Product complaint # (b)(4).Investigation summary: according for information received, it was reported that attune femoral sizer will no longer accept stylus, so can't size femur accurately.It did not happen in surgery.The product was returned to depuy synthes for evaluation.The depuy synthes team conducted a visual inspection of the returned device.Visual analysis of the returned device revealed that the attune mes sizing/rot gde exhibits an overall worn condition consistent with constant usage for a long period of time.Also, stylus assy was missing.This condition may occur during the cleaning/sterilization process, particularly when the components are assembled or disassembled.As these procedures are often repeated, there is an increased risk of components going missing.However, without concrete evidence or further information, it is not possible to determine a root cause.A dimensional inspection was not performed since it was not applicable to the complaint condition.Although a proper assessment could not be performed since the reported subcomponent stylus assy was not returned for evaluation, the test was perform manually and the device functioned correctly.The overall complaint was not confirmed as the observed condition of the attune mes sizing/rot gde would have not contributed to the complained device issue.¿ based on the investigation findings, it has been determined that no corrective and/or preventative action is proposed.There is no indication that a design or manufacturing issue has caused the reported complaint condition.As part of depuy synthes quality process, all devices are manufactured, inspected, and released to approved specifications.Additional monitoring for any potential safety signals will be conducted through complaint trending and other post-market safety surveillance activities.Device history lot: the product investigation found no evidence suspecting an error in the manufacturing or material that would be a contributing factor in the reported allegation(s).A manufacturing records evaluation (mre) was not performed.Corrected: h3.
