Hoffa fracture (HF) typically involves the posterior femoral condyle in the sagittal plane, with an estimated incidence of 0.65% among femoral fractures. It usually occurs at the lateral femoral condyle in high-energy trauma with axial load force over the distal third of the femur and the knee positioned in more than 90° of flexion. The case reported involved a patient with a complex medial HF and associated knee dislocation after a high-energy trauma. At two years of follow-up radiologic analysis showed a complete bone healing and allograft integration. Transplantation of osteochondral allografts should be considered in cases of complex HF, and it aims at restoring the anatomy of the joint surface to prevent early post-traumatic osteoarthrosis in young patients.
霍法骨折（HF）通常累及股骨髁后部矢状面，在股骨骨折中估计发病率为0.65%。它通常发生于高能创伤时的股骨外侧髁，轴向负荷力作用于股骨远端三分之一，膝关节处于屈曲超过90°的位置。报道的该病例涉及一名高能创伤后发生复杂内侧霍法骨折并伴有膝关节脱位的患者。随访两年时的影像学分析显示骨完全愈合且同种异体骨融合。对于复杂霍法骨折病例应考虑进行骨软骨异体移植，其目的是恢复关节面解剖结构，以防止年轻患者创伤后早期骨关节炎。
