[Progress on recessive blood loss after total knee arthroplasty]

After total knee arthroplasty, the hemoglobin descending level is not in accord with blood loss volume because of recessive blood loss. Recessive blood loss will delay wound healing, increase infected opportunity, prolong rehabilitation exercise time, effect clinical outcome, so prevention of recessive blood loss is very important. This review is about the effect of gender, age, height and weight, tourniquet, operative time and operative trauma, postoperative anticoagulation, unilateral or bilateral total knee arthroplasty, autoblood reinfusion on the recessive blood loss, which maybe is helpful for the prevention of recessive blood in total knee arthroplasty.
