Event Description

It was reported that tibia base was loose and femoral thereby femoral component was severely mechanically damaged.

Manufacturer Narrative

The associated journey uni tibial baseplate, journey uni insert and uni femoral component were returned and evaluated.A lab analysis conducted during this investigation noted that damage was observed on the articular surface of the femoral component and on the lock and superior surface of the tibial base.The damage was likely created by contact between the femoral and tibial baseplate components.Deformation/damage observed on the tibial insert may have been created by third-body particulate (bone, bone cement, etc.) and/or by articulation against the damaged area of the femoral component.No material or manufacturing deviations were discovered in this investigation.A dimensional inspection performed on the baseplate found all features inspected are within specification.However there is noticeable damage to the top of the rail and on the tray surface.Dimensional inspection of the insert cannot be performed as part appears to have been autoclaved.Our investigation including a review of complaint history for the listed part revealed no prior complaints for the listed failure mode with the same batch number.A review of the manufacturing records for the listed batch did not reveal any deviation from the standard manufacturing processes.A clinical analysis noted no clinical relevant documents were provided to conduct a thorough medical assessment.The reported cd with x-rays has not been provided.No medical assessment is warranted at this time.No further investigation is warranted for this complaint; however we will continue to monitor for future complaints and investigate as necessary.We consider this investigation closed.Should additional information be received, the complaint will be reopened.
