Comparing two types of nerve blocks for pain management after knee surgery

Official title: The Impact of Single-shot Adductor Canal Block Versus Continuous Femoral Nerve Block on Rehabilitation After Total Knee Replacement (AdORe - ACB)

Run by Negovsky Reanimatology Research Institute · NCT05487053 · Data updated 2026-11-12

This study is testing whether a single injection of a nerve block can help control pain after knee surgery better than a continuous nerve block, while also allowing for easier movement and recovery.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older who are scheduled for primary total knee replacement and can provide informed consent.

Probably not a fit

Patients requiring urgent surgery, those with specific contraindications, or those who have previously participated in this trial may not benefit from this study.

What this trial studies

This study compares the effectiveness of a single-shot adductor canal block (ACB) versus a continuous femoral nerve block (FNB) for managing postoperative pain in patients undergoing total knee replacement. The goal is to determine which method provides better pain relief while minimizing motor impairment and enhancing recovery. ACB is hypothesized to offer similar analgesia without affecting the quadriceps muscle function, potentially leading to improved rehabilitation outcomes. Participants will be monitored for pain levels, functional recovery, and any complications related to the nerve blocks.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies that enhance recovery and reduce complications after total knee replacement.

How similar studies have gone: Previous studies have shown promising results with adductor canal blocks, suggesting they may be a viable alternative to femoral nerve blocks, but this specific comparison is less commonly tested.
