The tibiofibular ligaments stabilise the joint at the top of the fibula where the fibula forms a synovial joint with the tibia.
The proximal tibiofibular joint
This joint is often referred to as the 'neglected' or 'forgotten' joint as doctors do not pay it much heed in their evaluation of pain or instability at the side of the knee. Its main function is to disperse the forces that the ankle experiences with the very mobile actions of the ankle joint. Injury to the joint is generally the consequnce of a severe twisting ankle injury.
