I had full reconstuctive knee surgery 18 years ago. This was well before all this new technology they have today. Back then it was about 6 weeks before I was able to have full motion of my knee. Still longer with rehab. It was about a year before I was confident enough to be active again. Now almost twenty years later my knee is great.
Girl in my gym blew her knee up bad ,, a soccer player .. She had a piece of cadaver put in there .. After a year she's great . don't limp .. does a boot camp training program now .. amazing .. just look at Brady and Welker .. hope all goes well ..
