I am feeling that just above both knees actually. Makes it very uncomfortable to do squats and such at first. I'm using hack squats, smith machine squats (which I have never done before) and leg press to really isolate my lower quads. My upper quads are strong I need to balance the lower quads more. On leg day especially I have to do a really thorough warm up or my quads hurt to bad to squat down. My surgeon told me that it's a reaction to the surgery to some extent in my right leg, couldn't explain why it hurt on my left. Oh well, I figured it was just from sitting on my ass for two years.
