A study of functional outcome of medial open wedge verses lateral closed wedge high tibial osteotomy

Abstract

The treatment of unicompartmental osteoarthritis with high tibial osteotomy using medial open wedge verses lateral closed wedge osteotomy. It is a choice of surgery in young age osteoarthritis. In this study we analyse the functional outcome of medial open wedge osteotomy the tom fix plate and lateral closed wedge osteotomy using staple in patients having unicompartmental osteoarthritis with genu varum.Material and Methods: This is a prospective study of patients who attended the orthopaedic outpatient clinic in tertiary care hospital between July 2021 to December 2022. The patients were evaluated by clinical examination and weight bearing radiographs. The patients who were found to have unicompartmental osteoarthritis with knee pain not relieved by conservative management and who satisfy the inclusion criteria were selected. During this period 30 patients were selected and were included in study.Results: In both groups a significant improvement of both scores were achieved. Both methods obtained safe and reproducible results for the correction considering the different operation techniques. There were no differences in outcome between the two methods. Satisfactory results were also achieved for early arthrosis of the femoropatellar and the lateral compartment.Conclusion: Open and closed wedge HTOs obtain significant improvement in patients with medial osteoarthritis of the knee. Using the right technique is very important for good results. For stabilization of the medial ligament we recommend the open wedge osteotomy. The patient should be informed about the routine removal of the metal plate.
