title: [Extensor mechanism allograft reconstruction after total knee replacement].
abstract: We present three cases in which we used a complete extensor mechanism allograft for the reconstruction of an insufficient extensor mechanism after total knee arthroplasty (and failed reconstruction with local tissue in two of these cases). Early results are encouraging. Allograft reconstruction can be taken into consideration as an alternative to arthrodesis in those "worst-case scenarios". Late failure may occur in about 20%, probably due to a lack of revitalisation in the centre of the allograft.
