Unicondylar knee prosthesis UNI KROMA ®

fixed-bearingcemented or non-cementedleft

UNI KROMA® is an anatomical, fixed-bearing, unicompartmental prosthesis. The tibial component is available in a metal-backed version (cemented or uncemented) and an all-polyethylene (all PE) version. Fitting may be performed using a conventional technique or with custom instrumentation. The instrumentation is original in that it is HYBRID. Characteristics : The UNI KROMA® prosthesis is anatomical as it is comprised of a femoral component, a tibial baseplate and an insert which are asymmetrical: Internal Left/External Right or Internal Right/External Left. The femoral component and tibial baseplate are available in 6 sizes. For the metal-backed version, the insert is available in 6 sizes and 4 thicknesses. The all-PE baseplate is available in 6 sizes and 5 thicknesses. Materials : Cemented and cementless femoral component: Cobalt Chrome (CoCr) with dual coating for the cementless version (Titanium spray T40 + HA). Cementless tibial baseplate: Titanium (TA6V) with dual coating (Titanium spray T40 + HA). Cemented tibial baseplate: Cobalt Chrome (CoCr). All-PE baseplate and insert: Polyethylene. INSTRUMENTS The instrumentation is called “hybrid” because it combines metallic parts and disposable polyamide parts (Single Use). The technique of fitting with tailor-made instrumentation makes it possible to make the tibial cuts AND the distal femoral cut. INDICATIONS The UNI KROMA® prosthesis is an unicompartmental prosthesis which is recommended in the following cases : Primary or secondary isolated osteoarthritis of the internal or external femorotibial compartment of the knee; Isolated necrosis of the internal or external condyle of the knee.
