This case report describes a
43-year-old woman with a previous anterior cruciate
ligament reconstruction and medial meniscectomy who presented with right knee
dysesthesias radiating into her medial ankle with associated allodynia. An
extensive work-up was pursued, without a definitive diagnosis found or
improvement in the patient's symptoms. Eventually, she was referred to Pain
Medicine for an ultrasound-guided saphenous nerve (SN) block, where a scan before
the injection revealed a large cyst anteromedial to the sartorius in the expected
location of the SN. Magnetic resonance imaging and surgical pathology confirmed a
juxta-articular ganglion cyst compressing the main SN, just above the take-off of
the infrapatellar branch.
The cyst was successfully resected, with improvement
noted in the patient's neuropathic symptoms postoperatively. Saphenous neuropathy
is a rare condition, and to our knowledge this case is the first reported of
saphenous neuropathy caused by a knee joint capsule-derived ganglion cyst.
