The Tahoe Unicompartmental Knee System (TUKS) is designed as a system and is not intended for substitution of components from other systems. The indications for use are as follows: Primary medial or lateral compartmental intervention of (1) primary non-inflammatory degenerative disease, including osteoarthritis, traumatic arthritis, or osteonecrosis; (2) posttraumatic degenerative disease; (3) varus or valgus deformities; and (4) damage due to previous surgical intervention when the opposite compartment is preserved and when the anterior cruciate, posterior cruciate, medial collateral, and lateral collateral ligaments are present and functional. All TUKS implants are single use only, and are intended for implantation only with bone cement.

The Tahoe Uni Knee System (TUKS) is a primary fixed-bearing, round-on-flat unicompartmental knee system offering flexibility to restore function in the affected medial or lateral tibial compartments. The femoral and tibial components are intended use only. The femoral component is made from cast CoCr alloy (ASTM F75), whereas the tibial baseplate is made from wrought CoCr alloy (ASTM F1537).

The VitalitE Tibial Insert is a vitamin E version of the UHMWPE tibial insert that has been a component of both the Consensus Knee System (CKS) and the Consensus Revision Knee System (RKS). The new insert still serves as the gliding surface between the metallic femoral component and the metallic tibial base plate of these knee systems. The new VitalitE insert will also be available in a cruciate retaining (CR) or ultra-congruent/ PCL substituting designs in sizes 0 through 6 and in thicknesses from 10 to 22 mm. The proprietary locking mechanism design on the underside of the insert will remain unchanged. The only difference will be the vitamin E additive in the UHMWPE which is a-tocopherol. This is the exact same polymer that is used in the Consensus VitalitE Acetabular insert but with a slightly lower radiation dose. Consensus will also offer our current CKS all-poly patellae in the new vitamin E UHMWPE material. This includes both the round and oval configurations with either a 7.5 mm or 10 mm thickness.

The UniSyn Hip System was originally cleared as a modular hip system for Hayes Medical under the name "Triton", modifications to the system were cleared in a subsequent submission by Hayes under the UniSyn name. Hayes Medical changed its name to Consensus Orthopedics in 2008. This system consists of three primary components: the neck, the body, and the stem. This submission is to addition of a set of modified ("Plus") stems. These minor modifications in body thickness are designed to allow for better contact between the implant and the inner surface of the medullary canal during revision surgery. The sizes of stems offered with the modified design are within the ranges previously cleared for the UniSyn system. The Plus stems are offered in neutral or +1 mm styles, short or long, in 10 to 20 mm diameters, and lengths from 110 to 210 mm. There is no change to the manufacturing, packaging, or sterilization processes. This change will not affect the indications for use nor any of the labeling.
