Total Knee Replacement With Tourniquet or Aquamantys

Comparison to Short-duration Tourniquet Total Knee Arthroplasty (TKA) With the Aquamantys® Bipolar Sealer and the Standard of Care in the Setting of Outpatient TKA: A Randomized, Double-blinded Study

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®). 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®).
