This was a late-70s gentleman who presented with knee pain related to his total knee replacement, which he’d had since 2005. Imaging showed narrowing of the poly insert and physical exam showed laxity and minor instability. Upon opening the knee, it was discovered that he had metalosis related to prosthesis break down. The synovial fluid was full of tiny metal shavings and the surrounding tissues were stained black. The prosthesis was successfully removed and replaced, which took about 5 hours due to complexity.
