The purpose of this prospective randomized double-blind study is to determine if the novel technique of ultrasound guided peri-arterial injection of local anesthetic around the femoral artery decreases ischemic hypertension associated with prolonged lower extremity tourniquet time during total ankle arthroplasty (TAA) and foot fusion surgeries. Patients will be randomized 1:1 to receive either local anesthetic or saline, which will be injected superomedially to the femoral artery in an attempt to block sympathetic afferents and decrease tourniquet associated hypertension intraoperatively.
