The management of infected total knee replacements

Abstract

A review of patients with an infected resurfacing prosthesis is presented. Eight patients with a loose infected prosthesis were treated by a one-stage exchange arthroplasty; six others with a well-fixed infected prosthesis were treated by drainage and antibiotics. All eight treated by exchange arthroplasty remained free of infection as did five of those treated by drainage. In four of these last five patients, the prosthesis was inserted without cement; the possible role of polymethylmethacrylate in the persistence of infection is discussed.
