Answer

Nerve injuries causing medial joint pain include trauma to the infrapatellar branch of the saphenous nerve and injury during knee surgery, especially arthroscopy. Pain can be reproduced with the Tinel sign. One case report documents distal tibial pain from entrapment of the saphenous nerve caused by pes anserine bursitis. [25] Medial knee pain associated with back pain also could represent an L3-L4 radiculopathy. Electrodiagnostic tests, such as electromyography (EMG) and nerve conduction velocity tests, may be useful.
