I have a 4th degree ac separation from a snowboarding accident 5 years ago. would there be any point in getting surgery now?

Possibly: If you are having significant pain, instability or problem doing your normal activities or sports you may need to have something done to help improve your situation but i wouldnt have it done only for cosmetic reasons.

AC joint: No point in surgery unless you are having painful symptoms.

AC SEPARATION: Typically an AC JOINT separation can be treated conservatively when it is only a type 2 or 3. Treatment consists of therapy to regain motion after a short period in a sling. If pain persists or you have pain with activities then sometimes surgical intervention is warranted. Surgery even after 5 yrs would be beneficial. Hope this information is helpful. Take care.
