The descending genicular nerve is a branch of the saphenous nerve (femoral nerve) that accompanies the descending genicular artery, providing sensory supply to the medial knee capsule and skin. It is one of the three primary targets in medial genicular nerve ablation for knee OA.
The descending genicular nerve is the medial superior genicular nerve target for radiofrequency ablation in knee OA, providing the major sensory supply to the anteromedial knee capsule. Its fluoroscopic landmark is the superomedial femoral condyle. Accurate ablation of this nerve alongside the medial inferior genicular nerve and superolateral genicular nerve achieves the most complete knee denervation for chronic OA pain management.
Radiofrequency ablation of the descending genicular (saphenous) nerve branch at the superomedial femoral condyle as part of the standard three-nerve knee denervation protocol, providing 6-18 months of knee OA pain relief.
