The therapeutic effect is replacement of the diseased joint with artificial components to restore joint function. The purpose of this submission is to introduce a line extension to the b-ONE™ MOBIO™ Total Knee System CR/CR PLUS Tibial Insert components and PS/PS PLUS Tibial Insert Components. Compatibility with the b-ONE™ MOBIO™ Total Knee System tibial baseplate and femoral components remains the same. There is no allowed interchangeability with systems manufactured by other companies. The subject b-ONE™ MOBIO™ Tibial Inserts are made from UHMWPE GUR® 1020-E Crosslinked with .1% tocopherol and conventional UHMWPE GUR® 1020. This material is the same as that used in the reference and predicate devices. The pre-assembled locking wire is the same locking wire used in the existing Tibial Inserts and is manufactured from Cobalt Chrome conforming to ASTM F90. All system components are supplied sterile and are single use devices.
