Ultrasound-guided Continuous Proximal Adductor Canal vs Continuous Femoral Nerve Block for Postoperative Pain Control and Rehabilitation Following Total Knee Arthroplasty

Yale University

Overview

The purpose of the study is to compare continuous femoral nerve block with continuous proximal adductor canal block for postoperative pain control and rehabilitation.

Patients meeting the criteria: American Society of Anesthesiologists (ASA) class I and II, that are scheduled for elective total knee arthroplasty, will be recruited into the study. Subjects will be randomized into 2 groups: those who will receive a continuous proximal adductor canal block (ACB) and those who will receive a continuous femoral nerve block (FNB).

Outcomes

Primary Outcomes

Motor effects

Subjects' change in motor effects will be assessed as maximum voluntary isometric contraction (MVIC) in the quadriceps muscle.

Time frame: 24 hours (postoperatively)

Secondary Outcomes

Pain score

Subjects' pain will be assessed using a numerical pain score, where 10 is the greatest amount of pain.

Time frame: On average between 6 and 8 hours postoperatively

Pain score

Time frame: 24 hours (postoperatively)

Opioid consumption

Subjects' pain will be assessed by tracking opioid consumption postoperatively.

Time frame: On average between 6 and 8 hours postoperatively
