5. Received an injection in the target knee within two months before enrollment in this study
6. Pregnant or breastfeeding female
7. With another joint disease apart from degenerative arthritis (e.g., systemic rheumatic inflammatory disease associated with the knee or chondrocalcinosis, hemachromatosis, inflammatory arthritis, necrosis of the trochanter, Paget's disease adjacent to a joint in the femur or tibia, ochronosis, hemophilic arthropathy, infectious arthritis, Charcot's disease in the knee joint, villonodular synovitis, and synovial chondromas)
8. With a current infectious disease, including HIV or hepatitis

9. Has any of the following clinically significant diseases:

   • heart disease [e.g., myocardial infarction, arrhythmia, other serious heart disease, coronary artery bypass graft (CABG)]
   • kidney disease (e.g., chronic renal failure, glomerulonephritis)
   • liver disease (e.g., liver cirrhosis, fatty liver, acute or chronic liver disease)
   • endocrine disease (e.g., hyperthyroidism, hypothyroidism, thyroiditis, diabetes insipidus, Cushing's disease)
   • insulin-dependent diabetes mellitus
   • medical history of or current malignant tumor

   • In particular, the tumors that TissueGene-C may aggravate can be screened using the following tests:

     • Leukemia: White Blood Cell level in the hematology
     • Osteochondroma, Chondromas, Chondroblastoma, Chondromyxoid fibroma, Chondrosarcoma : Alkaline phosphatase level in the hematology
10. Participated in another clinical trial (using the investigational drug or a medical device) within 30 days before enrollment in this study
