Mobile-Bearing posterior stabilized

ACS® MB PS system

The ACS® MB PS system (PS-posterior stabilized) is used for the functional replacement of the posterior cruciate ligament. The presence of the femoral spindle and the PE-peg results in a posterior stabilization of the knee joint during articulation between femoral and tibial component. The PE-insert can be combined with both primary tibial components.
