Osteochondral lesions of the knee are relatively common both in young and senior population. The very disabling clinical symptoms, in association to the scarce regenerative capacity of the articular cartilage and the increased risk of developing a secondary osteoarthritis make an effective treatment mandatory. From December 2008 to January 2013, 34 patients (35 knees), 24 males and 10 females (mean age 36.2 years range 14–66) underwent implant of Maioregen® (Finceramica Faenza S.P.A, Italy) biomimetic tri-layer osteochondral scaffold. In 17 cases the osteochondral lesion was cause by an osteochondritis dissecans (acute or sequela), in 13 cases by a spontaneous osteonecrosis and in 4 cases the etiology was traumatic. Patients were evaluated with subjective IKDC and Tegner Lysholm scores, VAS and Tegner Activity Scale before surgery and at regular follow up (mean follow up 38.4 months, range 13 months max 63 months).Purpose

MATERIALS AND METHODS
Different surgical approaches have been proposed for the treatment of chondral lesions. However surgical management of osteochondral defects of the knee joint involving subchondral bone are still under debate. The aim of this prospective non-randomized uncontrolled clinical investigation is to confirm the effectiveness of a commercially available biomimetic osteochondral scaffold in regenerating cartilage and subchondral bone of severe osteochondral lesions of the knee joint with one step surgery.Background:
