Event Description

It was reported that during surgery, right after removing the original insert, the surgeon implanted a patella and thoroughly cleaned and cleared the tibial base plate and surrounding tissue to insert the replacement poly.After 3 failed attempts to lock down the poly a second back up poly was opened and impacted down correctly on the first attempt.It is unknown if there was any delay nor injury reported.

Manufacturer Narrative
|
H3, h6: the device, used in treatment, was returned for evaluation.A visual inspection of the returned device shows damage on the lock detail probably from the attempted insertion.A review of the complaint history on the listed part revealed no prior complaints for the listed failure mode with the same batch number.A review of the manufacturing or product specifications for batch did not reveal abnormalities that could have contributed to the reported issue.A review of the risk management file and instructions for use document for this failure mode was conducted and concluded this failure mode has been identified.Our clinical/medical team noted: this complaint reports that during a revision the poly insert would not lock down after 3 attempts, so a backup device was used to complete the procedure.Per email communication, the requested x-rays and surgical reports will not be provided due to no consent being given.Therefore, no further medical assessment can be performed at this time.Should clinically relevant documentation/ information become available, the clinical/medical task may be re-evaluated.Some potential probable causes for this event could include a fit/ sizing issue or poor insertion technique.Based on this investigation, the need for corrective action is not indicated.Should additional information be received, the complaint will be reopened.No further investigation warranted for this complaint, however we will continue to monitor for future complaints and investigate as necessary.We consider this investigation closed.
