Introduction: Hoffa is a coronal fracture of the femoral condyle. It is an uncommon injury easily missed on X-rays, which later presents as a non-union. Computed tomography (CT) scan knee helps in diagnosing undisplaced fractures and planning the management.
Case Report: A 24-year-old male patient presented to us with complaints of pain, decreased range of knee movements, difficulty in walking and clicking sound at the left knee for 9 years. The patient had a history of trauma 9 years back. X-ray of the left knee showed the non-union of left lateral Hoffa fracture, which was managed with open reduction and internal fixation with CC screws using the lateral para patellar approach. At present 1.5 years follow-up, the patient is comfortable with no pain and having a complete knee range of motion.
Conclusion: Although Hoffa fracture is rare, clinical suspicion, along with radiological investigations, is essential to diagnose Hoffa fracture. A missed diagnosis can lead to malunion or non-union, which predisposes to knee arthritis. Timely and proper management of Hoffa non-union with open reduction, stable internal fixation and early knee mobilization help in getting a better outcome.
