Event Description

Information was received based on a review of a journal article titled, "valgus subsidence of the tibial component in cementless oxford unicompartmental knee replacement," which aimed to examine the clinical and radiological findings of patients whose tibial component subsides into a valgus positions with an increased posterior slope before becoming well-fixed.The situation appears to be avoidable by minor modifications to the operative technique, and it appears that it can be treated conservatively in most patients.It has been reported in the journal article that a patient experienced pain and limited mobility.A radiograph indicated subsidence and was subsequently revised.During the procedure, impingement was noted.The joint was debrided and the tibial bearing was replaced with a thicker bearing.
