Abstract
We evaluated the clinical and radiographic results of total knee arthroplasty in 141 cases using the bisurface type (KU) system. We followed them for a period of more than one year (average 31 months).
Their mean JOA score improved from 58.0 to 83.6 points and mean flexion angle improved from 121.8° to 122.1°.
However the results were satisfactory, they were worse than at post-operative one year or less.
