Abstract: The invention relates to a surgical guide (1, 1?) for implanting a knee prosthesis, advantageously capable of allowing the intraoperative balancing of the knee ligaments, comprising: a first component (G1, G1?) intended for uniquely coupling with the distal epiphyseal end (Ed) of a femur (Fe); a template (Gr, Gr?) rotatably mounted with respect to said first component (G1, G1?) and intended for guiding a marking operation of said distal epiphyseal end (Ed) aimed to determine the position of a knee prosthesis to be implanted; and a second component (G2) intended for solidly coupling said template (Gr, Gr?) with a proximal epiphyseal end (Ep) of a tibia (Ti) corresponding to said femur (Fe).

Abstract: The device, tool, instrument and the like, for patellar resurfacing, according to the invention, comprises at least one bearing framework (IN), which incorporates a cutting slot (Tpg) and a lower support guide (G2) which may assume different positions with respect to the center of the patellar articular surface. The device is completed by an upper support guide (G1) of the patella for maintaining the shape-constraint coupling between the bearing framework and the patella. Advantageously the device uses the peripheral surface (and not the central one) of said patella, guaranteeing minimal invasiveness and perfect visibility.
