Intervention

Procedure:
• ultrasound guided long axis placement of adductor canal catheter
The long axis of the ultrasound probe is placed parallel to the long axis of the adductor canal while scanning, and the catheter is placed along the long axis of the canal using an in-plane approach
• ultrasound guided short axis placement of adductor canal catheter
The long axis of the ultrasound probe is placed vertical to the long axis of the adductor canal while scanning, and the catheter is placed along the short axis of the canal using an in-plane approach

Device:
• Philip CX 50 Ultrasound Scanner
The linear (C5-12) probe of Philip CX 50 Ultrasound Scanner is used for scanning
• PAJUNK Contiplex S Catheter

Drug:
• Ropivocaine
0.2% ropivacaine 10ml is given as loading dose. Following that, 0.2% ropivacaine 5ml/h is given as maintenance dose.
• rescue sulfentanil given postoperatively as PICA
bolus: 2mg, lock time: 10min, 1h limitation: 8mg
