On 11th dec 2025, it was reported by an arthrex's employee via an email that for 1 unit of ar-8400td, torpedo, 4.0 mm x 13 cm, an abnormal noise was detected when the inner core was rotating.When the inner core was pulled out, it was found to be deformed.This was detected during a knee joint debridement surgery on (b)(6) 2025.The procedure was completed successfully by using another new ar-8400td.There were no patient harm and no secondary procedure needed.
