Total Knee Replacement With Tourniquet or Aquamantys

Purpose

The purpose of this study is to compare quadriceps muscle strength, pain, opioid consumption and patient function during the first three months after short-stay total knee replacement between patients treated with short-duration tourniquet knee replacement with the Aquamantys® bipolar sealer versus those treated with the standard of care (tourniquet used throughout the case and no Aquamantys®). By doing this study, investigators hope to learn if short duration tourniquet knee replacement with the Aquamantys® bipolar sealer is more effective than standard of care (tourniquet used throughout the case and no Aquamantys®).
