“Runner’s knee” is another name for patellofemoral pain syndrome, which translates in plain language to kneecap pain. The kneecap is a sesamoid bone located within the tendon that connects the quadriceps muscle to the lower leg bone, or tibia. It functions to improve the forces through the tendon as it crosses the joint and to protect the tendon from wear and tear.
The Patellofemoral Syndrome Solution is a program designed to specifically address this condition. Here is the link: http://patellofemoralsyndromesolution.com/patellofemoral-syndrome-solution/
