Active Noise-Cancelling Headphones With Closed-Loop Communication During Arthroscopic ACL Reconstruction (ANC-ACL-2026)
Effect of Active Noise-Cancelling Headphones With Closed-Loop Communication on Operative Efficiency During Arthroscopic Anterior Cruciate Ligament Reconstruction: A Randomized Controlled Trial

Yksityiskohtainen kuvaus
Operating room noise represents a potential source of distraction and may interfere with effective communication, concentration, coordination, and surgical workflow. Active noise-cancelling headphones can reduce perceived background auditory stimuli; however, conventional noise-cancelling devices may also interfere with communication when used without a dedicated communication system.
This prospective, single-center, randomized controlled trial evaluates whether active noise-cancelling headphones integrated with a closed-loop communication system improve operative efficiency and intraoperative workflow during arthroscopic anterior cruciate ligament reconstruction.
Patients undergoing primary arthroscopic ACL reconstruction for isolated ACL rupture are randomized in a 1:1 ratio to an intervention group or a control group.
In the intervention group, the surgeon, first assistant, and scrub nurse use active noise-cancelling headphones connected through a closed-loop communication system throughout the surgical procedure. This system is designed to reduce perceived background auditory distractions while maintaining continuous verbal communication among the core surgical team. The anesthesia team does not use headphones and maintains awareness of monitor alarms, ventilator alarms, and operating room announcements. When required, communication between the anesthesia and surgical teams occurs using standard verbal communication.
In the control group, arthroscopic ACL reconstruction is performed under standard operating room conditions without active noise-cancelling headphones or an additional closed-loop communication system.
All procedures are performed using a standardized single-bundle hamstring autograft ACL reconstruction technique, standardized instrumentation, fixation systems, arthroscopic equipment, and operating room setup.
The primary objective is to evaluate the effect of ANC-assisted closed-loop communication on operative time. Secondary objectives include assessment of objective communication and workflow parameters, including command acknowledgment time, instrument handover time, and repeated verbal requests.
