Manufacturer Narrative

Complaint reference number: (b)(4).

Event Description

It was reported that, after right partial knee replacement surgery had been performed on (b)(6) 2022, the patient experienced pain on the right knee.This adverse event was solved by revision surgery performed on (b)(6) 2023, in which all four (4) components were revised, and zimmer persona competitor devices were implanted.The engage tibial insert sz 6-rt med 10mm had visible wear and the engage porous tibial tray sz 6-lt med and engage porous femoral sz 6-rt med had bone ingrowth.Current health status of patient is unknown.

Manufacturer Narrative

H3, h6: the associated devices were returned and evaluated.The visual inspection did not reveal the stated failure mode.A lab analysis performed on the devices revealed that the articulating surfaces have light scratching.The mating surfaces between the tibial insert and tibial baseplate have marring.The tibial insert contains damage to the locking detail.The tibial anchor stem consisted of wear, missing one locking detail and damage to the other, and surface discoloration.The bone contacting surfaces of the tibial and femoral components contain a substance that is adhered.There were no observations of material or manufacturing deviations in the course of this investigation.The clinical/medical investigation concluded that, based on the limited information provided, definitive clinical factors which may contributed to the patient¿s pain cannot be concluded.The reported insert wear was not visually confirmed per product evaluation; however, due to signaling, a field action was generated and a recall decision was made in order to mitigate future recurrence.The patient impact included the reported pain and insert wear with revision/conversion to competitor tka.Further patient impact cannot be determined.No further medical assessment can be rendered at this time.A review of the production records did not reveal a manufacturing abnormality that could have caused or contributed to the reported incident.A review of complaint history based on the historical data revealed similar previous events, however, no commonalities that would suggest a device deficiency were found.A review of the instructions for use documents for engage partial knee system revealed in the warnings and precautions section that the success of the operation depends on compliance with the operative technique supplied, and the proper use of the instrumentation supplied and specially designed for that range of implants.Additionally, incorrect fixation or positioning of the components, pain and excessive wear of the polyethylene component have been identified in the adverse effects and complications.Deformation or wear from one or more of the prosthetic components is often related to the risk factors detailed in the document.There is not enough data available to conclude that the overall clinical benefit outweighs the potential risk profile when compared to the state of the art.The existing data identifies a potential signal that the performance is an outlier vs the state of the art with respect to the risk for revision.In addition, a historical review concluded that no previous escalated actions for this type of issue were identified.However, as a correction action a voluntary market removal will be performed for the engage cementless partial knee system due recent complaint data that indicates that the revision rate may be trending higher than corresponding similar devices in global joint replacement registries.At this time, we have no reason to suspect that the product failed to meet any specifications at the time of manufacture.Factors that could contribute to the reported event include traumatic injury, joint tightness or patient condition.Based on this investigation, the need for corrective action is not indicated.
