PCS Physical component summary, MCS Mental component summary; The total WOMAC scores, WOMAC pain scores, WOMAC stiffness scores, WOMAC function scores, SF-12 PCS scores and SF-12 MCS scores were normalized to a range of 0 to 100 points, with higher scores presenting better function
^a Normal distribution data are presented as the mean ± standard deviation and were analyzed with t test
