3-D-Printable Implants May Ease Damaged Knees

3-D-Printable Implants May Ease Damaged Knees

Researchers at Duke University have developed cartilage mimicking material. The development will allow doctors to 3-D print replacement knee parts for patients.

Key takeaways:

– The material developed is called hydrogel and mimics human cartilage in strength and elasticity.

– The hydrogel can best be used to replace the menisci in the knee that is subject to wear and tear over a lifetime.

– The ability to 3-D print the hydrogel provides a simple and inexpensive way of making knee replacements that are custom-fit to the patient’s anatomy.

These custom implants are based on virtual 3-D models of a patient’s anatomy, which can be obtained from computer tomography (CT) or magnetic resonance imaging (MRI) scans.
