title: UKA can be safely revised to primary knee arthroplasty by using an autologous bone plate from the proximal lateral tibia.
abstract: The bone-preservation by UKA in medial osteoarthritis constitutes only an advantage if in the case of revision an unconstrained TKA can be implanted. The aim of this study was to evaluate a revision technique using an autologous bone slice from the lateral to the medial proximal tibia. We report on 17 patients with a mean follow up of 3.1years. Patient's satisfaction and pain, WOMAC- and Oxford-Knee-Score, radiological and clinical knee symptoms/function were assessed. No loosening, wear or implant subsidence could be detected during the follow up. In comparison with results after primary TKA in the literature we found our clinical results to be within the range. The study demonstrates that thismethod is safe and produces good midterm results.
