This study is a double-blind, randomized, controlled study with two arms to evaluate JointStem as a treatment for subjects with osteoarthritis. Following a 2-week screening period, approximately 45 subjects will be randomly assigned into one of the following two arms in a 2:1 ratio (2 JointStem : 1 positive control). After the last subject completes 6-month visit (Visit 6) and the data management team confirms all data have no issue, the database will be locked and the blinding will be open for the statistical analysis. Subjects will then be scheduled for 9-month and 12-month follow-up visits (Visits 7 and 8).

Primary Outcome Measures:
  • Change from Baseline on MRI scan results [ Time Frame: Baseline and 6 months ]
    Quantitative analysis (cartilage volume, cartilage articular surface area, cartilage thickness, subchondral bone surface curvature)

Secondary Outcome Measures:
  • Change from baseline on WOMAC (Western Ontario and McMaster Universities Arthritis Index) score [ Time Frame: Baseline, 1 month, 3 months and 6 months ]
  • Change from baseline on VAS (Visual Analog Scale) [ Time Frame: Baseline, 1 month, 3 months and 6 months ]
    Subjects mark on the scale depending feeling the itching rates (0 mm for no pain and 100mm for the worst pain ever)

  • Change from baseline on KOOS (Knee Injury & Osteoarthritis Outcome Score) [ Time Frame: Baseline, 1 month, 3 months and 6 months ]
  • Change from baseline on Lysholm Knee Scoring Scale [ Time Frame: Baseline, 1 month, 3 months and 6 months ]
  • Change from baseline on IKDC (International Knee Documentation Committee [ Time Frame: Baseline, 1 month, 3 months and 6 months ]
    Containing 7 symptom, 10 sports activities and 2 function questions.

  • Change from baseline on RAND-36 Score [ Time Frame: Baseline, 3 months and 6 months ]
    Healthy survey with 36 quality-of-life questions

  • Incidence of adverse events and laboratory abnormalities [ Time Frame: Baseline, 1 month, 3 months and 6 months ]
