At the conclusion of the case, each patient will receive a dry sterile dressing, followed by a compression wrap and a hinged knee brace locked in extension. No drains, pain pumps or nerve stimulators will be used. The nurses in the recovery room who will be administering the VAS assessment and recording time and frequency of pain medication dosing will be blinded to the patients' Group number. The nurses will provide pain medications and the visual analog assessment for their duties in the post-op anesthesia unit, and are not administering drugs or procedures specifically for research purposes.
