Arthrodesis of the knee following failed total knee arthroplasty
MP Brodersen, RH Fitzgerald, LF Peterson, MB Coventry and RS Bryan
In forty-five patients, who had an arthrodesis because of failed total knee
arthroplasty, the cause was infection in forty, instability in two, failure
of the prosthesis in two, and loosening in one. The arthrodesis succeeded
in twenty-nine (81%) of thirty-six patients who had had a minimally or
partially constrained arthroplasty and in five (56%) of nine who had had a
hinge-type prosthesis inserted. The reasons for failure were severe bone
loss, persistent sepsis, and loss of bone apposition after manipulation.
The technique of arthrodesis did not seem to influence the final result.
External fixation most commonly had to be used because of the infections
and the device was kept in place for an average of ten weeks, after which
immobilization in a cast was used until the arthrodesis healed.
