Medial open wedge high tibial osteotomy (OWHTO) is usually performed with proximal tuberosity osteotomy or setting the osteotomy line proximal to the tuberosity. However, OWHTO can result in patellofemoral complications due to postoperative patella infera. A new OWHTO technique, biplanar osteotomy with a distal tuberosity osteotomy, was reported in 2004 to prevent postoperative patella infera. To ensure that the 2 osteotomy lines maintain perpendicular, we describe the OWHTO procedure with a distal tuberosity osteotomy technique using a TriS Medial HTO Plate System (Olympus Terumo Biomaterials Corp., Tokyo, Japan) and a right angle guide we developed. In this Technical Note, we describe the procedure and advantages, risks, and limitations, as well as the pearls and pitfalls based on our experience.
内侧开放楔形高位胫骨截骨术（OWHTO）通常采用近端结节截骨术或将截骨线设置在结节近端进行。然而，由于术后髌骨低位，OWHTO可能导致髌股关节并发症。2004年报道了一种新的OWHTO技术，即双平面截骨术加远端结节截骨术，以预防术后髌骨低位。为确保两条截骨线保持垂直，我们描述了使用TriS内侧HTO钢板系统（日本东京奥林巴斯泰尔茂生物材料公司）和我们研发的直角导向器的远端结节截骨术技术进行OWHTO手术的过程。在本技术说明中，我们根据经验描述了该手术的过程、优点、风险和局限性，以及要点和陷阱。
