My injury was misdiagnoised 17 months ago. I under went PT for a torn hamstring. I continued on my own with the strenghthing excersises etc. When I was no longer seeing any results and the mass in the back of my lege was not going away, I went back. I was told that I have a complet hamstring avulsion from the ischium. (basically my hamstring is completely detached from my butt). I went to see one surgeon who has done the surgery, but did not know what the success rate would be for me because of the time that has passed. I am looking for anyone who has had the surgery, or anyone who can talk about possible success rates. I am very active, and would like to remain that way. Thanks.
