Abstract
We report a case of 69-year-old female patient who presented with a dislocated insert causing tibial component failure and catastrophic metallosis after 4 years of prosthesis implantation. In case of a trauma history, surgeons must suspect friction noise and motion loss as clinical symptoms indicating dislocation of the insert at the initial postoperative period. Timely diagnosis can prevent catastrophic consequences.
