Despite this rarity, pre\u2010transfusion testing (blood typing, screening, and cross\u2010matching) has become routine. We sought to determine if such routine testing is necessary for patients who undergo a primary TKA or THA by (1) measuring the current rate of intraoperative transfusions in primary TKA and THA patients, (2) identifying risk factors for transfusions, and (3) calculating the costs of such blood typing and screening.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Methods<\/jats:title><jats:p>We retrospectively examined the records of 992 patients who underwent primary TKA, THA, or unicompartmental knee arthroplasty (UKA) to identify patients requiring intra\u2010operative or in\u2010hospital postoperative transfusions.
