∑ Presents two smooth and concave articular facets
∑ The medial facet, oval in shape, is slightly concave from side to side, and from front to back.
∑ The lateral, nearly circular, is concave from side to side.
∑ The central portions of these facets articulate with the condyles of the femur.
∑ Their peripheral portions support the menisci of the knee-joint.
∑ Between the articular facets, closer to the posterior than the anterior aspect of the bone, are the intercondylar eminences.
∑ Its medial surface is convex, rough, and prominent; it gives attachment to the medial collateral ligament.
∑ Presents posteriorly a flat articular facet, nearly circular in form, directed downward, backward, and lateral, for articulation with the head of the fibula.
∑ Its lateral surface is convex, rough, and prominent in front.
∑ The anterior surfaces of the condyles.
∑ Attachment of ligamentum patella (patellar tendon)
∑ On the lateral condyle is an eminence, situated on a level with the upper border of the tuberosity and at the junction of its anterior and lateral surfaces, for the attachment of the iliotibial band.
∑ Between the articular facets, closer to the posterior than the anterior aspect of the bone, is the intercondylar eminences
∑ The lateral surface presents a triangular rough depression for the attachment of the inferior interosseous ligament connecting it with the fibula.
∑ The lower part of this depression is smooth, covered with cartilage and articulates with the fibula.
∑ The medial surface of this process is convex and subcutaneous.
∑ Itís lateral or articular surface is smooth and slightly concave, and articulates with the talus.
∑ The posterior border of medial malleolus presents a broad groove.
∑ The groove lodges the tendons of the tibialis posterior and flexor digitorum longus.
