First received: October 5, 2009
Last updated: January 11, 2011
Last verified: October 2009
The purpose of this study is to determine if the agent, Floseal, can decrease the amount of blood patients lose after total knee replacement (TKR) surgery. If this product can be found to have an effect on bleeding, it may potentially reduce the problems associated with bleeding after knee replacement surgery such as pain, stiffness, and the need to have a blood transfusion. The subject's overall participation will be over a period of 6 weeks.

Primary Outcome Measures:
  • Fall in post-operative hemoglobin and hematocrit. Data will be collected from laboratory tests [ Time Frame: before surgery and the first and second days after surgery ]
  • Drain output in milliliters at 24 hours. This will be recorded from the time the drain was inserted. [ Time Frame: 24 hours ]
  • Transfusion requirements - The total number of units, along with the individual number of autologous and homologous units required for each patient will be recorded. [ Time Frame: The three days following surgery ]

Secondary Outcome Measures:
  • Range of Motion [ Time Frame: 3 days after surgery, 6 weeks after surgery ]
  • Pain scores [ Time Frame: 3 days after surgery, 6 weeks after surgery ]
