No difference in blood loss between posterior-cruciate-ligament-retaining and posterior-cruciate-ligament-stabilized total knee arthroplasties

This report has been verified by one or more authors of the original publication.

100 patients diagnosed with unilateral primary knee osteoarthritis were randomized to receive a posterior-cruciate-ligament-retaining (PCR) or a posterior-cruciate-ligament stabilized (PS) approach to primary cemented total knee arthroplasty. Blood loss and blood transfusion volumes were compared between treatment groups. Results revealed the PS approach did not influence the amount of postoperative blood loss or need for blood transfusions in the 5 day postoperative period when compared to the PCR technique.
