Bella, a 16-year-old American Quarter Horse mare, has historically suffered from chronic hind limb issues. She was previously diagnosed with bilateral osteoarthritis of the lower tarsal joints (hock), but intra-articular medication had failed to significantly improve her lameness on the right hind. Bella had been ridden by two small children for the past three years and is an integral part of their family. Due to the severity of this lameness, however, she could no longer be ridden. Committed to improving Bella’s condition, her family brought her to the UC Davis veterinary hospital.
