Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study compares the long-axis and short-axis technique of continues adductor canal block for total knee replacement surgery. Half participants will receive long-axis catheterization, while the other half will receive short-axis catheterization.

short axis (SAX) placement of adductor canal catheters

Procedure: Ultrasound guided short axis (SAX) placement of adductor canal catheters Philip CX50 ultrasound scanner guided insertion of a PAJUNK Contiplex S catheter along the short axis of the middle part of adductor canal

Group Type ACTIVE_COMPARATOR

ultrasound guided short axis placement of adductor canal catheter

Intervention Type PROCEDURE

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

Philip CX 50 Ultrasound Scanner

Intervention Type DEVICE

The linear (C5-12) probe of Philip CX 50 Ultrasound Scanner is used for scanning

PAJUNK Contiplex S Catheter

Intervention Type DEVICE

Ropivocaine

Intervention Type DRUG

0.2% ropivacaine 10ml is given as loading dose. Following that, 0.2% ropivacaine 5ml/h is given as maintenance dose.
