Background
Knee joints are the largest and most complex joints in the human body. Knee replacements are used on severely damaged knee joints. As knee replacement becomes the most popular procedure for severe knee injuries, research on knee replacement has also been increasingly emphasized.
Prosthetic knee surface replacement surgery involves the implantation of femoral and tibial prosthetic components between the distal femur and proximal tibia to replace a damaged knee. When the tibia is cut, the accurate bone cutting amount, the accurate bone cutting position and the accurate inclination angle of the bone cutting surface need to be determined.
There are a number of clamps or instruments known in the art for determining the amount of osteotomies, such as: the determination of the osteotomy amount, the osteotomy position and the inclination angle of the osteotomy face is realized by a tibia sounder, but the positions of the clamps or instruments are required to be positioned, and the existing positioner has the defects of difficult positioning, inconvenient adjustment and the like.
