摘要：
This invention relates to a surgical device for preparing the knee joint of a patient undergoing to partial knee replacement. The device is patient specific and has information about implant size, alignment and bone cut.This device consists of two parts, one is related to femoral template and the other one is related to tibial template. The femoral template positioned to a predefined location on the femur bone based on virtual planning of the surgery on specific software using 3D imaging. The femoral template allows to perform the posterior distal cut, drill and detect the location of the two holes relevant to the distal cut and implant pegs, while the tibial template allows the surgeon to make the tibial horizontal and vertical cuts； beside that, it has double slots which allows the surgeon to make extra bone removal if needed or when deciding to use larger size of polyethylene insert.
