Recruitment & Eligibility

• Status: ot Recruiting
• Sex: All
• Target Recruitment: 36

Inclusion Criteria

• adults subjects; 18 to 60 years old of either sex with symptomatic knee cartilage injury who are eligible for MFx surgery on the femoral articular surfaces, with intact subchondral bone.
• Intraoperative inclusion criteria require that there be one or two focal chondral lesions per target knee and that each lesion satisfy all of the following criteria after peripheral debridement to healthy cartilage: (1) area between 1 and 4 cm2 (inclusive), (2) depth = 6 mm, and (3) arthroscopic confirmation that the lesion is a non-osteochondritis dissecans (OCD) lesion between International Cartilage Repair Society (ICRS) grades I and III (D); a grade III non-OCD lesion is equivalent to an Outerbridge grade IV lesion with minimal subchondral bone loss.
• Subjects must have moderate to severe pain in the target knee prior to surgery, with an average score = 4.0 on the NRS of pain intensity over 7 consecutive days within 30 (+15) days before surgery.
• Subjects must be willing to comply with postoperative and routine clinical and radiographic evaluations, and to follow a standardized rehabilitation program.
• Women of childbearing potential must use a form of contraception with a failure rate of less than 1% per year for the first 24 months of the trial. The use of contraception is also recommended throughout the remaining duration of the trial, due to the planned MRI scans involving gadolinium contrast medium (which is contraindicated in case of pregnancy or breastfeeding) and also because of potential confounding effects of pregnancy on symptoms and trial assessments.
• Written informed consent must be obtained prior to any trial-related activity.

Exclusion Criteria
