Details and patient eligibility

About

The purpose of this study is to assess the safety and efficacy of implanting bead-type autologous chondrocytes (CartiLife®) obtained by culturing expanded costal chondrocytes of the patient with a chondral defect in the knee. The patients will be assessed clinically using clinical, biochemical and IKDC (International Knee Documentation Committee) outcomes preoperatively as well as 4, 8, 24 and 48 weeks postoperatively to assess the relief of symptoms and joint function.

Enrollment: 6 patients

Sex: All

Ages: 19+ years old
