Abstract :
Introduction: High tibial osteotomy (HTO) is a common surgical technique for isolated medial compartment osteoarthritis of tibio-femoral component of knee, indicated in young and active patients with varus deformity. It can be performed by lateral closed wedge osteotomy, medial open wedge osteotomy and dome osteotomy. Purpose of this study was to evaluate the (1) Incidence and severity of complications after medial open wedge osteotomy, (2) functional outcome, (3) survival rate of HTO, (4) incidence of revision to TKR.
Materials And Methods: We have retrospectively evaluated 32 knees in 27 patients operated during last 10yrs (January 2005 to May 2015) who have undergone Medial open wedge HTO for Unicompartmental (medial) OA of knee. The indications for surgery were medial compartment osteoarthritis with varus deformity of knee, young and active patients with age < 55yrs, progressive symptoms unresponsive to conservative treatment for at least 6 months, >90˚ of flexion, flexion contracture 90˚, with flexion contracture < 10˚. It is less expensive and no changes in lifestyle are required which is very useful in Indian perspective. It retains all the pre-operative movements and helps in delaying total knee arthroplasty.
