I had ACL reconstructive surgery 9 weeks ago. I have had a really hard time with Flexion...I had to have my quad pushed aside because the initial clamp did not want to take to my bone, so a screw and washer had to be put on. Due to this I had a Charley Horse in my quad for the first three weeks making it nearly impossible to get any bend. So at 9 weeks I am only at 90 degrees. I do my therapy at home, I work my butt off at PT and yet I'm not getting anywhere. I do the heel slides, the quad sets, the bicycle, the hamstring curls, I even have my fiance pushing to get extra degrees. IS there ANYTHING else I can do?? The doctors are saying I may have to go back under and do manipulation... Thank you!
