The knee joins the thigh bone (femur) to the shin bone (tibia). 3) Anterior cruciate ligament (ACL) – lies in the middle of the knee. Ligaments, muscles, and joint proprioception together support exercisers during locomotion. Author to whom correspondence should be addressed. The knee is reinforced by two collateral ligaments, one on the medial side and another on the lateral side, as well as two stronger ligaments (the cruciate ligaments) that prevent excessive anterior, posterior, varus, and valgus displacement of the tibia in relation to the femur. Kiapour, A.M.; Wordeman, S.C.; Paterno, M.V. The implementation of such knowledge should be a priority when dealing with any knee injury/problem. 5. They are distributed around high-motion areas to ensure smooth, friction-free movement. Falls associated with knee instability in people with knee osteoarthritis: Biomechanical risk factors and pain. The posterior aspect of the knee consists of the biceps femoris (biarticular), semimembranosus (monoarticular), and semitendinosus (monoarticular), which form the hamstring group of muscles which function as knee flexors.

All of these receptors project to spinal motor neurons, spinal interneurons, and several supraspinal structures. [, Two fibrocartilaginous menisci, medial and lateral, are positioned between the medial and lateral femoral condyles and the tibia, which accommodate changes in the shape of the articular surfaces during activity. Although their primary function is to produce motion for all the 6 degrees of freedom of the knee, they also interact with the neuromuscular system to control knee motion, and hence play a vital role in knee proprioception. The soleus muscle also resists anterior translation of the knee.

The patellar ligament attaches proximally to the apex of the patella and distally to the tibial tuberosity, and is the inferior continuation of the quadriceps femoris tendon. Arms, S.W. It consists of two bony articulations; the articulation between the femur and tibia bears most of the body weight, while the articulation between the patella and femur creates a frictionless transfer over the knee of the forces generated by contraction of the quadriceps femoris muscle [.
