Saphenous Neuropathy

Abstract

Burning pain at the medial thigh or knee area with aggravation after physical activity (such as running) may be caused by saphenous nerve entrapment at the adductor canal. Saphenous neuropathy may arise spontaneously or secondary to trauma or a surgical procedure. The differential diagnosis includes knee pathologies (e.g., medial meniscal tear or patellofemoral disorders) and others. Venous insufficiency may also mimic symptoms of saphenous entrapment syndrome. Careful anamnesis and examination as well as a saphenous nerve block help to make the right diagnosis. If conservative management with physical therapy and pain medication is not effective, surgical options include neurolysis or neurectomy of the saphenous nerve.
