Abstract Objective To investigate the Methods and clinical Results of total knee arthroplasty (TKA) in patients with severe knee deformity. Methods From February 1999 to December 2012,916 patients (1031 knees) underwent TKA in this hospital,including 80 patients with severe knee deformity,of which,56 patients (70 knees) were followed up,among them,19 patients (23 knees) with varus knee deformity,21 patients (27 knees),patients with severe flexion deformity were 16 patients (20 knees) knee flexion deformity.The mean follow-up period was 60 months(ranging from 6 months to 10 years).To evaluate the outcomes of TKA at the time of pre-operation and follow-up respectively,range of motion(ROM),the HSS score and the KSS score were used.Results The average ROM improved from 80°(0°-120°) preoperatively to 115°(0°-130°) postoperatively.The HSS score and the KSS score were significantly improved compared with pre-operation(P<0.05). KSS improved from 33 points (10-68 points) preoperatively to 81 points (70-100 points),HSS improved from 43 points (27-68 points) preoperatively to 86 points (72-100 points). Varus knee deformity,valgus knee defoimity and flexion deformity were corrected. Conclusions TKA improves the function of knee effectively and the quality of patients' life. The effect of TKA is satisfactory.
