Proximal tibiofibular dislocation with multiligament-knee injury: a case report.

Proximal tibiofibular dislocations are extremely rare, accounting for less than 1 % of knee injuries. They can present in isolation as a result of athletic participation or in combination with bony or ligamentous injuries, frequently associated with tibial shaft or proximal tibial fractures caused by high-energy trauma, such as motor vehicle accidents. A cohort study with a sample of 129 knees reports a 9 % incidence of proximal tibiofibular instability in patients with multiligament-knee injurie. Multiligament-knee injuries are also uncommon, primarily resulting from high-energy trauma, posing a challenge for the surgeon, and requires a meticulous clinical evaluation and surgical planning to achieve satisfactory outcomes. This is a retrospective descriptive study based on the collection of clinical data from a patient who was a victim of a motor vehicle accident with proximal tibiofibular dislocation involving the posterior cruciate ligament and posterolateral corner, who underwent a single-stage surgical intervention to ensure early functional rehabilitation. The significance of this case lies in the fact that it represents the second reported case of a proximal tibiofibular dislocation with multiligament-knee injury without other associated injuries, in addition to being a recent case reported ten years after the last similar publication.
