Late Onset Metallosis after Revision Total Knee Arthroplasty with Metal-Backed Patellar Component In Situ.
We describe a small case series with severe metallosis after revision total knee arthroplasty (TKA) due to metal-backed patellar component failure. Metallosis is a rare complication after TKA, which may cause systemic and local symptoms. ⋯ Based on these cases, we recommend performing regular checkups in case of a metal-backed patellar component to detect metallosis in an early stage, to prevent extensive revision surgery. Moreover, we recommend applying a low threshold to revise a metal-backed patellar component because of the severe consequences of metallosis that might occur.
