which was over 20 years ago now, 9-12 months was the average, so id be interested in the improvements in treatment they've made to bring that time down to 6 months.
The knee has also always felt different. I originally injured my ACL playing the first game of the season just trying to get warmed up before the Scottish Claymores (NFL Europe) try outs. Never quite got the sprinting burst back or the complete strength of the other knee.
Friends a few years older had the hamstring graft fix, I had the middle of the Patella one.
Either way its a sore, a bore for rehab and later in life!!!!!
