A tibial-femoral trial implant comprises a femoral trial insert, which comprises a medial condyle and a lateral condyle, and a tibial trial insert, which comprises a medial plate and a lateral plate. The implant further comprises a graduated reference system adapted to indicate the relative angular deviation between the femoral trial insert and the tibial trial insert about a vertical axis, passing through the center of a sphere defining the medial condyle of the femoral trial insert, following a roto-translational movement of the femoral trial insert from a first position, identifying a knee extension position, to a second position, identifying a knee flexion position.
