The ADVANCE® Unicondylar Knee System components are for single use only. The ADVANCE® Unicondylar Knee System components are for cemented use only. # B. DEVICE DESCRIPTION The ADVANCE® Unicondylar modular metal-backed tibia is part of the ADVANCE® Unicondylar Knee System that was previously submitted and cleared under 510(k): K012591- ADVANCE® Unicondylar Knee System. Wright Medical Technology is now enhancing the ADVANCE® Unicondylar Knee System by adding a modular titanium metal-backed UHMWPE tibial component. The ADVANCE® Unicondylar Knee System now contains the following components; Co-Cr femoral component, all-poly ultra-high molecular-weight polyethylene (UHMWPE) tibial component and modular titanium metal-backed UHMWPE tibial component. The ADVANCE® Unicondylar femoral component is identical to the femoral component previously submitted and cleared under ADVANCE® Unicondylar Knee System -510(k): K012591. The ADVANCE® Unicondylar all-poly tibial component is identical to the all-poly tibial component previously submitted and cleared under ADVANCE® Unicondylar Knee System - 510(k): K012591. The ADVANCE® Unicondylar modular metal-backed tibial base is manufactured from The ADVANCE® Unicondylar modular tibial insert is titanium (ASTM F136). manufactured from the identical UHMWPE as the ADVANCE® Unicondylar all-poly tibial components (510(k): K012591). The profile and sizing (Sizes 1, 2, 3 & 4) of the ADVANCE® Unicondylar modular metal-backed tibial components are identical to the ADVANCE® Unicondylar all-poly tibial components (510(k): K012591). The cement interface for the ADVANCE® Unicondylar modular metal-backed tibial components consist of a peripheral dovetail and two pegs and is substantially equivalent to the cement interface of the ADVANCE® Unicondylar all-poly tibial components (510(k): K012591). The articulating surface is identical for both the ADVANCE® Unicondylar modular metal-backed tibial insert and the all-poly tibial component (510(k): K012591). The locking mechanism for the ADVANCE® Unicondylar modular metal-backed tibial components is substantially equivalent to the ADVANTIM® Unicondylar modular metalbacked tibial components (510(k): K881779). Table 1 is a comparison chart summarizing the above design features for the ADVANCE® Unicondylar modular metalbacked tibial components.
