Is this trial a fit for you?

Likely a good fit

Adults 19–55 years old scheduled for elective ambulatory knee arthroscopy lasting ≤80 minutes, ASA I–II, no prior opioid or psychotropic use, able to consent and complete questionnaires.

Probably not a fit

Patients with longer or more complex surgeries, prior opioid use, psychiatric conditions, or inability to comply may not experience benefit and could have less favorable outcomes.

What this trial studies

In this prospective, non-randomized pilot, 60 adults undergoing ambulatory knee arthroscopy under general anesthesia are assigned to receive either standard pain treatment plus acupuncture or standard pain treatment alone. The acupuncture group uses indwelling fixed needles as part of the post-surgical care plan, with outcomes including analgesic use, pain scores, side effects, physiological measures, and mobilization. The trial focuses on short-term postoperative pain management and early mobilization. Inclusion is limited to adults aged 19–55 without prior opioid or psychotropic use, and surgery time must be 80 minutes or less. The study aims to inform whether acupuncture could improve recovery after AKS in a real-world, non-randomized setting.

Why it matters

Potential benefit: If successful, patients could experience less pain and lower need for analgesics after knee arthroscopy.

How similar studies have gone: Previous research on acupuncture for postoperative pain has shown mixed or modest benefits in similar settings; this study adds data from a non-randomized pilot.
