The lateral ligament (l. lateralis, pna), also known as the lateral ligament or lateral fascia, is a connective tissue structure that connects the medial surface of the thigh to the lateral surface of the leg. It is located on the lateral surface of the thigh and lower leg and plays an important role in maintaining stability of the lower extremities.
The lateral ligament consists of several layers of connective tissue, including collagen fibers, elastic fibers and fibrocytes. It has the shape of a band that runs from the medial surface of the thigh to the lateral surface of the lower leg. Its main function is to support and stabilize the muscles and tendons of the lower extremities, especially in the knee and ankle areas.
In addition, the ligament lateralis plays a role in controlling movement and stability of the lower extremities. It is involved in maintaining balance and controlling the force we use for walking, running and other activities. When the lateral ligament is damaged, it can cause imbalance and cause problems with mobility and stability in the lower extremities.
