Osteotomy chày IS có hiệu quả cao để quản lý một đa dạng của điều kiện đầu gối, bao gồm gonarthrosis vẹo với vàng malalignment valgus, osteochondritis dissecans, hoại tử xương, sự mất ổn định posterolateral, và nổi bọt chondral. Các mục tiêu cơ bản của thủ tục được dỡ bỏ các bề mặt khớp và biến dạng | High Tibial Osteotomy John M. Wright MD Heber C. Crockett MD Daniel P. Slawski MD Mike W. Madsen MD and Russell E. Windsor MD Abstract High tibial osteotomy is effective for managing a variety of knee conditions including gonarthrosis with varus or valgus malalignment osteochondritis dissecans osteonecrosis posterolateral instability and chondral resurfacing. The fundamental goals of the procedure are to unload diseased articular surfaces and to correct angular deformity at the tibiofemoral articulation. Although the clinical success of total knee arthroplasty has resulted in fewer high tibial osteotomies being done during the past decade the procedure remains useful in appropriately selected patients with unicompartmental knee disease. Renewed interest in high tibial osteotomy has occurred for a number of reasons. These include the prevalence of physiologically young active patients presenting with medial compartment osteoarthritis the advent of new techniques for performing the procedure ie improved instrumentation and fixation plates for medial opening wedge osteotomy dynamic external fixation for medial opening wedge osteotomy and improved instrumentation for lateral closing wedge osteotomy and the need to concomitantly correct malalignment when performing chondral resurfacing procedures ie autologous chondrocyte transplantation mosaicplasty and microfracture . J Am Acad Orthop Surg 2005 13 279-289 teoarthritis in physiologically young active patients for whom TKA is an imperfect long-term solution. 2 HTO imposes no permanent activity restrictions whereas concerns about durability mandate activity modification after TKA. 3 Superior results are more likely with contemporary fixation and postoperative management techniques after HTO than with antiquated techniques requiring several weeks of postoperative cast immobilization. 4 Evolving chondral resurfacing techniques are contraindicated in the presence of tibiofemoral malalignment because they Osteotomy of the .
