Hyaluronic acid injections into the stifle are often used for managing osteoarthritis in dogs. Giving hyaluronic acid orally would be easier, but to date we do not have enough information regarding its effects when administered by this route. For this reason, in this study we evaluated the effects of oral administration of hyaluronic acid in dogs with cranial cruciate ligament rupture after surgical resolution. Dogs were divided into two groups that received either oral hyaluronic acid or a placebo. We measured changes in several biomarkers of osteoarthritis before surgery, and at ten weeks after surgery. Results showed significant improvements in some of these biomarkers, namely synovial fluid levels of hyaluronic acid and paraoxonase-1. These changes indicate that post-op oral administration of hyaluronic acid may be effective for the management of stifle osteoarthritis in the dog.
