Surgeons at The Ohio State University Wexner Medical Center repair a man`s knee using cartilage that was grown in a laboratory. Doctors extracted cells from a healthy part of the patient`s leg weeks before, used those cells to grow new cartilage, then re-implanted the new cartilage into his injured knee. If it proves successful, the experimental procedure could provide new options for the quarter of a million Americans each year who require surgery on damaged knee cartilage.
