But satisfaction after TKA has not yet been reported in Kashin-Beck disease (KBD). We aim to examine satisfaction and clinical efficacy of TKA in the treatment of OA and KBD.Methods: Retrospectively review of 37 KBD patients (45 knees) and 52 OA patients (58 knees) who underwent TKA from January 2015 to January 2017. Data of outcome measures such as Knee Society knee score (KSKS) and function score (KSFS), Western Ontario and McMaster Universities Arthritis Index (WOMAC), and radiographic evaluation were collected preoperatively and during the last follow-up. Satisfaction was compared using the 2011 Knee Society Scoring System.Results: There were no differences in age, gender, BMI and Follow-up time. KBD patients had significantly worse preoperative range of motion, KSKS, and mechanical lateral distal femoral angle (mLDFA) compared with OA patients (P < 0.05). At the last follow-up, the KSKS, KSFS, WOMAC score, and radiographic parameters of all patients significantly improved (P < 0.05), but the satisfaction was higher in KBD patients than in OA (P < 0.05). Further analysis showed that KSFS, WOMAC total, pain, stiffness, and function scores were significantly worse for KBD (P < 0.05).Conclusion: Patient satisfaction was greater but clinical outcomes were inferior in KBD than in OA. This study also demonstrated that TKA is an effective surgical procedure for KBD, but how to improve functional outcomes needs to be further studied.Keywords: Kashin-Beck disease, osteoarthritis, total knee arthroplasty, satisfaction
