Purpose: Medial open wedge high tibial osteotomy (MOWHTO) is an effective surgical procedure for patients who have medial compartmental osteoarthritis of the knee with varus deformity of the limb. The abnormal load on the medial compartment of the knee is directed to the lateral compartment with this procedure. A gap occurs on the proximal tibia while providing adequate correction. Filling this gap with bone grafts or synthetic materials has gained wide acceptance for preventing bone union problems or osteotomy site collapse. The aim of this study is to report our results of MOWHTOs performed without any bone graft or any other synthetic materials.
Patients and Methods: We evaluated 20patients MOWHTOs that have been performed between 2014 and 2018. Age of the patients ranged from 18 to 40. Fifteenpatients were females and five of them were males. The follow-up time was 12 months.
Results: All osteotomies united without loss of correction. The meanbone union time was 12.8 weeks. We did not have any major complication regarding the technique.
Conclusion: The results of our study have shown that we can achieve satisfactory and good results by performing MOWHTO procedure without using any bone grafts or synthetic materials.
