Forensic analysis of 201 cases of knee injury in traffic accidents

Objective To discuss the characteristics of knee injury in traffic accidents so as to provide an objective basis for its forensic identification. Methods Retrospective analysis was carried out on 201 cases of knee injury in traffic accidents identified by our department from 2006 to 2009. Results According to the types of knee injury,all cases were divided into bone injury group,soft tissue injury group and bone combined soft tissue injury group.Analysis of the knee joint function in the three groups revealed that there were significant differences between bone injury or bone combined soft tissues injury groups and soft tissue injury group in weight bearing including the normal bearing rate and nonbearing rate( P ＜ 0.05,respectively). Conclusions If patients' weight loading,walking functions as well as their gait conditions are introduced into the process of forensic identification for the knee injury in traffic accidents,the identification results will be more reasonable.
