Design outcomes

Primary

MeasureTime frame
We expect that blood loss, based on postoperative hemoglobin levels in relation to preoperative levels adjusted for blood volume, will be lower in the group of patients in the tourniquet group optimized compared to the group without use of the tourniquet—

Secondary

MeasureTime frame
We expect the need for blood transfusion, surgical time, pain level, edema, movement gain to be lower in the group with the use of an optimized tourniquet;We expect better quadriceps function through objective analysis with isokinetic dynamometer and lesser degree of muscle impairment estimated through CPK measurement serum in the group with use of the tourniquet optimized in relation to the group without its use.;Esperamos escores funcionais HSS superiores no grupo com torniquete otimizado do que no grupo sem seu uso.—
