Abstract
AMOA can be treated successfully with either HTO or UKA with excellent short-term outcome in both techniques. However, in this RCT, HTO yielded significantly better OKS which is the primary outcome measure at the final 2-year follow up. HTO also shows better or similar other functional and clinical scores as UKA with comparable rate of complications and reoperation. It is recommended to use UKA for cases with AMOA with mainly intraarticular deformity (JLCA varus > MPTA varus) and to use HTO in cases of AMOA with mainly extraarticular deformity (MPTA varus > JLCA varus) to have the best outcome. However, no significant difference was found if any of them was used instead of the other in the short-term follow up in this study. Mobile bearing UKA is a very successful procedure with very high success rate in management of AMOA. however, bearing dislocation is still among the most common devastating complications that may lead to worse outcome and even conversion to TKA. A learning curve in the performance of UKA and high-volume surgeons can decrease the risk of this complication.
