| Abstract: | Combined thrombo‐prophylaxis with mechanical and pharmacological methods is recommended in patients undergoing total knee or hip arthroplasty. As patients with ‘untreated inherited bleeding disorders such as haemophilia’ are at risk of bleeding, no prophylaxis has been prescribed for these patients. However, a retrospective study reported subclinical deep venous thrombosis (DVT) in 10% of patients with haemophilia undergoing major orthopaedic surgery. In this study, we aimed to evaluate the risk of DVT after total knee arthroplasty (TKA). We examined 38 TKA in 33 Japanese patients with haemophilia using ultrasonography. We did not detect DVT. The risk of DVT in patients with haemophilia after TKA may be lower than that in the general population. However, as patients with haemophilia progress in age, venous thromboembolism should be considered as a potential problem. |
