Bilateral nerve entrapment in the popliteal space

We report a rare case of bilateral idiopathic nerve entrapment in the popliteal space causing knee pain. Decompression gave relief of the symptoms and the patient remained symptom-free at followup five years after surgery. Although the case presented is of a rare condition, it is an important differential diagnosis in patients presenting with pain in the posterior aspect of the knee, especially if the pain is associated with activity. The most important physical finding is local tenderness over the area of suspected entrapment.
