Inclusion criteria is Kellgren-Lawrence classification grades 1 to 3; symptomatic unicompartmental osteoarthritis Pre-operative : assessment of patients is done clinically using Knee society score (KSS) and visual analogue scale (VAS) (0 mm, no pain;100 mm, worst pain) and radiographic assessment according to Kellgren and Lawrence using anteroposterior (AP) and lateral x-ray views of the knee , a two-leg long standing view with or without slight flexion assessing Femoral-tibial angle (FTA) . Intra-operative : After anaesthesia is induced, an arthroscopic examination is performed to define the status of the menisci (excluding significant damage of the lateral compartment), cruciate ligaments, and articular cartilage. meniscal surgery (partial menisectomy/meniscal repair) is performed when necessary, then The medial open wedge high tibial osteotomy (MOWHTO) is performed.
