Results
No adverse events were recorded, and self-assessed clinical scores for pain, symptoms, activities of daily living, sports activity, and quality of life were significantly improved at 24 months after surgery. Secure defect filling was confirmed by second-look arthroscopy and magnetic resonance imaging in all cases. Histology of biopsy specimens indicated repair tissue approaching the composition and structure of hyaline cartilage.

Baseline Characteristics
Articular cartilage has limited healing capacity, owing in part to poor vascularity and innervation. Once injured, it cannot be repaired, typically leading to high risk for developing osteoarthritis. Thus, cell-based and/or tissue-engineered approaches have been investigated; however, no approach has yet achieved safety and regenerative repair capacity via a simple implantation procedure.
Participant flow
An observational first-in-human study limited to 5 cases was approved by the Ministry of Health, Labor, and Welfare of Japan and performed at Osaka University Hospital between April 2013 and May 2016. Five patients aged 20 to 60 years were enrolled with isolated full-thickness cartilage defects of the knee (<5 cm2, International Cartilage Regeneration & Joint Preservation Society [ICRS] grade III or IV).
