Mechanical stability of well-functioning tibial baseplates from postmortem-retrieved total knee arthroplasties.

In joint replacement, cyclic motion at the bone-prosthesis interface is considered a precursor to component loosening. This study characterized the mechanical stability of 13 total knee arthroplasties harvested postmortem after an average time in situ of 10.3 years. With loads applied to the medial and then the lateral tibial plateau, motion between the… CONTINUE READING
