Artificial cartilage senses arthritis pain, then morphs to block it | A squishy cartilage-like material can be loaded up with either long-term or short-term pain killers that are released when the material senses chemical stress from arthritis.
A squishy cartilage-like material has been developed by researchers at the University of Cambridge. It can be loaded up with either long-term or short-term pain killers that are released when the material senses chemical stress from arthritis.
One of the major issues with our joints as we age is that once the cartilage that cushions them degrades, it never grows back because it lacks a blood and nerve supply. The researchers say that while the material now needs extensive testing in in vitro models – which they plan to do – it holds the potential to dramatically improve not only arthritis symptoms but other conditions in the body that could benefit from targeted drug delivery. “It’s a highly flexible approach, so we could in theory incorporate both fast-acting and slow-acting drugs, and have a single treatment that lasts for days, weeks or even months,” said O’Neill.
