Inclusion criteria
* Male and female patients between the ages of 18 and 55 * osteochondral lesions of the knee due to trauma or osteochondritis dissecans or removal treatment ( lesion post autograft) * Osteochondral lesion \> grade II- ICRS * One lesion or 2 concomitant lesions (tibial plateau, patella and condyles )at least one lesion has been pretreated by mosaicplasy or ACI. These treatment would have to have been made at least 18 months before inclusion * Presence of disabling and clinically meaningful symptoms (subjective IKDC \< 65, no improvement for 3 months) * No significant obesity (BMI \< 30) * Accompanying ligamentous and meniscal lesions, joint malalignment and patella femoral instability are authorized and corrected concurrently. * Patient able to understand, sign and date the informed consent form * Patient affiliated with a national health insurance system or who is the beneficiary of such as system * Women of childbearing age may not be included in the clinical trial unless their pregnancy test is negative. If this test is negative, they will be asked to use an effective birth control method during the entire the study.
