Is medial open wedge high tibial osteotomy is good option for unicondylar osteoarthritis of knee? A prospective study

Abstract

Introduction: A recent World Health Organization report on the worldwide burden of disease suggests that knee Osteoarthritis (OA) alone is likely to become the 4th most important cause of disability in women and the 8th in men. High tibial osteotomy is an accepted surgical technique for the treatment of medial compartment osteoarthritis of the knee in younger patients, It will provide relief of pain and deformity and preserve normal anatomical structure in a selected patient. Aims and Objective: High tibial osteotomy and Unicondylar knee replacement (Or Total knee replacement) are the mainstay of treatment for Medial compartment OA knee. Here we analyzed the functional outcome of the High tibial osteotomy for the medial compartment OA knee. Methodology: Prospective study was conducted for 2 years (2019-2021) among 30 patients who meet our criteria, with a mean age group of 47.33 years (26-58), with mean BMI of 25.22kg/m2 (22-29), the selected patient underwent medial open wedge high tibial osteotomy with plate & screw fixation, with or without bone grafting, on follow up visits patients are evaluated at 6 weeks,3 months,6 months and 1 year clinically, radiologically & complications noted. Based on these data final outcome was assessed with a Knee society score. Results: All patients showed progressive improvement in Range of motions, pain relief, return to normal activities and improved assessment scores.At the end of 1 year mean knee society score improved to 185.67 from 98.83 (P value
