This study aims to evaluate the effect of postoperative blood recovery with reinfusion drains on hematologic parameters and blood transfusion rate in patients undergoing total joint arthroplasty. Three-hundred-and-forty-four patient records were reviewed and 271 patients were included in the study; 56.8% of patients were treated with postoperative cell salvage procedure using reinfusion drains (PCS) and 43.2% had closed-suction drain (CSD) postoperatively. In comparison to the CSD group, the PCS group showed higher hemoglobin (Hb) levels on the first and second days postoperatively but no statistical differences were noted at the day of discharge. 75.2% and 37.7% of patients required blood transfusions in the CSD and PCS groups, respectively. The PCS group had a lower number of blood transfusions than the CSD group. At multivariate analysis, Hb loss rate was related to preoperative Hb values, total amount of drained blood and chronic antiplatelet therapy. The number of blood transfusions was related to preoperative Hb values, closed-suction drains, preoperative platelet count, TKA surgery and BMI. This study supports the use of PCS with reinfusion drains after THA and TKA at least for the short-term.
