    This study compared kinematics of ultra-congruent and medial-congruent total knee arthroplasty using dynamic radiostereometric analysis.

  • 2

    The cohort consisted of 16 patients, with 8 receiving medial-congruent and 8 receiving ultra-congruent designs after randomization.

  • 3

    At follow-up, the medial-congruent group demonstrated significantly greater range of motion compared to the ultra-congruent group.

  • 4

    Both groups exhibited a medial pivot pattern, but no significant differences in compartment translation range were found.

  • 5

    The study concluded that there were no kinematical differences between ultra-congruent and medial-congruent designs under mechanical alignment.
