Interventions

s injectable articular cartilage (EB-iAC) is a biologically similar tissue material developed through the use of allogenic bone marrow derived mesenchymal stromal cells (BM-MSCs). The cells are proces
s natural physiological development by inducing BM-MSCs to form cartilage precursor tissue through mesenchymal condensation to generate drug substance EB-CMB. Upon implantation, EB-iAC is anticipated

Exclusion criteria

Exclusion criteria: 1. Lesions on the opposing surface that are classified as ICRS grade 4. 2. Lesions on the opposing surface of the patella that are classified as ICRS grade 4 if a trochlear defect is being treated. 3. Any existing prosthetic implants in the index joint. 4. History of surgery in the index joint within 6 months prior to screening. 5. Has osteoarthritis of Kellgren-Lawrence Grade greater than or equal to 3 as diagnosed on standing radiographs in the index joint. 6.
