The findings of this research study may help explain why cartilage breaks down with ageing or arthritis.

Research paper identifies the secret life of collagen

12 September 2017

Dr Gupta and Prof Knight have just published exciting results which cast light on how cartilage is able to withstand the demanding mechanical environment of the joint and may eventually help to explain why cartilage breaks down with ageing or arthritis. Collagen changes its crystallinity in response to physical forces, ... [more]
