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

Area of Science:

• Orthopedic Surgery
• Traumatology
• Sports Medicine

Background:

• Proximal tibiofibular dislocations are rare, <1% of knee injuries, often linked to high-energy trauma or athletic activities.
• Multiligament knee injuries are uncommon and challenging, requiring precise evaluation and surgical strategies for optimal outcomes.
• Proximal tibiofibular instability occurs in 9% of patients with multiligament knee injuries.

Observation:

• This study presents a rare case of proximal tibiofibular dislocation with posterior cruciate ligament and posterolateral corner involvement.
• The patient sustained these injuries from a motor vehicle accident, without additional fractures or ligamentous damage.
• A single-stage surgical intervention was performed to facilitate early functional rehabilitation.

Findings:

• The case represents the second reported instance of proximal tibiofibular dislocation with multiligament knee injury as an isolated injury pattern.
• This unique presentation occurred ten years after the last similar case was published, highlighting its rarity.
• The surgical approach aimed for early restoration of knee function.

Implications:

• This case underscores the importance of considering proximal tibiofibular dislocation in multiligament knee injuries, even without other associated trauma.
• It emphasizes the need for meticulous clinical assessment and tailored surgical planning in such complex cases.
• Further research into optimal single-stage surgical interventions for these rare injuries may improve patient outcomes and rehabilitation.
