Knee Osteoarthritis

Details and patient eligibility

About

To compare the radiographic and clinical outcomes of varus osteoarthritic knees treated with an open-wedge high tibial osteotomy (OWHTO) alone or with a double-level osteotomy (DLO). It was hypothesized that treatment with DLO would prevent the joint line obliquity (JLO) , optimize post-operative limb alignment and provide better clinical and radiological outcomes after surgery than medial opening-wedge high tibial osteotomy (OWHTO) alone for patients with medial compartment osteoarthritis.

Full description

Osteoarthritis is a degenerative joint disease characterized by erosion of the articular cartilage, hypertrophy of the bone at the margins and subchondral sclerosis(1). Osteoarthritis of the knee is a common problem causing significant knee pain and disability. Medial compartment osteoarthritis is predisposed to be varus deformity of the knee(2). High tibial osteotomy (HTO) is a well-established method for treatment of medial Uni compartmental-knee osteoarthritis and correction of varus deformity(3).Double level osteotomy recently used as another method for treatment this problem to improve outcomes and decrease complication(4).
