Area of Science:

• Orthopedic Surgery
• Transfusion Medicine

Background:

• Postoperative shed autologous blood reinfusion is a long-standing practice in total knee arthroplasty (TKA).
• Its clinical effectiveness and impact on patient outcomes remain subjects of ongoing debate within the medical community.

Purpose of the Study:

• To evaluate the efficacy of postoperative shed autologous blood reinfusion in total knee arthroplasty (TKA).
• To compare allogeneic blood transfusion requirements, associated costs, and hospital stay duration between patients who did and did not undergo this procedure.

Main Methods:

• A multicenter retrospective study analyzed medical records of patients undergoing unilateral and bilateral TKA between 2015 and 2017.
• Patients were categorized into control and shed autologous blood reinfusion groups for comparative analysis.

Main Results:

• No significant difference was found in the need for allogeneic red blood cell infusions between the groups for both unilateral and bilateral TKA.
• The use of shed autologous blood reinfusion was associated with increased transfusion-related costs.
• A potential trend towards extended postoperative hospital stays was observed in the reinfusion group.

Conclusions:

• Postoperative shed autologous blood reinfusion does not appear to decrease the requirement for allogeneic blood transfusions in TKA patients.
• The procedure incurs additional expenses and may potentially lengthen hospital stays, suggesting a need for re-evaluation of its routine use.
