Total Knee Arthroplasty in Human Immunodeficiency Virus Patients: A Literature Review.

Background: Total knee arthroplasty (TKA) has become a common surgical intervention for human immunodeficiency virus (HIV)-positive patients who develop osteonecrosis of the knee. This paper summarized existing literature regarding the outcomes of HIV-positive patients undergoing TKA in 4 subsections: (1) complications; (2) survivorship analyses; (3) patient-reported outcomes; and (4) infections. Methods: A review of PubMed was performed, searching for articles focused on HIV-positive patients undergoing TKA. There were 6 reports selected, containing 4765 HIV-positive patients, and data regarding the various domains was tabulated and analyzed. To ensure article quality, a methodology score and level of evidence were determined for selected studies. Results: Complication rates for HIV-positive patients were low, with a larger study reporting that 7.8% of HIV-positive patients developed a complication in comparison to 8% of HIV-negative patients. Survivorship analyses showed similar results, with a study reporting implant survivorship of 98% for HIV-positive and 99% for HIV-negative patients. There were no differences in patient-reported outcomes; HIV-positive patients improved from baseline with respect to the mean Knee Society objective and mean Knee Society functional scores, and the University of California, Los Angeles self-reported activity levels. The infection rate for HIV-positive patients was low, with a larger database study reporting that 0.6% of HIV-positive patients developed a wound infection in comparison to 0.4% of HIV-negative patients. Conclusions: A TKA is an effective treatment for HIV-positive patients who develop osteonecrosis of the knee. Results showed similar patient-reported outcomes, implant survivorships, revisions, and complication rates when compared to non-HIV patients.
