Kim SC, Lim YW, Jo WL, et al. - In this study, the long-term total hip arthroplasty (THA) outcomes in patients with osteonecrosis of the femoral head (ONFH) following allogeneic bone marrow transplantation (BMT) for the hematological disease were explored. Researchers distinguished all individuals who had undergone THA for osteonecrosis after BMT from 1997 to 2012 at 2 institutions. Applying propensity scores, they compared 75 THAs in 45 patients for age, gender, body mass index, 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). At 11-year follow-up, this large cohort multicenter survey displays that contemporary cementless THA in young hematological disease patients after allogeneic BMT is not correlated with a higher risk for surgical complications, revision, reoperation, readmission, and mortality in comparison with a matched cohort of idiopathic ONFH.
