Inclusion Criteria

Patients presenting an osteocartilaginous femoral single lesion, with a traumatic etiology or an osteochondritis dissecans could be included in this trial only if all the following criteria are met:
•Patients of both sexes, active, between 18 and 45 years.
•Osteochondritis dissecans, type III or IV following the ICRS classification.
•Grade 3 or 4 lesion following the ICRS classification.
•Lesion’s surface (perpendicular measure: L x l) from 2.50 cm2 to 7.00 cm2 measured following debridment during the arthroscopy.
•Lesion’s depth should not be over 10 mm.
•Existence of invalidating symptoms, clinically significant (subjective IKDC score lower than 55).
•No prior surgical treatment of this lesion such as microfracture according to Pridie method or perforation > 4mm validated by MRI and osteochondral autografts or autologous chondrocytes implantation.
