Seventy-six revised total knee arthroplasties (TKAs) performed for
mechanical, nonseptic failure of the primary arthroplasty in 62
rheumatoid arthritis patients were investigated. The revisions were
performed with McIntosh, Marmor, Attenborough, Guepar, and various
types of tricompartmental prostheses. Twenty-one of the 76 revisions
subsequently failed. Fifteen were mechanical failures and six were
deep infections. Thirteen of the 21 failures were treated with
another arthroplasty, six with arthrodesis, and two with antibiotics
only. After an average of 60 months, 48 of the surviving
arthroplasties were examined clinically and roentgenographically. At
follow-up examination, eight were clinical failures. One-half of the
McIntosh and Marmor arthroplasties and one-third of the Attenborough
and Guepar arthroplasties, altogether 17 cases, showed signs of
potential roentgenographic failure. The majority of the revised TKAs
classified as roentgenographic failures were clinically successful or
acceptable. Revision of TKAs in noninfected rheumatoid patients can
be performed with acceptable clinical results but with a
significantly higher failure rate than after primary procedures.
