描述

The posterior surface of patella presents above a smooth, oval, articular surface, divided into two facets by a vertical ridge; the ridge corresponds to the groove on the patellar surface of the femur, and the facets to the medial and lateral parts of the same surface; the lateral facet is the broader and deeper. Below the articular surface is a rough, convex, non-articular area, the lower half of which gives attachment to the ligamentum patellæ; the upper half is separated from the head of the tibia by adipose tissue.
