Our results of high tibial osteotomy in medial knee osteoarthritis

Abstract

Aim: Knee osteoarthritis is very common and causes serious dysfunction of the joint. HTO is the most commonly used method in cases of active and young patients suffering from medial knee osteoarthritis. Although many techniques have been described for HTO, opening-wedge osteotomy is the most commonly used method. Given the rare availability and osteointegration of the allograft, autograft use is more common. In our clinic, we prefer using ipsilateral autografts. Grafts of different sizes were taken for each patient. In this study, we aimed to introduce this procedure and investigate the effect of surgical treatment on outcome. Material and Methods: WOMAC, Lyslom score, knee ROM, and mechanical axis were evaluated in 32 patients with a mean age of 53 years. We fixed the mechanical axis using the lamina spacer and cable method during HTO surgery. After autograft placement, we provided fixation with a locked T-plate. Results: While there was a statistically significant improvement in WOMAC, Lyslom score, and mechanical axis values, there was no significant difference in ROM value. Good and excellent results were achieved in all patients except one. Discussion: The rate of excellent results increases in younger patients, which is consistent with the literature. HTO, which is applied with appropriate patient selection and the right technique, can be used safely and successfully in knee medial osteoarthritis. In HTO surgeries performed in our clinic, we take autografts of different sizes according to the degree of correction in each patient. We think that this autograft retrieval technique facilitates surgery and contributes to stability.
