SkierPTOnce you tear the labrum, the biomechanics of the shoulder joint change. The negative “suction” pressure that exists due to the fluid in a closed system is released and no surgery can ever get this back.
For my case I had a moderate lateral labral tear. I had arhroscopic surgery and rehabbed for 6ish months. I didn’t not rehab well enough post-op but I was young and my parents didn’t know any better.
2 years after surgery I dislocated again and re-tore the same labrum. At this point I was getting into fitness and decided surgery wasn’t happening again. I rehabbed myself for months and continue to on and off to this day.
My shoulder is currently stiff lacking external and some internal rotation, BUT it’s mostly stable. I can lift weights as I want, I just avoid overhead press. I can ski and fall hard and be fine. Which makes me think how better it could be if I never had additional trauma via surgery.
I have a similar situation,
I tore my labrum being an idiot skiing in 2014, it kept slipping out of place after trying to rehab it so I got surgery a couple months later. I probably wasn't the most diligent at post-op PT but I did my best and it felt strong.
Two years later I fell on it skiing again, and felt it pop out. That time it subluxed so much less movement and slipped back into place easily. I stopped throwing with my right arm, and hit PT hard, trying to roll my shoulders backward and strengthen my middle back (apparently this contributed to some postural instability). I got it feeling strong, able to rock climb, do pullups and throw again and didn't really think about it much for a while.
Fast forward to last fall. I ate shit washing out on a berm mtn biking, and it subluxed again. Since then I've kinda accepted I just need to consistently do shoulder stabilization and PT and work it into a regular weekly gym routine. OP hopefully you have better luck with the operation, my advice would just be to really put a ton of work into your rehab and PT, even after you feel like its back to normal strength.
