Abstract | INTRODUCTION: AIM: To identify the risk factors for increased PBL by incorporating coagulation factor levels following TKA in patients with haemophilic arthropathy. METHODS: A total of 92 TKA (78 haemophilia A and 14 haemophilia B) were performed for haemophilic arthropathy. PBL was calculated using the haemoglobin (Hb) balance method, and patients were categorised into two groups: group H (higher blood loss than the mean PBL, n = 36) and group L (lower blood loss than the mean PBL, n = 56). Body mass index (BMI), operation day Hb, haematocrit and coagulation factor level (VIII or IX) were analysed, including demographic and laboratory data. RESULTS: The mean PBL volume during TKA for haemophilic arthropathy of the knee was 542.3 ± 361.7 mL. Multivariate analysis revealed that lower haematocrit on the operation day (odds ratio [OR], .633; 95% confidence interval [CI], .511-.786; p < .001) and coagulation factor level (OR .970, CI .941-.999; p = .046) were independent risk factors for increased PBL. Receiver-operating characteristic analysis identified these cutoff values for predicting increased PBL: operation day coagulation factor level 93.5% (sensitivity, 70.4%; specificity, 67.6%) and haematocrit level of 38.2% (sensitivity, 85.7%; specificity, 80.6%). CONCLUSIONS: The PBL increased as haematocrit and coagulation factor levels decreased on the operation day. A coagulation factor level <93.5% or haematocrit level of <38.2% may be a significant risk factor for increasing PBL. LEVEL OF EVIDENCE: Level IV, Case Series, Treatment Study.
