Study to Compare the Addition of Floseal to Our Standard of Care to Control Post Operative Bleeding in TKR

Floseal (5 milliliters) will be applied to the exposed bone in the following order: around the margins of the tibia, the femur (anterior surface, intercondylar notch, exposed medial and lateral condyles) and around the un resurfaced portion of the patella. The other syringes (each of 5 milliliters) will then be applied to the supra-patellar synovium and into the medial and lateral gutters of the knee. No Floseal will be applied outside the knee joint capsule.
