Summary
This study was designed to test a device called RELAY that delivers both local anesthetic and electrical nerve stimulation through a single catheter after knee surgery. The goal was to provide up to 28 days of pain control, longer than current options. However, the study was withdrawn before any participants were enrolled, so no data was collected.
