Abstract

We report 3 cases of early failure associated with AMK total knee arthroplasties with the use of Hylamer-M spacers. In 2 of these cases, massive osteolysis of the posterior condyles was noted; revision with the use of allograft bone to fill in the cavitary defects yielded excellent results. In all cases, large areas of pitting and delamination of the Hylamer spacers were noted. Given these cases and the previous literature on early failure of hip arthroplasties with Hylamer inserts, we recommend caution in using Hylamer for knee arthroplasty surgery.
