Participant Flow

Patients were recruited from the medical clinics of Weiler and Montefiore hospitals under the Montefiore system in the Bronx, NY. Patients undergoing a total knee arthroplasty (TKA) were recruited over a 10 month period and either received hemostasis with the standard unipolar cauterizing device or the bipolar saline system.

Patients who were on anticoagulation therapy prior to their TKA were excluded from our study as this potentially would increase their amount of post-operative bleeding complicating the results of our study.
