Официальное название
Open Wedge High Tibial Osteotomy Versus Double Level Osteotomy
Обзор
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.
Подробное описание
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).
Вмешательства
- Процедура Open Wedge High Tibial Osteotomy
For OWHTO,The osteotomy plane, directed from 30 to 35 mm distal to the medial tibial plateau to 10-15 mm distal to the lateral tibial plateau in the coronal plane, was marked by two Kirschner wires with threaded tips. A transverse osteotomy was performed, leaving the lateral cortex intact as a hinge. After the ascending osteotomy and opening. The medial opening gap was filled with two β-TCP wedges and fixed with a TomoFix anatomical plate and locking screws . - Процедура Double Level Osteotomy
The DLO was started from a lateral DFO. A 5-6-cm incision was made proximally at the distal femur from the lateral femoral epicondyle.Two Kirschner wires with threaded tips were inserted to make a length between the wires that was preoperatively planned as the lateral closed osteotomy. Transverse and ascending osteotomies were performed using a Precision Oscillating Tip Saw. The gap was closed and fixed using a TomoFix medial distal femur anatomical plate , which was bent for the lateral distal
