A Novel Case of Recurrent Hemarthrosis Following Knee Arthroscopy in a Patient with Undiagnosed Hemophilia

Abstract The purpose of this study was to raise awareness and recommend management of a rare but morbid complication following knee arthroscopy: recurrent hemarthrosis in the setting of previously undiagnosed hemophilia. A 17‐year‐old male without prior personal or family history of bleeding disorders underwent an uneventful partial lateral meniscectomy and had several subsequent episodes of hemarthrosis beginning 10 days after surgery. This study helps to elucidate a strategy for diagnosis and management of this uncommon but morbid complication. A heightened level of suspicion for possible underlying coagulopathy and early involvement of the hematology service are of paramount importance in the management of patients with unexplained recurrent hemarthrosis following routine arthroscopic procedures.
