ABSTRACT
Bowe EA, Henson FMD, Caddick
J, Jeffcott LB, Davies ME. Response of equine articular
cartilage to a single impact load. Onl J Vet Res., 8: 33-41,
2004. The aim of this study was to investigate the damage caused to equine
articular cartilage by a single impact load applied using a simple drop tower
device. An impact load (500g) caused histological changes including
fissure formation, disruption of the articular surface and loss of proteoglycan
content, which were more marked at a drop height of 10cm compared to
2.5cm. The damage caused by a single impact load from a height of 2.5cm
was comparable to that previously reported in exercised horses and in clinical
cases of degenerative joint disease. These results indicate that the method of
single impact load in cartilage may have potential in the in vitro investigation of equine
cartilage damage.
KEY WORDS: Equine, cartilage, load, osteoarthritis.
