balanSys® UNI

When arthritis occurs on only a single condyle, a unicondylar knee replacement may be indicated. A unicondylar implant selectively resurfaces the affected compartment, while keeping the opposite/healthy compartment intact. Mobile-bearing technology allows an ultra-high molecular weight polyethylene insert to articulate with both the femoral and tibial components. The mobile-bearing BalanSys™ UNI, developed in collaboration with HSS’s surgeons Russell Warren, MD, and Thomas Wickiewicz, MD, and Mathys Medical LTD, was designed to recreate normal kinematics of the knee joint while reducing stresses in the polyethylene insert.
