摘要
Introduction: Hoffa fractures are rare and difficult to treat for orthopaedic surgeons. The mechanism of injury of Hoffa fracture is still unknown and the operation approch and fixation method are still controversial. The aim of this study is to compare the clinical effect between two fixation methods on Hoffa fractures. @@@ Case description: From April 2004 to July 2013, we treated eleven patients (new method group) with Hoffa fracture using the new fixation method (fixed with intercondylar screw and crossed screws) and sixteen patients (traditional method group) using the traditional fixation method (fixed with anteroposteriorly placed screws). All documents from their admission until the last followup in December 2015 were reviewed, data regarding complications collected and results were evaluated using the Knee Society Score. @@@ Discussion and Evaluation: After an average follow-up period of 27.1 months (range 24-32 months), all fractures had healed. The average healing time of the new method group was 11.36 weeks (range 9-14 weeks) and the average healing time of the traditional method group was 11.88 weeks (range 9-14 weeks). According to the Knee Society Score, the average score of the new method group was 176.36 points (range 125-199 points), and the average score of the traditional method group was 171.19 points (range 148-197 points). Statistical analysis (t test, t = 0.76, P > 0.05) showed that the difference of both the healing time (t test, t = 0.94, P > 0.05) and the score between these two groups was not significant. @@@ Conclusions: These results indicate that the new fixation method for Hoffa fracture is as effective as the traditional method and may provide a new way to treat Hoffa fractures.
