A Randomized Comparison of NeoCart to Microfracture for the Repair of Articular Cartilage Injuries in the Knee

Principal Investigator

Dennis Crawford

Study Purpose

NeoCart is a new biological tissue implant designed to repair damaged articular cartilage of the knee in patients without osteoarthritis. NeoCart is produced from a small amount of your own healthy articular cartilage. The purpose of this study is to compare the safety and efficacy of NeoCart and standard Microfracture surgical techniques for the treatment of articular cartilage injury. Participants are randomly assigned to either NeoCart (2/3 chance) or Microfracture (1/3 chance) treatment groups. Evaluations include questionnaires, physical evaluations, laboratory tests, X rays, and MRI.

Medical Condition(s)

Articular cartilage damage in patients without osteoarthritis.
