Cementless Unicompartmental Knee System

The column reinforcement design, with precise size
control, ensures immediate stability. Test verification
shows that after implantation, the femoral condyle
prosthesis exhibits high resistance to pull-out, ensuring
excellent initial stability.

Compared to competitors, HAROLD MEDI LLC precisely controls the keel size of the cementless uni-knee and optimizes the keel processing instruments, ensuring initial stability while effectively reducing the risk of tibial tray fractures.

The right image shows that compared to competitor cementless tibial tray, the imting force of the HAROLD cementless tibial tray is reduced by 40%, while the pull-out for remains almost unchanged. Implanting force represents the fracture risk around the prosthesis, while pull-out force indicates the initial stability of the prosthesis.
