Biomechanical properties of third carpal articular cartilage in exercised and nonexercised horses.
Abstract: The relevance of site and exercise on the biomechanical properties of the articular cartilage from the equine third carpal bone were assessed by creep indentation testing. Six horses were exercised for 30 minutes three times weekly. Another six horses were housed in box stalls and were not exercised. At the conclusion of the study, one third carpal bone from each horse was harvested and the KLM biphasic material properties of cartilage were determined at 12 sites. There was a significant (p < 0.01) effect of site but not exercise on the cartilage aggregate modulus, which was significantly lower for sites on the dorsal aspect of the radial facet and for all sites on the intermediate facet as compared with sites on the palmar aspect of the radial facet of the third carpal bone. Exercise significantly increased the permeability constant at all sites when compared with the nonexercised group, but there was no difference between sites within groups. Exercise also significantly increased Poisson's ratio, but only at sites located on the palmar aspect of the radial facet. In general, both site and exercise influence the biomechanical behavior of third carpal articular cartilage. Inherent differences in cartilage biomechanical properties within a joint correlate with the location specificity of cartilaginous lesions in the equine midcarpal joint.

This is a study investigating the effects of exercise on the biomechanical properties of articular cartilage in horses’ third carpal bones. The research found that both location and exercise had significant effects on the cartilage’s properties.
Methods
- The study involved 12 horses, which were divided into two equal groups. One group was exercised for 30 minutes three times a week, while the other group was kept in stall boxes and not exercised.
- At the end of the study, one third carpal bone was harvested from each horse. The cartilage from 12 different sites on these bones was then collected and its biomechanical properties measured.
- These properties were determined through creep indentation testing and involved examining the aggregate modulus, permeability constant, and Poisson’s ratio of the cartilage. This allowed the researchers to quantify how the cartilage responded to forces and moved fluid around.
Findings
- Site had a significant effect on the cartilage’s aggregate modulus. This is a metric that reflects how rigid or flexible the material is. The sites on the dorsal aspect of the radial facet and all sites on the intermediate facet had a lower aggregate modulus compared to sites on the palmar aspect of the radial facet of the third carpal bone.
- Exercise increased the permeability constant at all sites. This means the cartilage of exercised horses allowed more fluid to pass through, which could impact how it responds to forces.
- Exercise also increased Poisson’s ratio, but only at sites located on the palmar aspect of the radial facet. Poisson’s ratio measures how much a material can be compressed along one axis relative to its expansion along the other axes.
Conclusions
- Overall, the study illustrates that both site and exercise influence the biomechanical behavior of the third carpal articular cartilage.
- This understanding can be useful for understanding how different areas of a horse’s joints respond to exercise and rest and may be linked to why cartilaginous lesions in the equine midcarpal joint occur more regularly in certain areas.
