Joints

We hear a lot about artificial hips and knees, but finger joints? They do exist, but their fit and functionality is limited. Germany's Fraunhofer research group aims to change that, with artificial finger joints that are 3D-printed for each patient.

New data suggests long-term use of non-steroidal anti-inflammatory drugs, such as naproxen or ibuprofen, can be associated with hastened progression of osteoarthritis symptoms. The researchers are cautious to stress the link is still observational.

The rise of drug-resistant bacteria calls for new approaches to how doctors protect against bone infection after joint replacements, and a potent new form of bone cement is poised to take up the fight.

Joint pain is a common ailment of aging, thanks to cartilage’s tendency to wear out. 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.

Scientists have developed an injectable gel that can prevent a form of injury-triggered osteoarthritis taking hold, by allowing for sustained delivery of drugs in the damaged joints to keep inflammation at bay.

Scientists have demonstrated how engineered nasal tissue can not only act as structural reinforcement for troublesome joints, but also how its unique properties can counter inflammation in severe osteoarthritis.

Researchers at Washington University have tested an experimental new treatment for rheumatoid arthritis in mice. The team implanted stem cells that have been reprogrammed to secrete anti-inflammatory drugs only when they sense inflammation.

Taking inspiration from some of the unique attributes of dragonfly wings, scientists at Germany’s Kiel University have developed a new type of splint for injured joints that offers support in all the right places.

Researchers at Pennsylvania State University studying an approved anti-depressant drug have found it can interfere in the chain of events leading to osteoarthritis, halting its progress and even promoting the regeneration of cartilage.

Human knees are notoriously vulnerable to injury or wearing out with age, often culminating in the need for surgery. Now researchers have created new hybrid bioinks that can be used to 3D print structures to replace damaged cartilage in the knee.

Like most machines, the human body tends to wear out faster at the points of articulation, where decades of stress are focused. Now, researchers at Stanford have found a way to induce cartilage tissue to regenerate in joints by tweaking the stem cells there.

Osteoarthritis is one of the most common ailments of an aging population. Now, researchers at the Salk Institute have found that a combination of two experimental drugs appears to reverse the symptoms of the disorder in rats and in human cells.
