How does the proximal tibiofibular joint become dislocated?
Dislocation of the proximal tibiofibular joint occurs most commonly when the athlete sustains an impact or falls with their knee in a fully flexed position, with their foot pointing inwards (inversion) and downwards. This puts added strain on the muscles which connect the fibula to the foot and toes such as the peroneal muscles. In this position the fibula is pulled forwards and if the force is sufficient it may cause the joint to become dislocated. This injury should be treated quite seriously as it may sometimes be associated with injury to the peroneal nerve.
