Resection arthroplasty as a salvage procedure for a knee with infection after a total arthroplasty

Between 1970 and 1983, resection arthroplasty was done as a salvage
procedure for twenty-eight knees (twenty-six patients) with infection after
total arthroplasty. Eleven patients had multiarticular rheumatoid
arthritis; fourteen, osteoarthritis; and one, multiarticular neuropathic
arthropathy. Systemic signs of infection were eliminated in all patients
and local signs, in 89 per cent of the patients. After resection
arthroplasty alone, fifteen patients were able to walk independently. Six
patients with monoarticular osteoarthritis who found the resection
arthroplasty to be unacceptable had a successful secondary arthrodesis. In
three patients a spontaneous bone fusion developed after the resection,
with the knee in a good position. Two patients who were unable to walk
before the resection arthroplasty were still unable to do so
postoperatively. Neither the patient's disease nor the type of prosthesis
that had been used was a reliable predictor of success of the resection
arthroplasty. The patients who had had the most severe disability before
the total knee arthroplasty were most likely to be satisfied. Patients who
had had less disability were more likely to find the results of resection
arthroplasty to be unsatisfactory.
