Twelve to 84% of patients describe hypo or dysaesthesia secondary to injury of the saphenous nerve or one of its branches after hamstring harvesting. Type of incision (orientation and length) is subject of much debate to limit the risk of nerve damage.

Distance between saphenous nerve branches and 4 points of interest along the tibial crest was measured.

Each incision was modelled for three lengths (2, 3 and 4cm).
