Document Summary
March 5 ch 16: the knee and related structures: complex joint that endures great amounts of trauma due to extreme amounts of stress that are regularly applied. Most sports place a stress on the knee: the knee is a hinge joint with a rotational component. There is very little rotation in the tibia: stability is due primarily to ligaments, joint capsule and muscles surrounding the joint. The 4 main ligaments are the lcl, acl, pcl and mcl. Together these create the main articulation of the knee joint: the fibula plays a small role. It articulates with the tibia and is held in place by a bunch of ligaments: the patella sits on the patellar groove and is a syndesmosis bone and located in the tendons. It functions as protection and creates a fulcrum (pivot point) for the quadriceps: the pcl and acl originate off the distal posterior aspect of the femur.
