Abstract:
Objective To evaluate the effect of contralateral knee pain on joint dysfunction and treatment satisfaction on the operative side 1 year after total knee arthroplasty(TKA)in patients with osteoarthritis.Methods From March 2019 to Jan-uary 2021,635 patients underwent TKA including 296 males and 339 females,with an average age of(69.33±9.38)years old,the duration of symptoms was(1.15±0.44)years.According to the degree of pain visual analogue scale(VAS)in the contralat-eral knee joint 12 months after operation,the patients were divided into three groups,423 patients with no or mild pain(VAS 0 to 3),105 patients with moderate pain(VAS 4 to 6),107 patients with severe pain(VAS 7 to 10).The related factors of knee function and satisfaction score 12 months after operation were analyzed and compared on different contralateral knee pain lev-els.Results The contralateral knee pain VAS was significantly reduced after TKA.Old age,high body mass index,high WOM-AC scores of postoperative knee joint,moderate and severe pain of contralateral knee joint were the risk factors of dissatisfac-tion(P＜0.05),OR were 1.285,1.665,2.319,1.863 respectively.The high degree of knee pain on the operation side and the ladder room in the home environment were the risk factors for the high WOMAC scores 1 year after discharge(P＜0.05).Adher-ence to exercise and functional training after discharge were the protective factors for patients with high WOMAC scores 1 year after discharge(P＜0.05),OR were 3.016,1.738,0.619,0.574 respectively.Conclusion TKA can alleviate the pain of con-tralateral knee joint.Contralateral knee pain does not affect the WOMAC scores after TKA,but it will reduce the treatment sat-isfaction of patients.
