20th Year of Medial Pivot Video 1 2

Due to the high stability and rotation provided by the partial ball-in-socket articulation, the ADVANCE® Medial-Pivot Knee functions like a normal knee. In fact, studies have shown it is preferred by 8 out of 10 patients with an ADVANCE® Medial-Pivot Knee in one leg and a competitive design in the other. In the normal knee, the medial femoral condyle exhibits less roll than the lateral condyle during motion. The ADVANCE® Medial-Pivot Knee was the first major system to address and replicate these kinematics. Medial-pivoting kinematics is a critical design rationale, which has grown through the acceptance of modern kinematic studies and clinical success. Constant radius from 0° - 90° High contact area throughout ROM Maintains constant ligamentous tension throughout range of motion Patella track at anatomic angle and depth Does not require a large intercondylar resection Raised anterior lip Replaces the spine of a traditional posterior stabilized knee Allows PCL-substitution Lateral trough Allows 15° of natural rotation for deep flexion Allows freedom of rotational alignment Ball-in-socket articulation Provides patient stability through range of motion Highest contact area through range of motion
