Posterior Ligament - Knee - PCL
 

I posted on here previously about damaged posterior ligament in knee (PCL) It's normally the ACL thats injured.

Its really hard to get good info on this. The bottom line is That is has no affect on squats or any other excercises involving bending your knee. It's only a problem if your knee is over extended.

I was babying this thing for three decades and finally ran into a sharp sports medicine Dr. And he told me put all the weight i want on that knee. I have for the last two years, with no problems.
