Subsartorius Fascial Plane Hydrodissection as Novel Treatment for Hunter's Canal Syndrome.

Saphenous entrapment neuropathy in the distal thigh most commonly occurs at Hunter's canal and is characterized by neurologic symptoms distal to the midthigh in the saphenous nerve distribution. Presented is a 23-year-old active duty female service member with left medial knee pain worse with knee flexion and extension. Evaluation raised suspicion for saphenous nerve entrapment at Hunter's canal, and ultrasound-guided subsartorius fascial plane hydrodissection was performed in addition to focused rehabilitation of the adductor and core musculature. No reports of this treatment have been published to date. This case introduces ultrasound-guided subsartorius fascial plane hydrodissection as novel treatment in Hunter's canal syndrome.
