Innovative Biomaterial Shows Promise for Cartilage Regeneration

Northwestern University researchers develop a new material that could potentially replace knee replacement surgeries by regenerating high-quality cartilage.

The biomaterial mimics natural cartilage and successfully regenerated cartilage in sheep knee joints within six months.
If effective in humans, it could treat osteoarthritis, reducing the need for total knee replacement surgeries.
The material combines a bioactive peptide with modified hyaluronic acid to create a scaffold for tissue regeneration.
Sheep were chosen for the study due to similarities in joint mechanics and cartilage regeneration challenges with humans.
The findings were published in the Proceedings of the National Academy of Sciences.
