If I understand what you are asking about scar tissue here is my situation. Because I had a bicycle accident I injured my shoulder and many months later I was told that if I had the type of surgery you are reffering to where they put you to sleep at the hospital and the orthapedic surgeon breaks up the scar tissue then PT? Mine might have been more successful if my doctor had not gone on vacation right after my surgery because that delayed PT. I did have the chair you sit in and move your shoulder for a week at hours at a time. I eventually went to another well known PT and she said she gets her patients in the day of surgery or otherwise the scar tissue sticks again. I think from what I understand if I had have had PT from the 1st day forward my results would have been very different. I think you should consider it because it will bother you from this day forward if you do not. You need PT the day of surgery until you have the use of your elbow like it used to be. How did you injure it?
