This report is being submitted in pursuant to the provisions of 21 cfr, part 803.This report may be based on information which has not been able to investigate or verify prior to the required reporting date.This report does not reflect a conclusion by depuy mitek or its employees that the report constitutes an admission that the device, depuy mitek, or its employees caused or contributed to the potential event described in this report.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.Device was used for treatment, not diagnosis.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.Udi: (b)(4).Investigation summary: both photos and the complaint device were received and evaluated.Photos were returned to depuy synthes mitek for evaluation.The depuy synthes mitek team conducted a visual inspection of the returned photos.Upon visual inspection of the photos, the anchor was not attached and the tip was deformed.It was not possible to see the condition of the anchor.The product was returned to mitek for evaluation.Mitek then conducted visual inspection of device received.Upon visual inspection, the anchor was not received along with the device.The tip was deformed and the suture was not in the shaft.As part of depuy synthes mitek quality process all devices are manufactured, inspected, and released to approved specifications.A manufacturing record evaluation was performed for the finished device lot number: 116l561, and no non-conformances were identified.As part of depuy synthes mitek quality process all devices are manufactured, inspected, and released to approved specifications.According of the findings, this complaint cannot be confirmed, and a root cause of the issue reported cannot be determined.The condition of the inserter could be related to handling of the device.No further information regarding the cause of the defect has been provided to help determine a root cause for this failure.If the component (polylactic acid (pla) of this device is exposed to high temperatures, its structure gets compromised as it tents to lose mass, it provides flexibility to the polymer chains producing a decrease in the degree of crystallinity of the structure and the microhardness values causing these types of deformations.These conditions have typical characteristics of material exposed to temperatures higher, however this cannot be conclusively determined.The possible root cause of the issue reported is that the devices were exposed to an elevated temperature before it was opened in the operating room prior to surgery.The elevated temperature and the slight tension on the suture could result bending the anchor.Per further analysis, the risk level for visual: deformed/bent is an acceptable risk (ar) within risk management documents.Per ifu- 108805, ¿storage¿ section to store in a ¿cool and dry¿ place.At this point in time, no corrective action is required, and no further action is warranted.However, in depuy synthes mitek, additional complaint information monitoring for potential safety signals is conducted through complaint trending as part of post market surveillance.
