Total knee arthroplasty in human immunodeficiency virus-infected hemophiliacs.

Twenty-six knee arthroplasties were performed in 15 patients with hemophilia A and human immunodeficiency virus infection from 1984 to 1991. Patient age range was 27 to 48 years. After an average follow-up period of 6.4 years (range, 1-9 years) all patients were alive and none of the implants had become infected. T4 lymphocyte counts showed some deterioration, which was not clinically significant. All of the patients were improved following surgery. Nineteen implants were rated excellent, four good, and three fair. Infection with human immunodeficiency virus did not adversely affect the clinical outcome of knee arthroplasty at follow-up periods up to 9 years.
