Prospective, Single-center, Non-randomized, Consecutive Series Study Comparing Functional Differences Between a Standard Posterior Stabilized TKR and a High-flexion Posterior Stabilized TKR
Prospective, Single-center, Non-randomized, Consecutive Series Study Comparing Functional Differences Between a Standard Posterior Stabilized TKR and a High-flexion Posterior Stabilized TKR
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 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.
