[Imaging manifestation and medicolegal significance of bipartite patella].
Bipartite patella is uncommon in clinical medicine. It is formed by two or more ossification centers It is repeatedly misdiagnosed as patellar fracture in clinical practice. which do not fused in adolescence. In order to elevate the recognition of imaging signs of bipartite patella and to avoid the fault in medicolegal expertise testimony, three cases of bipartite patella were analyzed in combination of literature review, and the possible causes, histological changes, imaging signs, and clinical manifestation of bipartite patella were also discussed. The three cases concerned were all adults, two male and one female. They all felt pain after knee joint injury and were diagnosed as patellar fracture in medical institutions. Two cases were appraised on the degree of injury and one was on the degree of disability. According to Saupe's grouping, two cases were group III, and one was group II and III. In the practice of medicolegal expertise testimony, recognizing imaging signs of bipartite patella could provide more rigorous and objective conclusion.
