Historically, patients undergoing an elective hip, knee or shoulder arthroplasty regularly required blood transfusions. Improved surgical techniques and perioperative optimisation have significantly decreased the requirement for blood transfusions. Currently, our patients have two group and save samples taken: one six weeks preoperatively and one on admission. This study aims to determine whether a second group and save is required prior to primary elective hip, knee or shoulder arthroplasty.

Are on-the-day group and save samples required for elective shoulder, hip and knee arthroplasties?
