Comparison Of Results Of High Tibial Osteotomy Using Open Wedge Versus Close Wedge In Medial Uni- Compartmental Osteoarthritis Of Knee

ABSTRACT

Background: Osteoarthritis is now considered to be primarily a disease of cartilage in which intrinsic biomechanical and mechanical alterations lead to its breakdown. Increasing failure of conservative treatment lead surgeons to explore the operative arena. High Tibial Osteotomy (HTO) is a satisfactory surgical method in knees with unicompartmental osteoarthritis and angular deformity. Objectives: To manage medial uni-compartment osteoarthritis of knee with medial open wedge or lateral closing wedge osteotomy and to compare between the two. Methods: HTO of 20 adult patients with medial compartment osteoarthritis or medial bicompartment osteoarthritis with genu varum deformity and their followup with functional and radiological parameters. Results: Following operation 12 patients having excellent results & 8 patients (40%) having good results. 19(95%) patients were satisfied. Conclusion: There is no significant statistical difference between the patients undergoing medial open wedge and lateral close wedge high tibial osteotomy except for medial joint space. Medial Open Wedge is technically easy with fewer risks, hence preferred over lateral close wedge.
