Associated medwatch-reports: 2916714-2020-00078 (400468255).2916714-2020-00089 (400468931).General information we received a complaint regarding enduro components.This is one of 12 cases regarding "problems with enduro components", "implant loosening" and "black debris".Consequences for the patient post-operative medical intervention was necessary: revision surgery.Investigation: no product at hand, therefore an investigation at the devices is not possible.Batch history review: due to the fact that no lot numbers were provided, a review of the device history records must remain incomplete.Conclusion and root cause: based on the information available it is not possible to determine a definitive root cause for the failure at that time.In this case it could be probable that the failure is partially patient related.Rationale: on the basis of the current information and without a product for investigation, a clear conclusion/root cause for the implant loosening can not be drawn.Corrective action: product safety case was created.
