I had a lateral shoulder tendon relocation surgery, what that means is my rotator cuff snapped and retracted and had to take tendon from back to replace tendon in rotator cuff. Not many doctors perform this and maybe two a year are done. Considering problems of range and strength not doing it there is significant progress, it’s slow like a year long but your retraining a muscle group. 8 months after Dr Ablove performed that surgery I developed a bone spur that impinged on bicep tendon on other shoulder that caused pain. That surgery was much easier to recover from. His office was great following up, minimal wait times and I was fortunate to not have surgery scheduling it a timely manner.
