Ligaments - What Are Ligaments - Functions Of Ligaments - What Is A Torn Ligament

In this video I discuss ligaments, what are ligaments and the functions of ligaments. I also discuss ligament tear and what do ligaments do. Notes... What are ligaments? Ligaments are connective tissue that connects bones to other bones. They are made up of collagen fibers, which are packed close together; collagen is a structural protein that is found in connective tissues, bones, skin and blood vessels. Ligaments limit how much a joint can move in a given direction, so, they stabilize the joint. Ligaments also protect joints and bones, as they can absorb shock as the body moves. Ligaments can stretch a little bit, however, if they are lengthened too much, the joint can be weakened creating future issues. Several things can affect ligaments, which in turn can affect a joint’s range of motion or restrict flexibility. Inactivity, and overdeveloped muscles can have negative effects on joints and range of motion, overstretching can damage ligaments and decrease joint stabilization, and ageing can negatively affect ligaments and joints, but regular exercise can delay this process. If we take a look at a knee joint, we can see 4 different ligaments, the acl, pcl, mcl, and lcl (illustration on screen). Ligaments can suffer partial or complete tears as you see in this illustration. Most common ligament damage occurs in athletes, for instance the acl. If it is a partial tear, a surgeon will typically attempt to stitch it, if it is a full tear, it is a much more complicated, and usually a surgeon will replace the ligament with a piece of a healthy tendon.
