The Patella is the technical term for the knee bone. The muscles of the thigh, front of your upper leg, come together and attach to a large tendon called the Patellar tendon. The Patellar Tendon passes over the Patella bone, which gives your leg muscles leverage for walking and kicking. The movement of the tendon up and down as the thigh muscles contract and relax, is called “Tracking”.
Proper Patellar Tracking has no symptoms. If the Patellar Tendon goes off the normal track, it can cause knee pain or weakness in the thigh muscles such as difficulty walking upstairs or running.
