A transversal support tibial plateau consisting of two joint surfaces, two
joint surface supports and a transversal support is described. This
transversal support tibial plateau is arranged in such a way that the
joint surfaces can be introduced separately from the front into the knee
joint. This arrangement simplifies the surgical procedure, while the
ventral corticalis is preserved. Owing to the construction with separate
joint surface supports and joint surfaces, the joint surface supports can
first be secured on the transversal support, for example, by means of
support screws. Alternatively, the joint surface supports or the joint
surface units can first be implanted obliquely from above with
preservation of the ventral corticalis and then be received and supported
from the side by a transversal support of corresponding design.
