  Purpose
The use of Aquamantys during total knee arthroplasty will reduce drain output and the necessity for blood transfusions.

Primary Outcome Measures:
  • Drain Output. [ Time Frame: First 24 hours following surgery. ]
    This is a measure of the average drain output collected in the first 24 hours following surgery.


Secondary Outcome Measures:
  • Change in Hemoglobin and Hematocrit. [ Time Frame: First three days after surgery. ]

Enrollment: 111
Study Start Date: August 2009
Study Completion Date: April 2010
Primary Completion Date: April 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: TKA with the Aquamantys for hemostasis
This arm will receive the total knee arthroplasty with the Aquamantys device used for hemostasis.
Device: Aquamantys Device
The Aquamantys is used for hemostasis in patients randomized to receive total knee arthroplasty with the device.
Active Comparator: TKA without the Aquamantys for hemostasis
This group will receive total knee arthroplasty using the standard treatment for hemostasis.
Other: Standard of care treatment for hemostasis during a total knee arthroplasty.
The active comparator arm will receive the "standard-of-care" for hemostasis during total knee arthroplasty. This is achieved with a unipolar Bovie electrocauterization device.
