Kim SC, Lim YW, Jo WL, et al. - In this study, the long-term total hip arthroplasty (THA) outcomes were evaluated in patients with osteonecrosis of the femoral head (ONFH) following allogeneic bone marrow transplantation (BMT) for the hematological disease. Researchers distinguished all patients who had undergone THA for osteonecrosis after BMT from 1997 to 2012 at two institutions. They matched 75 THAs in 45 patients for age, gender, body mass index using propensity scores, American Society of Anesthesiologists score, and year of surgery with 75 THAs in 58 patients with idiopathic ONFH without a history of the hematological disease (1:1 ratio). This large cohort multicenter survey at 11-year follow-up exhibits that, after allogeneic BMT, contemporary cementless THA in young hematological disease patients is not correlated with a higher risk for surgical complications, revision, reoperation, readmission, and mortality in comparison with a matched cohort of idiopathic ONFH.
