Bilateral Subluxation of the Proximal Tibiofibular Joint: A Rare Case Report.

Introduction: Proximal tibiofibular joint (PTFJ) subluxations are rare and can occur following trauma or sporting events. Idiopathic PTFJ subluxations are more common in females and in patients with generalized ligament laxity. The proper history and clinical examination together with imaging can help in establishing the diagnosis in the majority of cases.

Case Report: We report a rare case of bilateral subluxation of PTFJ and describe the detailed clinical features and magnetic resonance imaging findings. The patient was managed conservatively with good results.

Conclusion: Bilateral subluxation of the PTFJ is a rare clinical entity often associated with specific demographic and physical characteristics, such as young females engaged in high-impact sports. This case underscores the importance of a thorough clinical and imaging evaluation to differentiate it from other causes of lateral knee pain and prominence. Conservative management, including physical therapy and routine follow-ups, has proven effective in managing symptoms and avoiding progression, highlighting the non-operative approach in treating this condition.
