Joint pain is a common ailment of aging, thanks to cartilage’s tendency to wear out. Now, researchers at Duke University have developed a new hydrogel that’s stronger and more durable than the real thing, which could make for longer lasting knee implants.
Natural cartilage plays an important role in cushioning joints, but unfortunately it doesn’t regenerate itself very well after damage by age or injury. Current treatment options are usually limited to pain medication, physical therapy, or if things progress too far, a total knee reconstruction. But if the Duke team’s new work pans out, a better option might soon be available.
Soft and flexible, hydrogels have been investigated as potential cartilage replacement materials, but most of them have been too weak to support much weight. In 2020 the Duke team created a hydrogel that had properties that were as good as natural cartilage – and now they’ve developed a version that surpasses the real thing.
