Comparing two methods of pain relief after knee surgery

Continuous Distal Adductor Canal Block With Periarticular Local Anesthetic Infiltration Versus Continuous Distal Adductor Canal Block Alone for Analgesia After Total Knee Arthroplasty

Not applicable Interventional Yonsei University · NCT05427019

This study is testing if adding a local anesthetic injection to a nerve block can help people feel less pain after knee surgery compared to just using the nerve block alone.

What this trial studies

This study investigates the effectiveness of continuous distal adductor canal block combined with periarticular local anesthetic infiltration versus the distal adductor canal block alone for managing postoperative pain in patients undergoing total knee arthroplasty. Sixty-six patients will be randomly assigned to receive either the combined treatment or the single treatment. The aim is to determine if the addition of periarticular infiltration enhances pain relief compared to the adductor canal block alone. The study focuses on the analgesic effects on posterior knee pain, which is a common issue after knee surgery.

Who should consider this trial

Good fit: Ideal candidates are adults aged 19 and older scheduled for elective unilateral total knee arthroplasty with an ASA physical status of 1-3.

Not a fit: Patients with allergies to study drugs, hepatic or renal insufficiency, opioid dependency, coagulopathy, pre-existing neurologic deficits, or severe psychiatric illness may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve pain management for patients recovering from total knee arthroplasty.

How similar studies have performed: Previous studies have shown promising results with similar analgesic techniques, suggesting potential for success in this approach.
