Abstract

Total knee designs have evolved to allow more motion with compromising stability. The purpose of this study is to compare standard congruency and anterior lipped liners' effects on patient reported outcomes after TKA. 68 patients were retrospectively reviewed, and their SF-12 and KOOS scores were assessed preoperatively and one year post-operatively. Two-sample t-tests were used to compare differences between groups. The CVD design had a statistically significant greater improvement in KOOS-Pain compared to CVD+. No statistical difference was observed in the outcomes. The results may suggest that higher congruency designs lead to less physiological joint kinematics and pain.
