In collaboration with Chinese colleagues in North Carolina, JIANG Qing at Nanjing University Medical School has developed a one-step method for cartilage repair. The technique is based on wrapping small organic molecules containing in a nano liquid holder, filled them into cartilage defects by microsurgery and apply UV irradiation for 30 seconds. This results in sustained-release of active components which after two months leads to repaired cartilage defects. Histology, morphology and biomechanics were close to natural cartilage.
