EVALUATION OF FUNCTIONAL RESULTS OF MEDIAL OPENING WEDGE HIGH TIBIAL OSTEOTOMY FOR UNICOMPARTMENTAL OSTEOARTHRITIS VARUS KNEE
Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2017, Vol 4, Issue 1
Abstract
BACKGROUND Osteoarthritis commonly affects the medial compartment of knee giving rise to varus deformity in majority of cases. Significant varus deformity further aggravates the pathology due to medialisation of the weight bearing line osteotomy of the proximal tibia realigns this weight bearing axis, thereby relieving pressure on the damaged medial compartment. OWHTO is a promising option in this scenario because it is associated with high accuracy in correcting the deformity and less number of complications when compared to lateral closing wedge HTO or UKA. In this study, we evaluate the functional outcome of HTO in patients with unicompartmental osteoarthritis. MATERIALS AND METHODS This is a prospective study of patients who attended the orthopaedic outpatient clinic in Government Hospital, Kakinada, between August 2013 to August 2015. 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. RESULTS Excellent results can be achieved by appropriate selection criteria and planning with long limb weight bearing radiographs. There is an excellent relief of pain, which can be achieved within first few months postoperatively, which is assessed by VAS score. The KSS- knee score is excellent in 35%, good in 40%, fair in 20% and poor in 5%. The KSS- function score is excellent in 30%, good in 45%, fair in 20% and poor in 5%. There is significant improvement in the range of movement of the knee joint postoperatively. CONCLUSION In this study, we conclude that medial OWHTO is the preferred modality for unicompartmental OA in those aged <60 years and in developing nations like India where squatting is an important function, it has major role as it can restore near normal knee function without disturbing anatomy.
