Superior Tibiofibular Joint

Superior tibiofibular joint (shown in red)

The Superior Tibiofibular Joint is a synovial joint that connects the tibia and fibula bones in the lower leg. It is one of two joints that connect these bones, the other being the inferior tibiofibular joint. The superior tibiofibular joint is located near the knee, while the inferior tibiofibular joint is located near the ankle.

Anatomy

The superior tibiofibular joint is formed by the head of the fibula and the lateral condyle of the tibia. The joint is surrounded by a capsule, which is reinforced by anterior and posterior ligaments. The biceps femoris tendon also provides support to the joint.

Function

The main function of the superior tibiofibular joint is to allow for slight movement of the fibula relative to the tibia. This movement is necessary for the normal function of the leg, particularly during walking and running.

Clinical Significance

Injuries to the superior tibiofibular joint can occur due to trauma, such as a fall or a direct blow to the side of the knee. These injuries can result in pain, swelling, and difficulty moving the leg. Treatment may involve rest, physical therapy, and in some cases, surgery.
