ObjectiveTo summarize the clinical application and research status of open wedge high tibial osteotomy (OWHTO).MethodsRelevant literature at home and abroad was reviewed, and the clinical application, effectiveness and complications, technical comparison, and surgical skills of OWHTO were summarized and analyzed.ResultsOWHTO is an effective treatment for mild to moderate medial compartment osteoarthritis due to knee varus. This method can delay the injury process of medial compartment of the knee, delay the time of total knee arthroplasty, and even avoid joint replacement surgery by adjusting the axial alignment of the lower extremity to the non-pathological lateral compartment through osteotomy and orthopedic. OWHTO has the advantages of small incision, dynamic adjustment of the axial alignment of the lower extremity, accurate correction of malformation, and rapid postoperative recovery.ConclusionWith the development of surgical instruments and techniques, OWHTO once again enter the sight of orthopedic surgeons. This technique can solve the pain symptoms of arthritis, correct the tibial varus deformity and reconstruct the axial alignment of the lower extremity, and satisfactory clinical results has been obtained.
