Does Intramedullary Reaming in Total Knee Arthroplasty Increase Postoperative Bleeding? A Propensity Score-Matched Cohort Study.

ABSTRACT:

Background

There is conflicting evidence about whether avoiding medullary canal reaming of the femur during total knee arthroplasty (TKA) reduces blood loss. This study aimed to test the hypothesis that total blood loss would decrease in TKA without medullary canal reaming.

Method

This propensity score-matched cohort study included 349 patients, of whom 220 underwent TKA using a femoral intramedullary rod, and 129 underwent TKA using a computer-assisted system without a femoral intramedullary alignment system. For the proximal tibia resection, an intramedullary alignment system was not used in any of the patients. These patients were matched using a one-to-one propensity score method. The primary outcome was perioperative blood loss, calculated from patient blood volume and
