Clinical and Radiographic Outcomes of Medial Open-wedge High Tibial Osteotomy
Keywords
Abstract
Description
The investigators will conduct a retrospective case-series study of at least 40 patients , who underwent medial open-wedge HTO for treatment of medial knee osteoarthritis between January 2016 and January 2019 in our Arthroscopy and Sports Injuries Unit in Orthopaedics Department of Assiut University. 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.
Post-operative :
follow up after at least 1 year post-operative clinically using knee society score (KSS) , visual analogue scale (VAS),Knee Injury and Osteoarthritis Outcome Score(KOOS) , Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index scores and radiological assessment using Anteroposterior and lateral views xrays assessing union two-leg long standing view x ray with or without slight flexion assessing Femoral-tibial angle (FTA) and joint line .
