Objective To explore the clinical study of TKA treated severe flexion deformity knees.Methods Collect 32 patients with severe flexion deformity knees from November.1997 to May.2009 in Ningxia People's hospital. Filtering out> 60°and no surgical contraindications were 32 patients included in the study,24 cases of rheumatoid arthritis, of which 20 cases knees, one knee in 4cases, a total of 44 joints. ankylosing spondylitis were 4 cases for the 8 knees.

There was statistical difference (P < 0.01) Among them, According to the HSS score, 14 patients (43.75%)were rated as excellent, 8 good (25.00%) ,8 fair (25.00%) and 2 Poor efficacy (6.25%),the choiceness rate was 68.75%.Conclusion After careful preparation of preoperative and setting individualized operation schemes. Osteotomy combined with the release of contracted soft tissues in the operation. Giving the rehabilitation training or management of standardize of after surgeries, satisfactory outcome could be obtained in patients with severe flexion deformity knees who underwent total knee arthroplasty.
