BIORAD knee failed miserably at just 12 years!
52 yrs female
RA
bilateral TKR was done using BIORAD ORTHOVASIVE ( Indian) implants 13 yrs back.
Presented to us with severe Osteolysis around the tibial component, loosening, varus collapse and a stress fracture of the left proximal tibia.
We have already done revision of her rt knee for similar presentation at just 9 years !
Tibial component just walked out. There was extensive blackish metallosis and synovitis which required extensive synovectomy.
Femoral component was still holding on which required oscillating saw to remove it.
Did semi constrained revision using DePuy TC 3.
Used mobile bearing tibial tray + Uncemented metaphyseal sleeve + Uncemented extension rods on both sides.
