Some risk factors of knee osteoarthritis among patients who underwent high tibial osteotomy

Abstract

Background: High tibial osteotomy (HTO) is a widely performed procedure to treat medial knee osteoarthritis. Every year the number of patients who undergo high tibial osteotomy due to knee osteoarthritis is increasing however etiology of knee osteoarthritis is still unclear. Aim: The aim of this study was to investigate the risk factors of knee osteoarthritis among patients who underwent high tibial osteotomy. Materials and Methods: Between 2019 and 2021, one hundred patients were randomized to receive high tibial osteotomy. The data that we reviewed included body mass index, age, gender, non-surgical treatment that patients had, smoking and osteoarthritis stage. Data analysis calculated by using Stata 13.0. Results: Sixty-six percent of the participants were overweight or obese with BMI, and 42% of the participants had KL-III. Regarding with Kellgren Laurence classification, 24 percent of the total patients was in I grade while 34% and 42% of the total patients were in II grade and in III grade respectively. The average age of patients who were diagnosed with KL I grade was 44±6 whereas the average age of those who had KL II grade osteoarthritis was 52±5 and the average age of patients who were in the KL III grade group was 54±4 (p=0.0001). Conclusions: The main risk factors of knee osteoarthritis among the patients who underwent high tibial osteotomy were body mass index and age.
