The purpose of this study is to evaluate the differences in clinical outcomes between the Optetrak® Posterior Stabilized (Optetrak® PS, Exactech, Gainesville, FL) and the Optetrak® Hi-Flex™ (Optetrak® HF, Exactech, Gainesville, FL) knee designs. The null hypothesis is that there is no difference in postoperative knee flexion between the Optetrak® PS and Optetrak® HF groups.
