Knee Model (IMAGE) Duke University Caption A cartilage-mimicking material created by researchers at Duke University may allow surgeons to 3-D print meniscus implants or other replacement parts that are custom-shaped to each patient's anatomy. To demonstrate how it might work, the researchers used a $300 3-D printer to create custom menisci for a model of a knee.
