Isolated medial or lateral epicondyle fractures are rare. They usually form part of a more complex fracture around the femoral component.
These fractures are classified by UCPF as V.3-A.
Isolated epicondyle fractures are usually caused by avulsion injury to collateral ligaments.
Plain X-rays remain the first line of investigation.
CT Scan is useful to assess possible fracture extension to the implant interface.
