Abstract

The relationship of patellofemoral congruency with chondromalacia patellae (CP) was retrospectively evaluated. Lateral patellar tilt angle (LPTA), sulcus angle (SA), trochlear depth (TD), and patella angle (PA) were measured at 301 knee magnetic resonance images and compared between groups with and without CP. In the CP group, LPTA and TD were significantly low (P< .01), SA was high (P< .01), while PA showed no difference (P> .05). The parameters were also compared between groups with mild and severe CP, and no significant difference was found (P> .05). Our results demonstrate that patellar tilt and trochlear dysplasia are related to the presence but not the degree of CP. © 2014 Elsevier Inc.
