Video 1 shows intraoperative findings during the tibial insert exchange. Arthroscopy evidenced an anterior lift-off and complete dissociation of the polyethylene out of the tibial baseplate and discarded other additional causes of painful TKR. Open surgery revealed compression deformation damage at the posterior aspect of the inferior surface of the retrieved polyethylene.
