Superomedial Genicular Nerve, Medial View

Description

Arising along the medial aspect of the distal femur, the superomedial genicular nerve courses anterior to the adductor tubercle region and then curves toward the superomedial margin of the patella and knee joint capsule, running just proximal to the joint line. Medially, the femoral medial epicondyle sits superior to the medial tibial plateau, while the patella lies anterior to the femoral trochlea. Articular cartilage caps the opposing femoral and tibial surfaces, and a thin capsular envelope outlines the synovial joint. Fine. A medial perspective like this matters when you need to localize articular sensory supply for pain procedures around the knee. The superomedial genicular nerve is a common target for genicular nerve radiofrequency ablation in chronic knee osteoarthritis, and its relationship to the superomedial quadrant of the patella, the medial femoral condyle, and the capsular reflection helps explain why slight changes in needle depth can shift you from periosteal contact to extra-articular soft tissue. Surgical dissection and arthrotomy planning also benefit from understanding where small articular branches run near the capsule, since iatrogenic neuritis can follow medial incisions or aggressive electrocautery in the peripatellar retinaculum. Use this plate in regional anesthesia teaching (genicular nerve blocks, RF ablation targeting), musculoskeletal anatomy courses covering knee innervation, or as a figure in orthopedic and pain medicine publications discussing periarticular sources of anterior and medial knee pain. It also supports patient-facing education when explaining why pain can persist despite intra-articular injections, given the extra-articular capsular innervation pattern.
