Batch review performed on 28 april 2022.Lot 2103557: (b)(4) items manufactured and released on 27-may-2021.Expiration date: 2026-05-11.No anomalies found related to the problem.To date, (b)(4) items of the same lot have been sold without any similar reported event.Clinical evaluation performed by medical affairs director.Few weeks after primary unicompartmental arthroplasty a fracture occurs and the surgeon decides to convert to a total knee.The radiographs attached are of very low quality and no evaluation is possible.There is no mention of a traumatic event.The bone fracture must have been caused either by a trauma or by the inevitable weakening of the bone consequent to the surgical procedure.In either case, we see no reason to suspect that a defective device is at the root of this adverse event.
