Abstract Purpose To investigate the clinical effect of a new fixation method for Hoffa fractures. Methods We treated eleven patients with Hoffa fracture using the new fixation method (fixation with one screw inserted from the femoral intercondylar notch and two screws inserted from the nonarticular lateral (or medial) surface of the fractured condylar fragment; the two sets of screws were crossed). Results After an average follow-up period of 24 months (range 5–28 months), all fractures had healed. The average healing time was 11.6 weeks (range 9–14 weeks). On the version of the Knee Society Score modified by Dr. John Insall in 1993, the average score was 174.6 points (range 125–199 points). Conclusions The new fixation method for Hoffa fracture is effective, and may provide a new way to treat Hoffa fractures.
Association. Most of them need surgical treatment to achieve a good outcome. Traditional methods of fixation for Hoffa fractures have resulted in either complex constructs, in order to achieve stability, or in large articular surface defects that are created while countersinking lag screws. Both have negative implications for the patient [1]. We have treated eleven patients with Hoffa fracture using a new fixation method. In this novel technique, the fracture is fixed with three screws: one screw is inserted from the femoral intercondylar notch, and the other two screws are inserted from the nonarticular lateral (or medial) surface of the fractured condylar fragment. The two sets of screws are crossed so that both sides of the fracture lines are completely compressed, meaning that the fixation is more stable. This method only damages the articular cartilage in non-weight-bearing regions, thus decreasing the risk of osteoarthritis.

Introduction Hoffa fractures are intraarticular fractures that are classified as type 33-B3 fractures by the Orthopaedic Trauma

From April 2004 to July 2009, we treated eleven fractures in eleven patients using the new fixation method. There were nine males and two females aged from 23 to 48 years (average 37.3 years). Seven fractures were lateral and four were medial. In all patients, the mechanism of injury was a motor vehicle accident. According to the Letenneur classification [2], seven fractures were type I, one was type II, and three were type III. Preoperative X-rays and MR images of one of the eleven cases are shown in Figs. 1 and 2.
