It was reported that during removal of a right proximal tibial plate approximately twenty-two months post-implantation, it was found that some of the screws were stripped and some of the locking screws were cold welded to the plate.Ultimately, the plate and one screw were left implanted in the patient, as they were unable to complete the removal.
