Total Hip Arthroplasty in Human Immunodeficiency Virus Positive Patients: A Systematic Review of Outcomes.

Total hip arthroplasty (THA) has become a common intervention for Human Immunodeficiency Virus (HIV)-positive patients who have osteonecrosis of the femoral head. This paper provides a systematic review to assess survivorships, patient-reported outcomes (PROMs), infection rates, other complications, and immune competence for patients who had THAs who did and did not have HIV. A comprehensive and systematic review of published studies investigating the outcomes of THA in HIV-positive patients (osteonecrosis and non-osteonecrosis patients) was performed adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 10 studies with 9,534 HIV-positive patients fulfilled the inclusion and exclusion criteria. Manuscript quality was assessed on two scales: the Coleman Methodology Score and the level of evidence derived from Centre for Evidence-Based Medicine criteria. Data was extracted from studies in the five key areas of interest: survivorships; PROMs; infection rates; complications; as well as clusters of differention-4 (CD4+) counts and viral loads (VL). Implant survivorship was between 95 and 100%. Postoperative Harris Hip Scores were significantly improved from preoperative values in HIV-positive patients. Postoperative PROMs and infections did not appear to be different between HIV-positive and HIV-negative patients. Many of the cohort studies demonstrate comparable complication rates to matched controls. Where described (7 reports), mean CD4+ counts ranged from 425 to 646 cells/mm Total hip arthroplasty (THA) is an effective treatment for HIV-positive patients, many of whom suffer from osteonecrosis of the femoral head. The results demonstrate excellent implant survivorship, improved quality of life, and a low risk of infections and complications.
