Abstract
Medial femoral condyle malunion in the coronal plane is a very rare injury. In this presented case, we performed intra-articular corrective osteotomy for a malunited medial femoral condyle in the coronal plane of a 22-year-old man and obtained good functional and radiographic results. Corrective osteotomy for a malunited medial Hoffa fracture is technically very challenging, but intra-articular corrective osteotomy for these malunited fractures offers a good outcome and should be considered as a salvage treatment.
Highlights
Coronal plane fractures of the femoral condyles are rare intra-articular injuries [1]
The first known description of a coronal fracture of the lateral femoral condyle was published by Busch in 1869
In Type I and Type III Hoffa fractures, some soft tissue elements remain attached to the fractured condylar fragment to provide blood supply [14]
Summary
Coronal plane fractures of the femoral condyles are rare intra-articular injuries [1]. The mechanism of injury for a coronal plane fracture of the medial femoral condyle has reported that a direct impact on the medial side with the knee at 90° of flexion can cause trauma [3,5,6,7]. Treating these fractures is important to achieve good anatomical reduction of the articular surface. Corrective osteotomy for medial femoral condyle malunion in the coronal plane is an acceptable salvage option, as it can reduce pain, improve the range of motion of the knee, and prevent joint damage and posttraumatic arthritis in the future [4].
