HSS: hospital for special surgery score; SF-12: 12 short form scale; PCS: Physical Component Summary; MCS: Mental Component Summary; PO: postoperative; m: month; y: year. ^aThe value represented the result of the Kruskal–Wallis H test for ranked data between 2 groups. ^bThe value represented the result of Student’s t test for continuous variables between 2 groups. ^cThe value represented the result of Fisher’s exact test for discontinuous variables between 2 groups. The bold value means that indicates significant differences.
