Arthroscopy portals and skin incisions are marked on the skin with a marking pen. A 2 cm long transverse high medial parapatellar incision lies approximately 1 cm distal to the superior patellar pole and is centered over the medial border of the patella. The whole procedure can be performed without a tourniquet if the incisions and the knee-joint are infiltrated with epinephrine / buivacain solution.
