Clinical affect of contralateral knee pain on patients undergoing total knee arthroplasty
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.
