Abstract

Saphenous mononeuropathy is an uncommon neuropathy in clinical condition, which may incur from various surgical procedures, direct trauma, or entrapment, and most frequently involves at the adductor canal, or Hunter's canal. A 17-year old female, who was majoring in ballet, visited our rehabilitation clinic for numbness in the medial aspect of the left lower leg for the previous 9 months, without weakness. The electrodiagnostic study revealed only a delayed small potential in the left saphenous nerve. MRI examination showed soft tissue swelling in the medial side of the left knee. Accordingly, we diagnosed the patient with saphenous mononeuropathy around the knee, without lumbar plexopathy or femoral neuropathy. We report a case of saphenous mononeuropathy which developed after repetitive compression on the medial side of the knee without any other iatrogenic injury, and include a review of the relevant literature.

Key Words: Saphenous neuropathy, Ballerina, Compression
