Capped knee refers to a condition affecting horses, specifically their knee joint, and it is characterized by the accumulation of excessive fluid and inflammation in the area. It is a condition commonly observed in horses involved in rigorous physical activities, such as racing, jumping, or prolonged exercise. Despite its name, the condition can also affect other joints in the horse's body, such as the hock or elbow.
Capped knee is typically caused by repeated trauma or the horse frequently striking its knee against hard surfaces. This repetitive impact disrupts the delicate structures within the joint, leading to increased fluid production and subsequent swelling. The condition is often accompanied by pain, heat, and tenderness around the affected area.
When the knee joint is impacted or injured, the horse's body has an immune response that increases fluid production in an attempt to protect and heal the damaged tissues. However, if this process becomes excessive or the trauma persists, it can result in the accumulation of fluid, forming the characteristic "cap" or swelling on the knee.
Treatment for capped knee involves reducing inflammation and addressing the underlying cause. It may include resting the horse, applying cold therapy, administering anti-inflammatory medications, and potentially draining accumulated fluid if it becomes problematic. In severe cases, surgical intervention may be necessary to repair any damaged structures within the joint.
Capped knee can significantly impact a horse's performance and welfare if left untreated. Hence, prompt veterinary attention and appropriate management are crucial to minimize discomfort and prevent long-term complications.
