The complaint device was received and evaluated.There were no anomalies to the returned anchor that would have contributed in the reported pull out failure.Visual observation of the inserter revealed that the distal end is bent, which is a high possibility that this damage would have caused the anchor to fail and not get implanted correctly.This failure of the inserter is attributed to hitting a hard surface or applying excessive bending force while implanting the anchor, indicating mishandling of the device.Other than this possibility, a root cause is undetermined at this point.A batch record review has been conducted and our results indicate that this batch of product was processed without incident and therefore there is no internally assignable cause for the reported problem.Further, a review into the depuy synthes mitek complaints system revealed no other complaints of any type for this lot of devices that were released to distribution.At this point in time, no corrective action is required and no further action is warranted.However, depuy synthes mitek will continue to track any related complaints within this device family as a means of monitoring the extent with which this complaint is observed in the field.
