Coronal plane “Hoffa” fractures of the distal femoral condyle treatment and outcome

Abstract

Introduction: Coronal plane "Hoffa" fractures of the distal femoral condyles are a rare entity. Lateral fractures are three times more common than medial fracture. They are commonly associated with supracondylar fractures of the distal femur however as an isolated injury they are rare. Results: Union was achieved in all 20 patients. The articular surface was reduced anatomically in all but one patient. There was no loss of reduction or fixation. Functional outcome measures showed a continuous significant improvement in function over the 1-year follow up period. Study period was between Jan 2018-December 2018. Complications include stiffness and pain in one patient, collateral laxity in two patients and progression of arthritis in one patient. Conclusion:Here, we summarized the injury mechanism, diagnosis, classification, and treatment options of Hoffa fractures.
