An event regarding alleged pain and loosening involving a mako insert was reported.Conclusion: there is no indication that the product reported in this investigation contributed to the event however, based on the medical review the most likely sources of the alleged symptoms described are ¿soft tissue imbalance and progression of osteoarthritis to the other compartments.¿ the insert is an integral part of the tibial component construct and will have to be explanted together with the loose baseplate and no other allegations were made against the insert therefore it is considered as concomitant.No further investigation is required at this time.If additional information becomes available to indicate further evaluation is warranted, this record will be reopened.
