Periarticular nodes

The periarticular region is the anterior outer edge of the distal epiphysis of long tubular bones.

In the age aspect, the periarticular area, including the interosseous membrane and periarticular tissues, is conventionally divided into intracapital and extracapital areas, and the boundary between them is difficult to draw, since the cover over the epiphysis of the femur passes directly into the interosseous space of the knee joint. The thickness of the subcutaneous fat increases slightly anteriorly (along the internal intercondylar line) towards the patella and represents the edge of the thick fibrous layer of the capsular ligamentous apparatus of the joint. The articulating proximal surface of the interosseous membrane consists almost entirely of cartilage, penetrated by intra-articular fibers of the main (external) capsular-ligamentous complex. In the process of development, a depression of the articular fossa is formed from this cartilaginous part of the shell along with the articular disc, which carries the articular capsule and lig. collaterale majus and minimus and intercondylaria lateralia. In the periarticular region, there is a dorsal zone, consisting of the femoro-dipphyseal ligamentous apparatus, and two lateral lateral zones, consisting of ligaments running across the leg (lig. extensorum laterale, longum quadricipitis, liberum). Thus, the periarticular zone of the femoral distaffesis enclosed in the interosseous fascial membrane
