Outcome Measures

Primary Outcomes (1)

  • MOCART score

    The independent evaluator measure the MOCART score based on the MRI images taken at 48 weeks after surgery. The MOCART score is an index for evaluating the degree of restoration of cartilage tissue and consists of a total of 9 items. Each item is scored from 0 to a maximum of 20 points and added up. The MOCART score is 0 when the cartilage is in the worst condition, and 100 when it is in the best condition. In other words, when the clinical effect of tissue repair appears, it is evaluated as a score greater than 0.

    From 48 weeks after surgery

Secondary Outcomes (7)

  • IKDC score

    Baseline and 12, 24, 48 weeks after surgery

  • VAS

    Baseline and 12, 24, 48 weeks after surgery

  • KOOS

  • ICRS-CRA score

  • OAS

  • Subjects with localized full-thickness cartilage defects in the knee joint, International Cartilage Repair Society(ICRS) Grade III or IV
  • Subjects whose primary lesion site can be designated as one section of the knee joint, and the area can be determined as the main cause of clinical symptoms

You may not qualify if:

  • Patients who have autoimmune diseases (Ex. Rheumatoid arthritis)
  • When screening, Patients who underwent surgery related to cartilage defect treatment, such as microfracture, autologous chondrocyte therapy within the past 1 year (However, arthroscopy for diagnostic purposes is possible. Additionally, it is possible if hightibial osteotomy (HTO) has been performed in advance or is scheduled)
  • When screening, Patients who received intra-articular hyaluronic acid or steroid injections in the knee within 1 month
  • When screening, Patients who took oral steroid within 2 weeks
  • Patients who can't take MRI scan
  • BMI index : 30kg/m\^2 or over
  • Patients who have gout or gout history in the knee
  • Women who are pregnant or breast-feeding, or women who have a possibility of pregnancy but do not use medically accepted methods of contraception.
  • Patients with risk factor for bleeding
  • Other than above, patients who are judged by medical investigator to be considered unsuitable for this clinical trial
