Abstract：BACKGROUND:The risk factors for patellofemoral pain syndrome are still unclear and research on risk factors is gradually becoming a hot topic in order to improve the therapeutic outcome of this disease.
OBJECTIVE:To investigate the relationship between lower limb alignment and patellofemoral pain syndrome in young male runners.
METHODS:In the same running population,21 patients with bilateral knee pain,29 patients with single knee pain and 20 normal runners were collected from January 2021 to July 2022.Full-length X-ray examination of both lower limbs in standing position was performed in all subjects.The lateral distal femoral angle,medial tibial proximal angle,joint line congruence angle,hip-knee-ankle angle,and knee physical valgus angle were measured and statistically analyzed.
RESULTS AND CONCLUSION:There was no significant difference in the parameters between the left and right knees in each group(P>0.05).Compared with the normal group,no significant changes in lateral distal femoral angle,medial tibial proximal angle,joint line congruence angle,and hip-knee-ankle angle were observed in the single knee pain group and double knee pain group,while the knee physical valgus angle was significantly increased in these two groups(P<0.05).To conclude,increased knee physical valgus angle may be a risk factor for patellofemoral pain syndrome.
