Zhang Yingze institution found, through a series of studies, that uneven subsidence of the tibial plateau was an important factor in the medial compartment KOA. In order to effectively treat the medial compartment type KOA, the latest research results are that in the proximal fibula osteotomy combined with the tibial high-level osteotomy, a gasket is implanted at the proximal tibia, so that the knee joint force line can be effectively corrected, and meanwhile, the compression fracture or collapse of the tibial plateau can be supported and reset, so that the comprehensive treatment of the knee joint osteoarthritis patients with the excessive varus angle is realized. When the gasket is implanted, the gasket is required to be embedded after the inner side of the tibia is grooved, a row of holes are drilled in the tibia along the horizontal plane in the grooving process, then the holes are communicated into a long groove, and then the gasket is embedded into the long groove. However, in actual operation, the phenomenon of inaccurate or inconsistent drilling angles often occurs, and the phenomenon that a plurality of drilling holes are arranged up and down unevenly affects the final shape of the long groove, which is not beneficial to the operation of placing the gasket.
