Figure 1: Metal-Back Design.
Figure 2: All Polyethelene design.
Figure 3: The tibial components are made from cobalt chromium molybdenum alloy.
Six sizes are available for both the left and right side, for maximum coverage on tibial bone cut and to avoid anteriomedial overhang, which sometimes caused postoperative pain in the Phase 2 design.
Figure 4: The femoral components (single radius design) are made of cast cobalt chromium molybdenum alloy for strength, wear resistance and biocompatibility. The design is available in 5 sizes.
Figure 5: The articulating surface of the femoral component is spherical and polished to a very high tolerance.
Table 1: UKA indications.
Figure 6 A-B: Demonstrates a case of OA which underwent open reduction and internd fixation due to excessive bone loss.
