In this use, a ligament is a short band of tough fibrous connective tissue composed mainly of long, stringy collagen fibres. Ligaments are also kind of the connective tissue, designed to connect bones, these are tougher and more elastic. The knee flexes (bends) normally to a maximum of 135 degrees and extends (straightens) to 0 degrees. Thus, ligaments and tendons are another example of the structure-function concept and the mechanically mediated adaptation concept that permeate this biomechanics course. Ligaments are vulnerable to injury from stretching, which can cause them to tear. 3. cordlike remnants of fetal tubular structures that are nonfunctional after birth. It is flat, and triangular in form; narrower in the middle than at the ends. Ligaments keep the structure stable; however, it extends from a bone to bone, at a joint and allows the simple and complex motions of the body. The function of a ligament is to provide a passive limit to amount of movement between your bones. Some ligaments limit the mobility of articulations, or prevent certain movements altogether.

During movement of the knee, the anterior cruciate ligament (ACL) prevents anterior sliding of the tibia; the posterior cruciate ligament prevents posterior sliding of the tibia. The LCL stabilizes the lateral side of the knee joint, mainly in varus stress and posterolateral rotation of the tibia relative to the femur. Proprioception . Herniated disc can be caused by twisting or wear and tear over years. Ligaments are bands of tough elastic tissue around your joints. Such a ligament injury is a sprain. The function of tendons is to connect muscle tissues to bones. The main difference between tendon and ligament is that a tendon joins a skeletal muscle to a bone whereas a ligament joins a bone to another bone.
