All arthroscopic management of an Hoffa fracture of the medial femoral condyle: case report

Abstract

Introduction: Hoffa fractures are intra-articular fractures of the distal femur in the coronal plane, with an incidence of approximately 0,65 % of all femoral fractures. Isolated fractures of the medial condyle are even less frequently reported.The most frequent mechanism associated is an axial load exerted on a flexed knee. Diagnosis of this fracture might be challenging as standard radiographic studies may appear normal. Due to their intra-articular location, anatomical reduction of this fractures must be achieved and articular congruence restored for the patient to achieve optimal functional results. Case report: The authors present a case of a 38-year-old male patient who sustained a high energy trauma to his right knee. A comminutive Hoffa fracture of the medial femoral condyle was identified. No neurovascular compromise was identified. Arthroscopic reduction of the main fragments was performed followed by fixation with three screws. A posteromedial portal was needed to achieve anatomic reduction. Weight-bearing was allowed at 8 weeks and physical therapy initiated. Six months after the patient had full return to his previous activity level. Conclusion: Anatomical reduction and stable osteosynthesis are required for the management of Hoffa fractures. Arthroscopic management of these lesions is as a successful method, providing good outcomes with few complications associated.
