It is suggested that female runners are more prone to develop PFPS compared to male athletes. Biomechanical abnormalities are thought to contribute. Lack of evidence is present, thus, authors conducted this study to investigate whether significant differences during running exist in hip, trunk and foot kinematics between females with and without “runners knee”.
Significantly greater peak hip adduction and hip internal rotation were found in the PFP group. No significant difference was found in peak contra-lateral pelvic drop. There was a non-significant trend towards differences in peak contra-lateral trunk lean with the PFP group having lower values. PFP group demonstrated significantly greater peak shank internal rotation. There was no difference in peak rearfoot eversion, forefoot dorsiflexion, or forefoot abduction between groups.
Authors note that their findings are consistent with previous research where excessive hip adduction and hip internal rotation in runners with PFPS increases the dynamic Q angle and may result in greater compressive stresses on the patellofemoral joint. Nevertheless, cause and effect issue remains. They conclude that the study support the continued development of interventions to improve hip control in female runners with PFPS. Clinicians should benefit from the findings by designing exercise programs focusing on restoring normal hip kinematics in both the frontal and transverse plane.
