Intrinsic mechanical properties of osteophytes have been compared with
those of normal articular cartilage by obtaining force-indentation cu
rves. The cartilage of the osteophyte ions found to be thinner than ar
ticular cartilage. The mean stiffness of osteophytes was 272.8 (+/-78.
8) N/mm and the mean stiffness of articular cartilage irons 1412 (+/-9
