Additional information.
Additional Manufacturer Narrative
Additional information - d1, d2, d4 (part #, udi).Manufacturing site evaluation: the device was not returned to the manufacturer for physical evaluation.Additionally, no on-site evaluation of the unit was performed and no parts were returned for failure analysis.Therefore, the investigation was not able to confirm a device issue that could be associated with the reported event.The device history records (dhr) were not able to be reviewed as no lot number was made available.However, all device history records (dhr) are reviewed and released according to documented procedures and a device is not released if it does not meet requirements or is nonconforming.A definitive conclusion regarding the complaint incident cannot be reached without a physical examination of the complaint device.

Additional Manufacturer Narrative
Additional information: d section - material code updated, and other fields, as applicable f9 approximate age of device.Implants had been sent to a third party for evaluation.Investigation results were updated by the manufacturer.Investigation: the investigation report of exponent noticed no dimensional deviation of the pe inlay (sw965).Unfortunately the exponent- investigation report contains only the dimensional analysis of the pe- inlay (sw965) but no analysis of the two plates.The result of the exponent- analysis shows no deviation to the product specification.Because additionally now the batch numbers of the two plates were received, it was possible to check the device history records.Even here no hints were found for a nonconformity of the sw990k or the sw991k.A further investigation without the explants is not possible.Batch history review: the device quality and manufacturing history records have been checked for all leading device(s) lot numbers and the product found to be according to our specification valid at the time of production.There is one similar complaint against the same lot number for sw991k.According to manufacturer's reporting evaluation in accordance with 21 cfr part 803, section 803.3, this event is considered reportable for the following reason - adverse event (not later than 30 days).The assessment for the reportability of this adverse event was based on the patient harm, revision surgery.Explanation and rationale: unfortunately the exponent investigation report contains only the dimensional analysis of the pe- inlay, but no analysis of the two plates.The result of the exponent analysis shows no deviation to the product specification.Because now the batch numbers of the two plates were available, it was possible to check the device history records.Even here there were found no hints for a nonconformity of the two plates.Because there are no products, and only minor information available, a definitive root cause analysis is not possible.Following causes are possible: - wrong system configuration selected by the user - wrong implant size chosen by the user - end plate formed too strong by the user - design layout unsuitable - inadequate patient behaviour because the device history records are without any deviation, a material defect or manufacturing failure can be excluded.Conclusion/preventive measures: the root cause cannot be finally concluded.See explanation and rationale above.
