Role of subchondral bone remodelling in collapse of the articular surface of <scp>T</scp> horoughbred racehorses with palmar osteochondral disease

Abstract

Articular surface collapse is common in cases of palmar osteochondral disease and is likely to be a sequel to fatigue injury of subchondral bone. Focal subchondral bone resorption appears to contribute to collapse of the calcified cartilage and is potentiated by a reduced-intensity exercise regimen.
