Results of investigation: it was reported that during tka surgery, the journey uni tibial insert s5-6lm/rl8mm could not be implanted.The surgeon made a change in surgical technique and used a bigger size insert to complete the procedure.The affected complaint device, used in treatment, was returned and evaluated.A visual inspection of the returned device shows damage on the lock detail probably from the attempt of insertion.Dimensional analysis could not be performed as the damage/deformation at several features of the device would not allow for accurate measurement.There is no information that would suggest the device failed to meet specifications.A relationship, if any, between the device and the reported incident could not be corroborated.Based on this investigation, the need for corrective action is not indicated.A clinical analysis noted all documents and images provided as of this date have been reviewed and consider and unless noted do not contribute to the clinical investigation.A review of risk management files found that the reported failure was documented appropriately.The instructions for use indicated in the warnings and precautions that it is extremely important to select the appropriate type and size with consideration of anatomical and biomechanical factors such as patient age and activity levels, weight, bone and muscle conditions.Potential causes of the reported event could include but are not limited to size of device used, surgical technique or procedural/user variance.No further investigation is warranted for this complaint; however we will continue to monitor for future complaints and investigate as necessary.Should additional information be received, the complaint will be reopened.We consider this investigation closed.
