Neutron and light scattering, along with atomic force microscopy and quartz crystal microbalance, illuminate a mechanism explaining the ‘vicious circle’ of osteoarthritis.

The exact mechanism of cartilage breakdown in osteoarthritis is unknown, but damage from mechanical stress with insufficient self-repair is believed to be the main culprit...
