Improving pain management after total knee surgery

Expanding the Peri-operative Surgical Home Model: ERAS TKR With a Transitional Pain Service (TeleTPS) - Continuous Adductor Canal Catheter Versus Adductor Canal Block for Total Knee Arthroplasty, a Randomized Double-blinded Controlled Trial.

Not applicable Interventional Hospital for Special Surgery, New York · NCT05981105

This study is testing whether a special pain management device can help people who have had knee surgery use less opioid medication and feel less pain as they recover.

What this trial studies

This clinical trial aims to evaluate the effectiveness of an adductor canal catheter (ACC) compared to a sham catheter in reducing opioid consumption and managing pain in patients undergoing total knee arthroplasty. Participants will be randomly assigned to receive either the ACC or a sham catheter and will use a mobile application to communicate with their pain management team. The study will track opioid use and pain levels for up to six months post-surgery, focusing on the potential benefits of extended analgesia and early rehabilitation. The goal is to determine if continuous analgesia can reduce rebound pain and improve recovery outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with osteoarthritis scheduled for total knee arthroplasty who can follow the study protocol and live within one hour of the hospital.

Not a fit: Patients with chronic opioid use, severe comorbidities, or those undergoing general anesthesia may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce opioid use and improve pain management for patients after knee surgery.

How similar studies have performed: Other studies have shown promise in using regional anesthesia techniques to improve pain management and reduce opioid consumption, making this approach both relevant and potentially impactful.
