Objective To investigate the clinical effect of total knee arthroplasty(TKA)in patients with severe varus deformity of knee.Methods Twenty-one patients with severe varus deformity of knees were treated with TKA.AKS score of knee joint function,hip-knee-ankle angle(HKA),and knee flexion range of motion(ROM)were compared before and after arthroplasty.Results All cases were followed up for 2～7 years.The postoperative pain was signifi-cantly reduced or completely eliminated,and X-ray examination showed that the knee varus deformity was effectively corrected.At the last follow-up,the HKA,knee flexion ROM,and AKS scores were all greater(higher)than before surgery(P＜0.05).Conclusions TKA for severe varus deformity of knee is satisfactory with lower limb alignment correction,joint activity recovery is good,and function is satisfactory.
