Collateral knee ligament, lateral: The knee joint is surrounded by a joint capsule with ligaments strapping the inside and outside of the joint (collateral ligaments) as well as crossing within the joint (cruciate ligaments). These ligaments provide stability and strength to the knee joint.
The lateral collateral ligament of the knee is on the outside of the joint, as indicated here:
The meniscus is a c-shaped cartilage pad between the two joints formed by the femur and tibia. The meniscus acts as a smooth surface for the joint to move on. The knee joint is surrounded by fluid-filled sacs called bursae, which serve as gliding surfaces that reduce friction of the tendons. Below the kneecap, there is a large tendon (patellar tendon) which attaches to the front of the tibia bone. There are large blood vessels passing through the area behind the knee (referred to as the popliteal space).
The large muscles of the thigh move the knee. In the front of the thigh the quadriceps muscles extend the knee joint. In the back of the thigh, the hamstring muscles flex the knee. The knee also rotates slightly under guidance of specific muscles of the thigh.
The knee functions to allow movement of the leg and is critical to normal walking. The knee flexes (bends) normally to a maximum of 135 degrees and extends (straightens) to 0 degrees. The bursae, or fluid-filled sacs, serve as gliding surfaces for the tendons to reduce the force of friction as these tendons move. The knee is a weight-bearing joint. Each meniscus serves to evenly load the surface during weight- bearing and also adds in disbursing joint fluid for joint lubrication.
Lateral collateral ligament (LCL) injuries occur from a varus force to the knee (ie, a force directed at the medial side of the knee or leg).
Ligaments are like strong ropes that help to connect bones together and provide stability to joints. In the knee there are two collateral ligaments. The collateral ...
A few days ago I fell awkwardly and my knee kinda twisted. Then I heard a really loud 'pop' and quite a bit of pain followed on the outer side of my knee.
Lateral ligament sprain on the outside of the knee - cause, symptoms and treatments
This pushes the knee inwards (toward the other knee). Blows to the inside of the knee that push the knee outwards may injure the lateral collateral ligament.
