Measure
Ropivacaine 0.75% Injectable Solution
The patients receive 10 ml of intraarticular solution in the knee (at the anatomical point at the level of the upper pole of the ball joint, under the iliotibial band), with different content of ropivacaine 0.75%; the vehicle for application presents the same physical appearance for all patients and is applied by previously standardized treating physicians. Ropivacaine 0.75% Injectable Solution: The patients receive 10 ml of intraarticular solution in the knee (at the anatomical point at the level of the upper pole of the ball joint, under the iliotibial band), with different content of ropivacaine 0.75%; the vehicle for application presents the same physical appearance for all patients and is applied by previously standardized treating physicians.
Ropivacaine 0.2% Injectable Solution
The patients receive 10 ml of intraarticular solution in the knee (at the anatomical point at the level of the upper pole of the ball joint, under the iliotibial band), with different content of ropivacaine 0.2%; the vehicle for application presents the same physical appearance for all patients and is applied by previously standardized treating physicians. Ropivacaine 0.2% Injectable Solution: The patients receive 10 ml of intraarticular solution in the knee (at the anatomical point at the level of the upper pole of the ball joint, under the iliotibial band), with different content of ropivacaine 0.2%; the vehicle for application presents the same physical appearance for all patients and is applied by previously standardized treating physicians.
