A Cohort Study With 100 Subjects Having a Primary Total Knee Replacement, Taking Pradax Post Discharge for Ten Days
A Cohort (Follow Up) Study With 100 Subjects Having a Primary Total Knee Replacement, Taking Pradax (Tablet) Post Discharge for Ten Days, Without the Need for Routine Coagulation Monitoring and Dose Adjustment
Currently standard of care for preventing blood clots in total knee replacement patients is the drug Fragmin which is a daily injection for 10 days after surgery. Patients are in hospital for 3 to 5 days after total knee replacement surgery and patients are taught in hospital to do their injections.
The investigators would like to introduce the drug Pradax. Pradax is a Health Canada approved once a day, oral drug that may prevent blood clots in the patient's leg. In this study the patient will receive the standard of care injection drug Fragmin while in hospital but on discharge home the patient will take the oral drug Pradax daily (2 tablets 110mg) for 10 days.

Experimental: Pradax
This is the only arm in the study and all will follow the same protocol for the study which is taking the pradax after total knee replacement
|
Pradax (dabigatran etexilate) is a prodrug that when converted to the active from in the liver and plasma it becomes a reversible, competitive direct thrombin inhibitor.
Thrombin catalyses the conversion of soluble fibrinogen into soluble fibrin, the final step in the coagulation cascade.
Pradax competitively blocks the active site of both free and clot-bound thrombin, preventing the development of a thrombus.
they will take 110 mg 1-4 hours post op. and 220mg daily until 10 days post op.
