GARCIA-DOBARGANES BARLOW, FE; NEGRETE-CORONA, J  y  DIAZ-TOVAR, AA. Cemented polyethylene insert in a well fixed Total knee replacement. Case report. Acta ortop. mex [online]. 2016, vol.30, n.5, pp.259-263. ISSN 2306-4102.

We present the case of a 94 years- old patient, which was operated 14 years ago of a right total knee replacement for osteoarthritis, actually she suffers of pain and instability; her X ray shown polyethylene wear without loosening of the metal components. The polyethylene insert is not manufactured anymore so we decided cement a new polyethylene insert on the native tibial baseplate. The two years follow up show us a patient asymptomatic, good function and no radiolucencies on the tibial component. We only found a similar case report in Madrid and we believed that this decision, taken from total hip revisions, will succeed.
