Summary

Adductor canal catheters are being used to provide continuous postoperative analgesia after total knee arthroplasty surgery (TKA). There is much debate about where is the best position of continuous adductor canal block in patients undergoing TKA. Therefore, the investigators aim to compare the postoperative pain at three different level of continuous adductor canal block. Ninety six patients scheduled for total knee arthroplasty will be randomly divided into the three groups. In group 1, the adductor canal catheter is inserted at femoral triangle apex (the proximal end of the adductor canal). In group 2, the adductor canal catheter is inserted femur length/15\*2 cm above the location where the nerve block performed in group 1. In group 3, the adductor canal catheter is inserted femur length/15cm below the location where the nerve block performed in group 1.
