It lies between the articular facets of the proximal tibia, but nearer the posterior than the anterior aspect of the bone, surmounted on either side by a prominent tubercle, on to the sides of which the articular facets are prolonged.

s emerge from the eminence: * The medial intercondylar tubercle is a protrusion on the medial condyle. * The lateral intercondylar tubercle is a protrusion on the lateral condyle. It can be involved in fractures.

Posterior area

Posteriorly, the medial condyle and lateral condyle are separated from each other by a shallow depression, the posterior intercondyloid fossa (or intercondylar area), which gives attachment to part of the
