Case Reports
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.

The purpose of this study was to document the pattern of ligament and meniscal injuries that occur during high-energy tibial plateau fractures. One hundred three patients with fractures due to high-energy mechanisms were evaluated with knee magnetic resonance imaging (MRI). All studies were read by a single musculoskeletal radiologist who was blinded to surgical and physical exam findings. ⋯ Tibial plateau fractures frequently have important soft tissue injuries that are difficult to diagnose on physical examination. High-energy fracture patterns (AO/OTA type 41C or Schatzker type IV, V, VI) clearly have a significantly higher incidence of ligament injury, and these patients should be carefully evaluated to rule out a spontaneously reduced knee dislocation. We believe MRI scanning should be considered for tibial plateau fractures due to high-energy mechanism, allowing identification and treatment of associated soft tissue injuries.
