Mechanically adjustable and degradable scaffolds for the treatment of articular cartilage defects

, 2014
Articular cartilage (AC) has long been known as the tissue that “once destroyed, is not repaired”. Damage to the AC may impair joint function, leading to osteoarthritis, joint destruction, and ultimately, joint replacement.
