The Appropriate Level of Continuous Adductor Canal Block in Patients Undergoing Total Knee Arthroplasty (TKA)

Not Applicable

Completed

• Conditions: Degenerative Arthritis

• Registration Number: NCT04206150
• Lead Sponsor: Yonsei University

Brief 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.

Primary Outcome Measures

Name	Time	Method
Pain : Visual Analogue Scale (VAS) for pain	postoperative day 2	The visual analog scale(VAS) is a validated, subjective measure for acute and chronic pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between "no pain" (0) and "worst pain." (10). The ends are defined as the extreme limits of the parameter to be measured(symptom,pain,health) orientated from the left(0, worst) to the right(10, best).

Secondary Outcome Measures

Name	Time	Method
muscle strength	postoperative day 2	Quadriceps strength of both legs was assessed by placing the dynamometer on the anterior of the ankle, between the malleoli.
