Active Noise-Cancelling Headphones With Closed-Loop Communication During Arthroscopic ACL Reconstruction
Sponsor: Fatih Sultan Mehmet Training and Research Hospital
Summary
Operating room noise may interfere with communication, concentration, and surgical workflow. Active noise-cancelling (ANC) headphones can reduce background auditory distractions; however, their potential benefit during surgery may depend on maintaining effective communication among surgical team members. This prospective randomized controlled trial evaluates the effect of ANC headphones integrated with a closed-loop communication system on operative efficiency and intraoperative workflow during arthroscopic anterior cruciate ligament (ACL) reconstruction. Participants undergoing primary arthroscopic ACL reconstruction are randomized to either an ANC group or a control group. In the ANC group, the surgeon, first assistant, and scrub nurse use ANC headphones connected through a closed-loop communication system during surgery. The control group undergoes surgery under standard operating room conditions. The primary outcome is operative time from skin incision to skin closure. Secondary outcomes include command acknowledgment time, instrument handover time, and repeated verbal requests assessed using objective video-based workflow analysis.

Active Noise-Cancelling Headphones With Closed-Loop Communication
Active noise-cancelling headphones connected through a closed-loop communication system are used by the surgeon, first assistant, and scrub nurse throughout arthroscopic ACL reconstruction. The system is intended to reduce perceived background auditory distractions while maintaining continuous verbal communication among the core surgical team.
Standard Operating Room Communication
The surgical team performs arthroscopic ACL reconstruction under routine operating room conditions and communicates using standard verbal communication without active noise-cancelling headphones or a dedicated closed-loop communication system.
