Ankles from 100 cadavers were dissected to evaluate the risk of nerve injury from an arthroscopic procedure. A total of 65 cadavers (104 ankles) were examined to assess the course of the peroneal nerve, and 35 cadavers (77 ankles) were examined for the saphenous nerve (SN). ⋯ At the anteromedial portal site, between the medial border of the talocrural joint and the tibialis anterior tendon, the SN coursed an average of 6 +/- 5 mm medial to the medial border of the talocrural joint. SNs in this area were all terminal branches; therefore, anteromedial portal placement avoids nerve injury.
