    【Abstract】 Objective To measure19parameters of the patellar axial radiograph of college student in order to study the relationship between the chondro-malacia patella and instability of patella.Methods The patellar axial raˉdiograph was taken from49male subject(54joints)and33female subject(37joint)with chondro-malacia patella.All of the subjects were selected in random.The data were analyzed with SPSS For Window10.0statistical software.Results There were significant difference in the patellar index、patellar transverse diameter、lateral patellofemoral anˉgle、index of femoral fossa、the femoral facet ration、the two center angle.Conclusion The patella is more instabler in female patients than in male patients. ......
