Event Description

It was reported that the patient underwent a revision procedure approximately seven years post implantation due to swelling, pain, elevated levels of co and cr in his blood after which the knee was judged as unstable.During the revision thick gray/ black fluid was noted; the surgeon noted that hypermobility may have caused stress on the hinge possibly contributing to the patient's high cobolt chromium levels.The articular surface, hinge pin, and tibial bushing were removed and replaced.
