Unicompartmental knee arthroplasty appeared at the 70s as an alternative to the proximal tibial osteotomyin young patients with pain and medial or lateral compartment osteoarthritis of the knee. At the 90s this technique began to be abandoned because the clinical results were not the expected. In the last years, lots of articles have been published showing results that can be compared with the total knee arthroplasty thanks to the news designs and the improve of the surgical technique. A retrospective study was made of the 25 unicompartmental knee arthroplasties performedin our hospital, with a mean follow up of 65 months. We analysed the range of mobility, the need of revisionsurgery and the Knee Society Score, getting similar results to that that made abandon the technique in the 90s.
