Saphenous neuralgia after arthroscopically assisted anterior cruciate ligament reconstruction with a semitendinosus and gracilis tendon graft

A case report of saphenous neuralgia following arthroscopically assisted an terior cruciate ligament reconstruction with hamstring tendons is presented . The patient complained of paresthesia in the anteromedial region of the l ower leg and tenderness at the medial side of the knee without motor or ref lex abnormalities. Because saphenous neuralgia can mimic disorders of the k nee, peripheral vascular disease, and lumbar nerve root compression, diagno sis can be confirmed by anesthetic blockade. The patient underwent saphenou s neurolysis. Six months after surgery, the patient had normal cutaneous se nsation at the medial aspect of the lower leg and ankle and she no longer c omplained of any painful dysesthesia. To minimize the risk of damaging the saphenous nerve when harvesting hamstring tendons, the knee should be flexe d and the hip external rotated.
