A size 28 mm uni onlay insert was implanted on (b)(6) 2018.The patient complained of a squeaking sound on deep flexion.During a revision of the knee, the surgeon explanted the insert as it was not locked into the baseplate.The patient does cross fit training and is very active.We put in another insert.Pka case.Update, as per medical review received: the most obvious problem confirmed both on x-ray and in the mar is malalignment between femoral and tibial component with symptoms of metal contact between devices.The malalignment is caused by incomplete locking of the poly liner in the baseplate as reported from the revision surgery.
