Brief Summary
The application of a tourniquet for 5 minutes and subsequent reperfusion before actual inflation of the tourniquet for total knee arthroplasty (ischemic preconditioning) decreases the level of local inflammation and therefore postoperative pain in response to reperfusion of the ischemic extremity.

Outcome Measures
Primary Outcomes (1)
Postoperative Pain at Rest and Exercise as Assessed by Visual Analogue Scale (VAS) Scores at 48h After Surgery
Visual Analogue Scale (VAS) are used to measure the intensity of pain. The total scale ranged from 0 (no pain) to 10 (excruciating pain). The average value at POD 48hours was reported for each arm/group.
48hrs after surgery
Secondary Outcomes (8)
Overall Epidural Volume
At 48hrs after surgery
Muscle Oxygenation Over Calf at 48h After Surgery
At 48 hrs after surgery
Levels of Interleukin 6 (IL6) in Drainage Fluid at 24hr Postoperatively
At 24 hours postoperatively
Periarticular Circumference of the Knee at 6h, 24h, and 48h
measured at 6 hours, 24 hours, and 48 hours
Hospital Length of Stay

Study Arms (2)
Ishcemic Preconditioning
ACTIVE COMPARATORIn the study group, the patients' operative limb will be preconditioned by inflating the tourniquet for 5 minutes, followed by deflation and a 5-minute reperfusion period. Subsequently, the tourniquet will be inflated for the entire length of the operation (before skin incision to after insertion of the final components).
Control
NO INTERVENTIONIn the control group, the tourniquet will be used for the entire length of the operation without a preconditioning phase.
Interventions
In the study group, the patients' operative limb will be preconditioned by inflating the tourniquet for 5 minutes, followed by deflation and a 5-minute reperfusion period. Subsequently, the tourniquet will be inflated for the entire length of the operation (before skin incision to after insertion of the final components). In the control group, the tourniquet will be used for the entire length of the operation without a preconditioning phase.
Eligibility Criteria
You may qualify if:
- All patients undergoing primary total knee arthroplasty
You may not qualify if:
- Patients who chronically use narcotics (\<1 month).
- Patients with contraindications (severe peripheral vascular disease, presence of femoral-popliteal bypass grafts, etc.) or no plan for tourniquet use as determined by the clinical care team.
- Patients who are on corticosteroids prior to their surgery
