Dislocation of the proximal tibiofibular joint.

Area of Science:

• Orthopedic surgery
• Sports medicine
• Traumatology

Background:

• Dislocation of the proximal tibiofibular joint is a rare injury, often occurring during sports with twisting knee movements.
• The proximal tibiofibular joint plays a crucial role in load distribution and torsional stability of the lower leg.
• Limited case series exist, highlighting the need for more data on treatment and outcomes.

Observation:

• A 23-year-old male soccer player sustained an anterolateral dislocation (Ogden type II) after a sudden change of direction without warming up.
• Physical examination revealed pain and swelling at the fibular head, with no ankle or peroneal nerve involvement.
• Initial manual reduction under anesthesia failed.

Findings:

• Open reduction and internal fixation with screw transfixation of the proximal tibiofibular joint were performed.
• Following screw removal at six weeks, full weight-bearing and physical therapy were initiated.
• The patient returned to soccer activities within four months post-injury.

Implications:

• Proximal tibiofibular joint dislocation should be considered in the differential diagnosis of chronic lateral knee pain.
• Accurate diagnosis relies on technically correct X-rays, comparing the injured knee with the contralateral side.
• Surgical fixation provides favorable outcomes, enabling a rapid return to athletic pursuits.
