Inferior results at long-term follow-up after extensor mechanism allograft reconstruction in septic compared to aseptic revision total knee arthroplasty

“

the key message of the paper is that the allograft technique for extensor mechanism ruptures has relatively good results. In the setting of an infection the allograft does not increase the chance of reinfecting the joint. From a functional point of view in front of a failed arthroplasty for infection and extensor mechanism insufficiencty the surgeon should counsel the patient that they will have a 50% change to get a satisfactory functional result. The alternative would be an arthrodesis
