Abstract: Objective To explore the risk factors of hidden blood loss after UKA.Methods A retrospec-tive study was conducted on 273 patients who underwent UKA from January 2015 to December 2016,including 79 males and 194 females,age between 46 to 87 years old,mean age(67.21± 8.23)years old. The clinical data were collected and the blood volume was calculated according to the Nadler formula. The Gross equation was used to calculate the blood loss and the amount of occult blood loss at 3 days after operation. The risk factors were analyzed statistically. Results The volume of hidden blood loss after operation was(75.36 ± 10.21)mL,and the volume of total blood lost after operation was(187.35± 60.31)mL.Sex,BMI and type of prosthesis were risk factors for hidden blood loss after UKA. Conclusions The volume of hidden blood loss after UKA was related to sex, BMI,and type of prosthesis. For the obese and male patients,we should actively take bleeding management and choose the type of prosthesis reasonably.
