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

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

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).

Inclusion Criteria:

• Patients with an American Society of Anesthesiologists Physical Status Classification System (ASA) score of 1 or 2 that are healthy without systemic disease or have mild systemic disease, respectively.
• The patient will need to be able to have decision-making capacity and ability to consent for the study.

Exclusion Criteria:

• Patients with an American Society of Anesthesiologists Physical Status Classification System (ASA) score greater than 2.
• Patients unable to have decision-making capacity and ability to consent for the study.
