Editing Tibia (section)

====Facets====
The superior articular surface presents two smooth articular [[facet]]s.
* The '''medial facet''', oval in shape, is slightly concave from side to side, and from before backward. 
* The '''lateral''', nearly circular, is concave from side to side, but slightly convex from before backward, especially at its posterior part, where it is prolonged on to the posterior surface for a short distance.

The central portions of these facets articulate with the condyles of the [[femur]], while their peripheral portions support the [[Meniscus (anatomy)|menisci]] of the [[knee]] joint, which here intervene between the two bones.
