Abstract:
Objective To improve the recognition and reduce the misdiagnosis of bipartite patella by analyzing and summarizing the imaging features.Methods X-ray,CT and MR images of 1 7 cases of bipartite patella were collected,imaging features were ana-lyzed and summarized.Results X-ray revealed the smooth interface of the main and accessory patella fragments with sclerotic mar-gins,the cleft was slightly wide but not sharp.CT showed the bone sclerosis of interface was mostly smooth,rough and vesicular interface could also be found in a few patients,low density soft tissue could be found in separation zone.MRI could detect the intact but thinned cartilage covering the main and accessory patella fragments,fibrous like tissues could be found in separation zone with MRI.Conclusion Imaging findings of bipartite patella are characteristic,these features are helpful in the diagnosis and differential di-agnosis of bipartite patella.
