dealing with knee pain is often not simply an issue of dealing with the knee and its surrounding tissues. Making sure you get rid of your knee pain can, and more often will, mean not just work on making sure the knee flexes and extends but that the tibia/femur glide properly over one another that there is no restriction in dorsi and plantar flexion and that the hip flexes and extends fully. So, in other words, a knee pain could be considered not to be just a knee problem but a leg problem.
