What this trial studies

This study evaluates the effectiveness and safety of a continuous adductor canal block (CACB) in patients undergoing fast track total knee arthroplasty (TKA). The approach involves the use of a perineural catheter to deliver local anesthetic, aiming to enhance pain management and reduce opioid consumption post-surgery. The study will measure patient-reported quality of recovery and assess the rate of readmissions. Investigators hypothesize that CACB will lead to improved outcomes compared to traditional pain management methods.

Who should consider this trial

Good fit: Ideal candidates are adults over 21 undergoing unilateral primary TKA in a fast track setting with no history of drug dependency.

Not a fit: Patients with chronic opioid use, coagulopathy, or contraindications to catheter placement may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce opioid use and improve recovery quality for patients undergoing knee surgery.

How similar studies have performed: While there are no published prospective randomized controlled trials specifically assessing CACB in same-day primary knee arthroplasties, the approach shows promise based on existing literature.
