Effect of Total Knee Arthroplasty on Range of Motion in Patients with Osteoarthritis
Objective:To explore the effect of total knee arthroplasty(TKA)on range of motion in patients with knee osteoarthritis.Methods:A total of 84 patients with knee osteoarthritis who received treatment in our hospital from September 2021 to August 2023 were selected,and were divided into the control group receiving arthroscopy and the observation group receiving total knee arthroplasty according to different surgical methods,with 42 cases in each group.The knee range of motion,osteoarthritis index(WOMAC)and inflammatory factor levels[tumor necrosis factor-α,TNF-α)and interleukin-1(IL-1)]were compared before surgery and at 4 weeks after surgery.Results:Preoperatively,there was no statistical difference in knee range of motion between the two groups(P>0.05).At 4 weeks after surgery,the flexion angle of the two groups increased and the extension angle decreased.The effect in the observation group was more obvious than that in the control group,with a statistical difference(P<0.05);There was no statistically significant difference in WOMAC scores between the two groups before surgery(P>0.05).At 4 weeks after surgery,WOMAC scores of both groups decreased significantly in the observation group compared with the control group(P<0.05);Preoperatively,there was a statistical difference in the levels of serum inflammatory factor between the two groups(P>0.05).At 4 weeks after surgery,TNF-α and IL-1 levels decreased in the two groups.The level in the observation group was significantly lower than that in the control group,with a statistical difference(P<0.05).Conclusion:Total knee arthroplasty(TKA)can increase the range of motion,improve osteoarthritis index and decrease the level of inflammatory factor.
