Haemophilic arthropathy of the knee: a surgeon's nightmare

Surgical management of knee synovitis secondary to mild haemophilia, without any significant previous medical history and an adverse family history of haematological disorders, is arduous. Due to its rare occurrence, the diagnosis is often delayed or sometimes missed, leading to the grave and often lethal consequences in intraoperative and postoperative periods. Hardly isolated knee arthropathy due to mild haemophilia has been reported in the available literature. In this report, we present the management of a case of a 16-year-old male with isolated knee synovitis with undiagnosed mild haemophilia, who came to us with the first episode of knee bleeding. We elucidate the signs and symptoms, investigations, surgical management, and difficulties faced, especially during the postoperative period. This case report is presented to enhance awareness of the existence of this disorder and its management to prevent postoperative complications.
