Summary

The overall purpose is to compare the kinematics and mechanics of medialized dome and anatomic resurfacing through measurement and simulation, and to correlate these findings with patient satisfaction and performance.

Aim 1: Comparison of patellofemoral kinematics between dome and anatomic implant designs using stereo radiography and correlation with patient function as measured by Knee injury and Osteoarthritis Outcome score, Knee Society score, and strength.

Hypothesis: the anatomic patellar implant will have significantly greater sagittal flexion than the dome implant.

Aim 2: Comparison of dome and anatomic moment arm, quadriceps efficiency, patellar contact mechanics and loading through the use of subject-specific simulation.

Hypothesis: quadriceps efficiency and moment arm will be greater for the anatomic patellar implant, while loading between the patellar and femoral components will be reduced.
