Effect Of Metabolic Syndrome On The Results Of Total Knee Arthroplasty In Patients With Knee Osteoarthritis

Objective:Objective to explore the effect of metabolic syndrome on the outcome of total knee arthroplasty in patients with knee osteoarthritis.Methods:The total knee arthritis(KOA)patients who underwent total knee arthroplasty(KOA)in the orthopedic first ward of Henan University People’s Hospital from September 2018 to October 2020 were selected as the subjects.A total of 175 patients were divided into two groups,group A(114 cases)without metabolic syndrome(Met S)and group B(61 cases)with metabolic syndrome(Met S).During the study,3patients were terminated due to changes in their condition(2 patients without Met S and 1 patient with Met S).A total of 172 patients completed the process of this study.The general data of the two groups were compared,including the degree of knee joint pain(VAS score),swelling,postoperative drainage tube drainage,knee joint function(HSS score),and postoperative complications in hospital.Results:There was no significant difference in gender,age,operation side and operation time between the two groups(P > 0.05);The VAS scores of the two groups at different time points,such as before operation,24 h,48 h,72 h after operation,were compared.The VAS scores of the two groups at different time points after operation gradually increased and were lower than those before operation.There was no significant difference in the VAS scores at 24 h after operation(P > 0.05).The VAS scores of group B before operation,48 h,72 h after operation were higher than those of group A(P < 0.05);The swelling degree of the affected limb at different time points after 6,12,24,48 and 72 hours was compared between the two groups;The swelling degree of affected limb in group B was higher than that in group A at 6,12,24,48 and 72 hours after operation(P < 0.05);The drainage volume of the two groups at different time points such as 6,12,24 and 48 hours after operation was compared.The increase of drainage volume of the two groups decreased gradually.The drainage volume of group B at different time points after operation was greater than that of group A,and the difference was statistically significant(P < 0.05);The HSS scores of the two groups at different time points before operation,3 months and 6 months after operation were compared;The HSS score of group B at each time point after operation was lower than that of group A,and the difference was statistically significant(P < 0.05).The incidence of postoperative complications of group B was higher than that of group A,and the difference was statistically significant(P < 0.05).Conclusion:MetS aggravates the degree of knee joint pain(VAS score)and swelling after TKA in KOA patients,increases the drainage volume of postoperative drainage tube and the incidence of postoperative complications,and reduces knee joint function(HSS score),which leads to the occurrence of adverse results after TKA in KOA patients.
