Additional Manufacturer Narrative
Product complaint #(b)(4).Investigation summary = > spring ring detached from trial intro-op.It was reported that the patient had a knee surgery on (b)(6) 2024.Today, the patient had a post-operative film, and was found a foreign matter in the knee joint.After checked, the foreign matter is the spring ring of the trial.The patient recovered well currently, no plan to remove the spring ring so far.The product was returned to depuy synthes for evaluation.Visual analysis revealed that the spring present around one of the post was deformed.Additionally, the spring is missing.The x-ray investigation revealed an unknown object remains in patient , however with the provided information is not possible determinate if the unknow object is part of the attune fb ps artic surf sz4.No other issues were observed.The failure mode is consistent with inserting an extractor device in between the trial and mating shim, and using the extractor to pry the mating devices apart during extraction of the trials.This improper technique results in damage to the spring and/or post components of the articulating surface as well as the mating shim.The attune intuition surgical technique 0612-10-512 (page 53), emphasizes the correct use of the tibial trial extractor (product code 254500138) with the trials.Furthermore, on page 51 of the surgical technique and per ifu-0902-00-836, careful inspection of the trials for damage/breakage should be performed pre and post-operative.If any damage to the balseal components is observed the trail should be replaced.In the event of instrument breakage during use, ensure that all device fragments that may have entered the surgical site are removed prior to completion of the procedure, as patient injury may result.The overall complaint was confirmed as the observed condition of the attune fb ps artic surf sz4 would contribute to the complained device issue.Based on the investigation findings, the potential cause is traced to unintended user error, and 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 complaint condition.Additional monitoring for any potential safety signals will be conducted through complaint trending and other post-market safety surveillance activities.As part of depuy synthes quality process, all devices are manufactured, inspected, and released to approved specifications.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.H11 additional narrative: corrected: h3.
