Perioperative care of a patient with refractory idiopathic thrombocytopenic purpura undergoing total knee arthroplasty.

Idiopathic thrombocytopenic purpura (ITP) is an autoimmune disorder leading to low platelet count and an increased risk of bleeding. Major joint replacement surgery in a patient with ITP can be associated with severe postoperative bleeding. We present our experience of perioperative management in a patient with severe refractory chronic idiopathic thrombocytopenic purpura who successfully underwent a cemented total knee replacement.
