Clinical Research Of Lower Extremity Biomechanical Rotation And Patellofemoral Pain About Women

ObjectiveThe purpose of this investigation was to discuss the relationshipbetween the rotation of lower extremity biomechanics and patellofemoralpain(PFP),and to provide theoretical basis for diagnosis.MethodsWith22normal volunteers as controls,21patients with PFP werescaned by ultrathin CT,keeping the bilateral lower extremity straightneutral.The anatomy parameters were measured and analysed, such asfemoral neck anteversion(FNA),femoral neck shaft angle(NSA),posteriorcondylar angle(PCA),femoral rotation relative totibia(FRRT),tibial torsion angle(TTA) and patella tilt angle(PTA).ResultsCompared with control group, the PFP groupFNA、 FRRT、PCA、TTA and PTA increase statistically significant (P <0.05), while the NSA is no statistical difference (P>0.05). By multiple linearregression analysis,it could be found that PTA had the most obvious influence on the VAS score, followed by FNA and TTA; and PTA had themost obvious influence on the WOMAC function score, followed by TTA.Use the Pearson correlation analysis, significant negative correlation couldbe found between PTA and age (r=0.548, p <0.05).ConclusionsPTA is a sensitive indicator to assess VAS score and WOMAC functionscore for individuals with PFPS. Increase s of PTA、F NA、P CA、FRRTand TTA are associated with PFP for women.
