Arthroscopic Management of a Posterior Femoral Condyle (Hoffa) Fracture: Surgical Technique.

Unicondylar fractures of the lower end of the femur are uncommon injuries that usually occur in the sagittal plane. A coronal (tangential) plane fracture, first described by Hoffa in 1904, is unusual. It is an intrinsically unstable type of intra-articular fracture that warrants operative fixation, usually by an open technique. A simple method for the treatment of lateral femoral condyle coronal fractures with arthroscopic-assisted reduction and internal fixation by cannulated screws is reported. Managing fractures of the posterior femoral condyle with arthroscopic reduction and fixation with cannulated screws is simple and effective and could be reproducible with good results and a good prognosis.
