About a month and a half ago, during off-season agility drills for football I severely injured my PLC. At the end of the drill we had to run and touch the basketball net. When I jumped to hit the net (I have done this drill many times before) I came down and my knee blew out. I tore my PCL, LCL, and PLC and had them all repaired. What I am trying to ask is, I see a lot of talk about PLC deficiency. Is it possible to tear the PLC and not be deficient? And if not does that mean that my other knee has a PLC deficiency?
