A new fixation method for Hoffa fracture.

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.
