title: Open-Wedge High Tibial Osteotomy Using a Protective Cutting System: Technical Advancement for the Accuracy of the Osteotomy and Avoiding Intraoperative Complications.
abstract: Open-wedge high tibial osteotomy for medial unicompartmental arthritis of the knee joint is a successful treatment option but is associated with potential intraoperative complications such as tibial plateau fracture, dislocation of the osteotomy hinge, under- or over-correction of the posterior slope, and neurovascular injury. Therefore we devised a protective cutting system and describe our method for the prevention of these complications. The potential advantages of this system are protection of the posterior neurovascular structures using a curved protector, bone cutting along the natural tibial slope using a superior surface aligning with the natural tibial slope, and complete 1-plane sawing of the posterior wall before the lateral hinge.
