Bi-compartmental Partial Knee Replacements
Inlay and Onlay Implants
(MAKO Surgical Corp.)
The bi-compartmental implant is designed to restore the natural function of the knee by replacing the damaged cartilage due to osteoarthritis in the medial (inner), patellofemoral (top), or both compartments of the knee. It is offered in two designs - inlay and onlay.
The inlay is comprised of three components:
The femoral component (affixed to femur bone), the patellofemoral component (also affixed to the femur bone) and the tibial component (affixed to the tibia bone).
The onlay is comprised of four components:
The femoral component, the patellofemoral component, the tibial base plate (affixed to the tibia bone), and the base plate insert (affixed to the tibial base plate).
Both of these components are implanted using a surgeon-interactive robotic arm system.
