K-‐MOD R EV:

The modular revision knee arthroprosthesis K-‐MOD REV consists of several elements such as the femoral

component, the tibial tray, the meniscal insert, the locking screw for fixed bearing, the patellar component

and the diaphyseal femoral and tibial stems. The diaphyseal stem must be assembled to the tibial and

femoral components directly or via offset adapters, with relative locking headless screw. The

arthroprosthesis K -‐MOD R EV i s a vailable i n d ifferent p rosthetic d esign, a ll f ixed b earing:

•

•

Some filling tibial and femoral thicknesses (wedge) are also available with relative locking screws. The

femoral component and the tibial tray are only available in cemented version and diaphyseal stems only in

cementless v ersion. E ach o f t hese 3 m odels i s a lso r ealized i n a n a nallergic v ersion w hich i s c haracterized b y
