The new material is strong enough to work in knees

 Need some cartilage? There’s a technology for that.

Knee surgery is a frequently-performed procedure across the country. Why? Well, the knees are at work for most of your waking hours, and the same activity that keeps you physically fit can also lead to wear and tear on them. If you’ve ever needed to have work done on the joint itself, you may be aware of the difficulties of coming up with a lasting replacement: until recently, there wasn’t a replacement durable enough for the cartilage in a human knee.

That might no longer be the case, however. At Science Alert, David Nield has the news that a group of researchers, some affiliated with Duke University, have made a breakthrough in replacing cartilage. They’ve come up with a hydrogel that compares favorably to the material currently used for knee replacement surgery:

Rate of MRI and CT/PET scans ordered or provided have tripled from 1996 to 2007

A boom in medical technology over the past decade or two has led to a surge in certain medical tests and increased prescription drug use, say authors of a report that provides a snapshot of Americans’ health today.Imaging, assisted reproductive technologies, prescription drugs and knee replacements have all seen a dramatic rise since the early ’90s, says Amy Bernstein, the report’s lead author, a health scientist for the National Center for Health Statistics. The center, part of the Centers for Disease Control and Prevention, released the 33rd annual Report on the Nation’s Health Wednesday. It includes a special section on health technology.
