Manufacturer Narrative

An event regarding a seating/locking issue involving a triathlon insert was reported.The event was not confirmed.Conclusion: the exact cause of the event could not be determined as insufficient information was provided.Further information such as pre- and post-operative x-rays and the primary operative report as well as patient history and follow-up notes are needed to complete the investigation for determining root cause.A trend analysis was conducted for the reported failure mode and concluded that seating/locking difficulties may arise from user-related issues associated with the preparation of the joint space prior to the attempted seating and with the technique required to correctly introduce the insert component to the baseplate.No further investigation for this event is required at this time.
