A knee prosthetic including a tibia part, which includes a tibia plate that cooperates with at least one meniscal element by a first side, and cooperates with a tibia resection plan by a second side, including:a tibia pin connected with the tibia plate which penetrates into the tibia to fix the tibia part into it; and at least one compensating tibia block which fits flatly between the second side of the tibia plate and the tibia itself, in order to compensate for a lack or absence of local bone tissue between the tibia and the resection plan, wherein said tibia block also cooperates with said tibia part by way of complementary fixating means that are implemented on the tibia block and tibia part, wherein the complementary fixating means are of the pin and hole type and are implemented on the tibia block and the base of the tibia pin, wherein the fixating means include at least one ridge which allows for the alteration of the shape of the material to achieve an elastic clasping between the hole and the pin, and/or the penetration of the pin in the hole, and wherein a ridge extends in the pin, along and on at least part of its length until its free extremity in order to define two flexing tongues.
