A tibial baseplate for tibial component of a knee prosthesis including: a bulk solid portion including a proximally facing surface adapted to accommodate a bearing element for the articulation of a femoral component of the knee prosthesis; a plurality of porous portions integral with the bulk solid portion having a porous portion contacting surface opposite to the proximally facing surface adapted to contact a proximal tibia. Advantageously, the plurality of porous portions are seamlessly incorporated and embedded in the bulk solid portion.

A surgical aid for joints which allows the positioning of mono-compartment or three-compartment prosthetic components so that the isometry of the capsular-ligament tissues of the knee is maintained during the entire range of motion. Such surgical aid comprises: a first element () intended to be positioned in contact with a first bone of a joint; a second element (), intended to be positioned in contact with a second bone of the joint; the first and second element () being movable relatively to one another along at least a first direction (X); a displacement sensor () predisposed for measuring a relative displacement between the first and second element (); an actuator/motor () predisposed for exerting a force that tends to move the first element () and second element () away from one another; a pressure sensor () which measures the force that is exerted between the first and second bone; a processing module () arranged to control the actuator/motor () so as to calculate the variation of the slope arising from the relationship between distance and force; the processing module () receives in input the signal emitted by the displacement sensor (), the force sensor () and the pressure sensor ().

Surgical aid for joints

A prosthesis device () for correct replacing of the articular surfaces of the human ankle joint comprises: a first component () having a spherical convex articular bearing surface (); a second component () having a bearing surface () which has a convex shape in the frontal plane, and concave sulcus in the frontal plane; and a third component () located between said first and second components () and having two surfaces () which are complementary to and engage the upper convex and the lower concave sulcus surfaces () to be fully congruent with the components (). The three components () can be designed from the subject-specific geometry of the ligaments (). The device () can move under natural muscular and ligamentous control, closely restoring that of a natural joint and maintaining uniform load distribution. A prosthesis device () implanted according to a stated method of ensuring equal dorsi- and plantar-flexion gaps between first () and second () components, is a part of the invention.
