Early Efficacy Evaluation of Unicompartmental Knee Arthroplasty and Total Knee Arthroplasty in the Treatment of Knee Osteoarthritis
Objective To evaluate the early efficacy of unicompartmental knee arthroplasty(UKA)and total knee arthroplasty(TKA)in the treatment of knee osteoarthritis.Methods From June 2020 to February 2022,77 patients with knee osteoarthritis who met the surgical treatment in Qitai Hospital of the Sixth Division of Xinjiang Production and Construction Corps were included.According to different treatment methods,they were divided into UKA group(n=35)and TKA group(n=42).UKA group was treated with UKA,and TKA group was treated with TKA.The clinical indexes(operation time,intraoperative bleeding,postoperative drainage volume,hospitalization time),knee joint pain and activity[Visual Analogue Scale(VAS),range of motion(ROM)],prognosis(WOMAC score)and economic burden were compared between the two groups.Results The operation time and hospitalization time of UKA group were shorter than those of TKA group,and the intraoperative bleeding and postoperative drainage volume were less than those of TKA group,but the differences were not statistically significant(P＞0.05).The VAS score of the two groups after operation was lower than that before operation,and the ROM was higher than that before operation,while the VAS score and ROM of the UKA group were lower than those of the TKA group,and the differences were statistically significant(P＜0.05).The WOMAC score of the two groups at 1 week,1 month,3 months,6 months and 12 months after operation was lower than that before operation,and the WOMAC score of the UKA group at 3 months after operation was lower than that of the TKA group,the differences was statistically significant(P＜0.05).The total cost score of the UKA group was lower than that of the TKA group,and the material cost of the UKA group was lower than that of the TKA group,the difference was statistically significant(P＜0.05).Conclusion UKA has better advantages in relieving pain,reducing WOMAC score and reducing economic burden in patients with knee osteoarthritis in the early stage,while TKA can better restore the knee joint activity of patients.Therefore,the difference of prognosis and economic conditions of patients should be comprehensively evaluated before selecting the appropriate surgical method.
