1st time was in 1994, I tore them in my left knee, now I am 33 and tore them in my right knee
. I had one month of PT prior to my surgery
where I got my range of motion back and strengthened leg muscles. I selected the cadaver ligament over the other two options, esp since in 94 I had my patella tendon used and it has never been the same since. Numb, freaks me out to shave, NO ONE can go near it, hurts badly if i ever hit it on anything. Again.. this is 15 years later.
