Traumatic neuroma of the infrapatellar branch of the saphenous nerve after hamstring harvesting.

We describe a case of a 47-year-old man with radiating pain and a palpable subcutaneous nodule on the medial side of the upper leg 10 years after hamstring anterior cruciate ligament reconstruction. Clinical and radiological investigations were highly suggestive for a neuroma of the infrapatellar branch of the saphenous nerve. After surgical excision, the diagnosis of traumatic neuroma was confirmed by pathology evaluation. To our knowledge, no similar case has previously been reported.
