The answer is "C" - Osteoarthritis!
Osteoarthritis (OA) is a leading cause of lameness in horses, accounting for about 60% of lameness cases. It’s a progressive joint disease where the smooth cartilage that cushions the ends of bones gradually breaks down due to wear and tear, injury, or inflammation. As the cartilage deteriorates, the bones in the joint start to rub against each other, causing pain, swelling, and reduced mobility.
In horses, OA often starts with inflammation of the joint lining (synovitis) or the joint capsule (capsulitis), which can speed up cartilage damage. Early and effective management of this inflammation is important because it can help slow the progression of the disease and protect the joint.
Treatments for OA in horses focus on relieving pain and inflammation (symptom-modifying drugs) and, when possible, slowing or changing the course of the disease itself (disease-modifying drugs).
While OA can’t be reversed, prompt attention and ongoing care can help horses stay comfortable and active, allowing them to enjoy a better quality of life even with this chronic condition.
