The authors report a case of an angioleiomyoma at the anteromedial side of the knee mimicking a neurinoma of the infrapatellar branch of the saphenous nerve. Angioleiomyomas are benign soft tissue tumors with a predilection for the lower extremities in middle-aged females. Paroxysmal pain is triggered by pressure, cold and hormonal changes. Simple excision is usually curative.

The infrapatellar branch of the saphenous nerve (IBSN) is purely sensory and innervates both the anteromedial aspect of the knee and the anterior-inferior portion of the knee capsule. The IBSN arises from the saphenous nerve in the adductor hiatus before piercing the fascia lata to become subcutaneous. Infrapatellar pain syndrome (IPS), also known as an infrapatellar nerve injury, is not a wide...

BACKGROUND If a transverse incision can be safely used for total knee arthroplasty (TKA), decreases in scar formation, reduced injury of the infrapatellar branch of the saphenous nerve and improved kneeling motion will be observed. METHODS We evaluated 95 patients (101 knees) on whom primary TKA was performed with follow-up of more than 2 years. A longitudinal incision was used for the first ...

The saphenous nerve is the longest branch of the femoral nerve and is a purely sensory nerve. It arises from the 3rd and 4th lumbar roots. As mentioned it is an exclusively sensory. It supplies the medial articulation of the knee and cutaneous sensation of the medial aspect of the knee, leg and ankle. The nerve travels in close proximity to the femoral vessels subsartorial. This hunter canal is...
