you.
What the surgery does
- A keyhole repair reattaches the torn rim of cartilage (the labrum) to the front of the socket with small anchors
- Recovery is long: usually a sling for a few weeks, then months of rehab. Contact sport is often around six months away
- If there’s bone missing from the socket, a different, bigger operation may be needed
Surgery wins for the young athlete. For everyone else, the evidence runs out.
Who it suits best
- Teens and people in their early twenties
- Contact, collision and overhead sport: rugby, football, martial arts, basketball, volleyball, climbing
- Jobs where the shoulder coming out would be dangerous: police, military, firefighters, people working at height
- A shoulder that already feels loose or has come out more than once
The honest caveats
- The trials were small and mostly in young men who play sport
- Real-world results are less dramatic. A large UK study found about 1 in 5 dislocated again within a year whether or not they had surgery. The groups weren’t directly comparable, but it’s a reason not to see surgery as a guarantee
- The non-surgery groups in the trials used old-style rehab, with weeks in a sling and late strengthening. Modern rehab may close some of the gap
- Half of people whose shoulder comes out again choose not to have surgery even then
- Surgery doesn’t prevent arthritis later
- Over 40: there’s no trial of surgery versus rehab for a first dislocation. The bigger issue at that age is usually the rotator cuff. See dislocated shoulder over 40
If you choose not to have surgery
- A short time in a sling, then early movement. See how long to wear a sling
- A proper strengthening program for the rotator cuff and shoulder blade
- Patience before contact sport. Going back early is the biggest risk you control
- Surgery stays on the table if the shoulder comes out again. You haven’t closed the door
Questions to ask your surgeon
- What did the scan show: a torn rim only, or bone loss too?
- What’s my chance of it happening again with and without surgery, at my age and with my sport?
- How long until I can play contact sport after surgery, and without it?
- If I try rehab first and it comes out again, will the operation be harder?
For your odds of it happening again by age, see will a dislocated shoulder pop out again?
Get it checked if
- The shoulder feels loose, slips or “goes dead” with overhead or throwing movements
- It has come out more than once
- You’re over 40 and the arm is still weak after two weeks
- A new season or physically demanding job is coming up and you haven’t decided
Young, active and in contact sport: surgery earns its place. Anyone else: rehab first, and keep surgery in reserve.
