Is this trial a fit for you?

Likely a good fit

Adults 18-65 years undergoing meniscopathy/arthroscopic knee surgery with ASA I-III and BMI 18-30.

Probably not a fit

Patients with ASA IV or higher, BMI outside 18-30, or those with bleeding disorders may not benefit or may be excluded due to safety risks.

What this trial studies

This interventional study compares three analgesic approaches after meniscopathy surgery: adductor canal block (ACB) alone, ACB combined with a BiFeS block, and a control group. The aim is to determine if the BiFeS block adds pain relief while preserving motor function. Participants are adults aged 18-65 with ASA I-III and BMI 18-30, undergoing arthroscopic knee procedures. Analgesic efficacy and safety will be assessed to inform multimodal pain strategies for postoperative recovery.

Why it matters

Potential benefit: If successful, the BiFeS block added to ACB could provide stronger pain control and facilitate earlier mobilization after knee arthroscopy.

How similar studies have gone: Previous regional blocks show that multimodal approaches can improve analgesia, but the specific BiFeS addition is a newer approach with limited long-term outcome data.
