Summary

The use of a pneumatic tourniquet with the purpose of maintaining an operative field free of blood is a common practice in orthopedic surgery. Its use is associated with local and systemic consequences related to hemodynamic and reperfusion ischemia phenomena. Although is known that its use is not an innocuous measure, there is still certain degree blurriness regarding the potential metabolic and functional consequences that may result in the involved limb. In this trial, the investigators are setting out to discriminate the effect of the pneumatic tourniquet on thigh muscle function (strength, tone and activation). The hypothesis is that the pneumatic tourniquet by itself causes a significant postoperative muscular dysfunction of the quadriceps and, thus, the main outcome will be the presence of postoperative quadriceps muscle dysfunction, defined as a fall greater than or equal to 10% of the maximal voluntary isometric contraction measured at 24 hours post surgery.
