Dislocation of the proximal tibiofibular joint typically occurs when an individual endures an impact or falls onto the knee where the knee is in a completely bent position. To learn to recognize and manage bone, muscle and joint injuries including a proximal tibiofibular joint dislocation, register for a first aid course with Toronto first aid today.


The symptoms of proximal tibiofibular joint dislocation typically include swelling and pain on the exterior surface of the shin. It is important to note that the head of the fibula can become more protuberant right below the exterior surface of the knee. When the ankle is moved, the pain in the knee increases and the individual could not bear weight.

Close look on the proximal tibiofibular joint

The tibiofibular joint is considered as an immobile structure that is responsible for connecting the two shin bones. They are separated into two regions such as the upper joint right below the knee and the distal joint which is positioned above the ankle joint. Their function is to reduce movement between the two shin bones that can be caused by twisting movements of the leg. Take note that it is comprised of strong ligamentous bands that traverse in a diagonal manner in between the tibia and fibula bones.

Dislocation of the proximal tibiofibular joint tends to occur quite often when the individual endures a forceful impact or falls when the knee is in a completely flexed position with the foot pointed downwards and inwards. This will place added strain on the muscles which connect the fibula to the foot and toes. During this position, the fibula is pulled out in a forward manner and if there is enough force, it might lead to the dislocation of the joint.

Remember that this injury must be treated as soon as possible since it is often linked with injury to the peroneal nerve. A tibiofibular joint dislocation is different from a whole knee dislocation in which the thigh bone and tibia are separated.

How a tibiofibular joint dislocation is managed

The individual is encouraged to rest and you can apply cold therapy as soon as possible. It is important to avoid aggravating movements particularly inversion of the ankle and full flexion of the knee. Consulting a sports injury specialist must be done immediately.

A sports injury professional can properly diagnose the injury and start the appropriate pain relief measures such as prescribing NSAIDs. The dislocations that are caused by trauma are typically managed surgically where the objective is to fix the two bones back together. This involves the use of a K-wire or screws to keep the two bones in proper place.

Right after surgery, the leg is usually immobilized under a cast for up to 6 weeks. Once the cast is removed, a rehabilitation program is started in order to hasten full recovery.
