Tourniquets have been used for many years during total knee arthroplasty as a means of achieving a bloodless field for better visualization and cement-bond inter-digitation. Controversy has surrounded the necessity for a tourniquet in past years. There are many advantages and disadvantages to using a tourniquet, and one prominent disadvantage is a purported increase in post-operative pain and limitations in range of motion.

Secondary outcomes included were functional in nature, namely range of motion and post-operative hospital stay.Introduction
