We performed one-stage bilateral THA for hemophilic patient and I would like to report the results of the case. A 61-year-old male had been diagnosed with mild hemophilia A as a neonate. He had severe pain in both hips and moderate pain in both knees. His hips were ankylotic and had no mobility. Uncemented simultaneous bilateral THAs were performed under general anesthesia. This case suggests that one-stage THA can be a good option for hemophilic hips, provided that sufficient substitution therapy is used.展开更多

A 61-year-old male had been diagnosed with mild hemophilia A as a neonate. He had severe pain in both hips and moderate pain in both knees. His hips were ankylotic and had no mobility. Uncemented simultaneous bilateral THAs were performed under general anesthesia. This case suggests that one-stage THA can be a good option for hemophilic hips, provided that sufficient substitution therapy is used.
