The posterior stabilized VEGA Knee System was developed to fulfill the modern-day requirements of patient and surgeons for a modern knee implant system. The following objectives were considered in its design:

Natural kinematics through a rollback and a pivotal motion around the medial condyle During flexion, the natural knee shows increased rollback of the femur on the lateral side while the femur rotates around the medial center.[1] The asymmetric cam design of VEGA facilitates this lateral rollback and medial rotation, and therefore enables a natural pivotal motion.[2]

Stability even in high flexion Based on the design and the position of the PS box and post, the contact point of the box and post move distally with an increase of flexion. Therefore the increased jumping distance in flexion can reduce the subluxation risk. The synchronized contact surfaces between the articulating comp...
