OBJECTIVE: To investigate clinical efficacy and experience of total knee arthroplasty in treating knee osteoarthritis patients with Parkinson's disease. METHODS: From January 2011 to January 2014, 19 knee osteoarthritis patients with Parkinson's disease treated with total knee arthroplasty were collected. Among them, including 9 males and 10 females aged from 61 to 83 years old with an average of 71.3 years old. Radiology results were checked before and after operation. VAS score and KSS score were applied to evaluate clinical effects. Patients were classified according to HoehnYahr grade, 3 cases in grade 1, 4 cases in grade 1.5, 2 cases in grade 2, 4 cases in grade 2.5, 2 cases in grade 3 and 1 case in grade 4. RESULTS: Nineteen patients were followed up from 3 to 7 years with an average of 4.3 years. The pain of patients was significantly reduced or disappeared. All incisions were healed at stage I. At the latest follow-up, 3 patients had knee pain, and mild pain in 1 patient, moderate in 1 patient without severe pain. VAS score was reduced from preoperative 8.4±1.3 to the latest follow-up 3.1±1.2, the difference was statistically significant (P<0.05). KSS score improved from 43.6±7.3 before operation to 91.8±10.6 after operation. The condition of Parkinson's were controlled by medicine. No loosening and subsidence of prosthesis by X-ray examination. CONCLUSIONS: Total knee arthroplasty is a safe and effective method for the treatment of Parkinson's disease and has satisfactory mid-term clinical effect. Copyright
