Abstract Objective To explore the clinical effect of lateral approach combined with lateral femoral sliding osteotomy in valgus knee.Methods Retrospectively reviewed 22 patients diagnosed as valgus knee were treated with total knee arthroplasty by lateral approach combined with lateral femoral sliding osteotomy at Luoyang Orthopedic-Traumatological Hospital from February 2016 to April 2018.There were 6 males and 16 females.The patients aged from 58 to 78 years，with an average age of(67.5±7.9) years.The surgical time，perioperative blood loss，length of hospital stay，complications were recorded，and the radiographic anteroposterior view of the knee and clinical outcomes at last follow-up were compared with that before surgery.Results All patients were inserted with posterior stabilized(PS) prosthesis.No constrained and hinged prosthesis were used.The surgical time was(90.2±12.3) min，and the intraoperative blood loss was(150.0 ±34.7) ml.The followed up time was 24 to 63 months(mean，40.2±10.7 months).Preoperative knee society score(KSS)，Western Ontario McMaster Universities(WOMAC)，and range of motion(ROM) were(45.5±10.3)，(77.1±9.7)，(77.3±6.3) °，respectively.Preoperative hip knee ankle angle(HKA) and mechanical lateral distal femoral angle(mLDFA) were(193.6±7.5) °，(97.0±3.1) °，respectively.The KSS，WOMAC，ROM at last follow-up were(90.3±10.6)，(37.6±7.5)，(110.0±6.3) °，respectively，which were significantly better than those of pre-operation(P＜0.05).The postoperative HKA and mLDFA were(181.4±2.6) °，(87.5±2.9) ° respectively，which were significantly improved than those of pre-operation(P＜0.05).Conclusion Lateral approach combined with lateral femoral sliding osteotomy is effective in the treated with valgus knee，without the needed of high grade of constraint of the implant during TKA.
