摘要
Background Total knee arthroplasty （TKA） is an important therapy for the treatment of various late-stage knee diseases. However, it has been observed that patients have lower hemoglobin （HB） counts postoperatively, which are significantly inconsistent with the measured blood loss. Although the concept of hidden blood loss has been presented in 2000, very little clinical attention has been paid since then. In this study, we investigated the characteristics and influential factor of hidden blood loss after TKA in treating knee osteoarthritis.
