Ropivacaine 0.5%
The volume of local anesthetic Ropivacaine 0.5% will be determined by the response (success or failure of block, 30 minutes after local anesthetic injection) of the previous patient in that group. Block success is defined as an absence of ice sensation in the knee within 30 min of ropivacaine administration accompanied by tolerance to tetanic electrical stimulation (TES) at 60 mA(milliamp) for 5 seconds.
