Where exactly are the MCL, ACL, and PCL? About eight years ago I had my right leg lengthened two inches. Ever since then my right knee has been really weak. Especially the ligament on the inside of my knee. Sometimes that whole side of my knee seems to get out of whack, but I can usually fix it by pounding on it with my fist.
In you're right knee, the MCL is located on the left side of your knee (towards your crotch), the ACL is essentially in the middle of the knee (towards the front more), and the PCL is located a little to the left of your ACL (towards the back more). Your LCL is located on the right side of your knee.
