The Spleen(SP)

Descending genicular artery, articular branch: This artery arises from the femoral artery and gives rise to muscular and articular branches. It anastomoses with the superior and inferior medial genicular arteries. The descending genicular artery passes through the opening in the adductor magnus tendon to branch into a saphenous and articular branch. The saphenous branch of the descending genicular artery follows the saphenous nerve along the medial aspect of the knee and the SP channel. The articular branches anastomoses with the medial superior genicular artery within the substance of the vastus medialis muscle, not far from SP 10.

To date, there is no clinical evidence for the effects of pes anserinus. However, theoretically speaking, using the descending genicular artery for the chimeric flap has several unique advantages. In case the descending genicular artery is present, the combination of descending genicular artery flap and the other different tissue flaps could be applied to repair a defect in complex tissues. In case the descending genicular artery is absent, combining the saphenous artery and the osteoarticular artery flaps could also be a good option for reconstruction of complex injuries. Moreover, one branch of descending genicular artery forming an arch with the superior lateral genicular artery and supplying the knee joint [20]. Previous studies confirmed that the medial femoral condyle were supplied by the descending genicular artery or the superior medial genicular artery. The pattern of nutrient vessels may affect the size of periosteal and osteochondral flaps [21]. Thus, clear preoperative imaging seems necessary if a flap based upon this pedicle is to be considered. Moreover, the descending genicular artery chimeric flap, with its two long branches (the saphenous artery and the osteoarticular artery), possesses a long chimeric arm that could be used to repair different tissues in different positions.

The sural artery and descending genicular artery have traditionally been used for flap construction around the knee following trauma. However, these vessels have disadvantages, having an intramuscular course which complicates dissection, and a relatively superficial location which makes them prone to damage following knee trauma.
