Abstract

Revision of a total knee replacement because of medial tibial plateau insufficiency revealed the base plate of a noncemented plastic-peg tibial component to have sheared off the plastic pegs which were still tightly embedded in bone. The fact that these plastic pegs remained tight indicates that even in extremely adverse situations the pegs are capable of providing fixation.
