I had my surgery on Feb 2022. The doctor had originally felt that he would perform the procedure orthoscopically but early on the procedure, he found the damage to be so severe that an actual incision would be necessary to repair the damage. The surgeon put 9 anchor points in my shoulder which according to him was a LOT of anchors.
At any rate, the first 6-8 weeks were miserable. I could only sleep in a reclining chair, used ice constantly to try and keep the pain down, arm in a sling nearly 24 hours/day - all standard stuff so I have been led to believe. Once I was able to begin physical therapy, things started to improve but only by small amounts. The PT was doing most of the work and I was to be mostly passive. As the weeks went on, I was given more actual exercises to do and my range of motion began to improve pretty dramatically. The pain lessened with each PT visit and the strength in the shoulder/arm began to improve slightly, albeit with very light weights.
I ended up seeing the physical therapist for about 6 months and although my range of motion had become nearly equal to my left (good) shoulder, I didn't have nearly the strength as before my accident and surgery. My ortho surgeon, who I saw every 3 months to gauge progress, told me 6-7 months after surgery that I needed to do everything I could to gain a little more range of motion and any strengthening I could endure. He indicated that 12 months post-surgery, I was unlikely to improve. In other words, I had a target/deadline by which I could improve and after that ... well, I was more-or-less stuck with the progress.
I began playing volleyball and fishing (casting) 8 months post-surgery. I could fish pretty well but volleyball - ugh - I couldn't serve overhand across the net and couldn't begin to swing on the ball in the front row. But the more I played and worked at improving, the better I got. Now, nearly 16 months post-surgery, I'd say that I've probably got 95% range-of-motion and probably 85% of my strength.
Overall, I'm quite pleased with the outcome. As other posters have indicated, strictly adhering to the physical therapy regimen is key.
