What this trial studies

This study investigates the effectiveness of a continuous infusion combined with intermittent bolus of local anesthetics for adductor canal block in patients undergoing total knee arthroplasty. The goal is to assess whether this method can provide better pain relief and reduce opioid consumption compared to traditional longer interval bolus techniques. By targeting specific nerve branches responsible for pain during recovery, the study aims to enhance patient outcomes and facilitate rehabilitation. Participants will receive bupivacaine as part of their pain management protocol.

Who should consider this trial

Good fit: Ideal candidates are adults undergoing unilateral total knee arthroplasty under spinal anesthesia with an ASA classification of 1-3.

Not a fit: Patients with chronic pain, long-term opioid use, or neuromuscular diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve pain management and recovery for patients undergoing knee replacement surgery.

How similar studies have performed: Previous studies have shown promising results with adductor canal blocks, suggesting that this approach may be effective, though this specific method is being tested for the first time.
