Hoffa fracture is a general term for single condylar or double condylar coronal fractures of the distal femur. It is a rare intra-articular fracture. At present, there is no specific fixation method for such fractures. The traditional method to fix Hoffa fracture mainly includes cannulated screws, however, failures of this type of internal fixation have been reported from time to time. Therefore, many scholars have proposed a more solid internal fixation that used cannulated screws combined with a buttress plate or lateral plate to treat this type of fracture, which has been widely recognized. Currently, there is no specially designed anatomical plate for lateral fixation of comminuted Hoffa fractures. In this report, we demonstrate a comminuted Hoffa fracture fixed by cannulated screws combined with a calcaneal reticular plate. The patient was followed up for 14 months. The knee joint ROM was 0- 120°, and the KSS score was 90 at the last follow-up. The efficacy was excellent according to the evaluation of Letenneur function. There was no pain after the activity and recovered to the pre-injury movement and exercise ability.
