"Horse over at the knee" is a common term used to describe a conformation fault in horses where the knees appear to angle inward, towards the horse's midline. This condition, also sometimes referred to as knock-knees or valgus conformation, can affect a horse's movement, soundness, and overall performance. Understanding this conformation issue is crucial for horse owners, breeders, and riders alike. This article will delve into the causes, consequences, and management strategies for horses with this conformation.
What Causes a Horse to Be Over at the Knee?
Several factors contribute to a horse being over at the knee. These can include:
- Genetics: This is often the primary cause. The inheritance of specific genes predisposes some horses to this conformation fault. Careful breeding practices can help to minimize the prevalence of this trait within a bloodline.
- Nutritional Deficiencies: Inadequate nutrition, particularly deficiencies in essential minerals like calcium and phosphorus, can affect bone development and contribute to angular limb deformities.
- Injury: While less common, injuries to the developing joints during the foal's early life can lead to abnormal bone growth and result in a knock-kneed stance.
- Trauma: Significant trauma to the knee joint can alter the alignment and lead to a knock-kneed appearance.
- Rapid Growth: Rapid growth spurts in young horses can sometimes overwhelm the structural support of the legs, leading to angular limb deformities.
How does being over at the knee affect a horse's movement?
Horses over at the knee often exhibit altered gait mechanics. The inward angulation of the knees can lead to:
- Increased Strain on Joints: The abnormal alignment places extra stress on the knee, fetlock, and other joints, increasing the risk of arthritis and other degenerative conditions.
- Uneven Weight Distribution: The altered conformation can cause uneven weight distribution, potentially leading to lameness and decreased performance.
- Shorter Stride Length: The inward angulation can restrict the range of motion in the leg, resulting in a shorter, less efficient stride.
Can a horse over at the knee still be sound?
The impact of being over at the knee on soundness varies greatly. Some horses with this conformation may remain sound and perform well throughout their careers, especially if the degree of over at the knee is slight. However, more severe cases can significantly compromise soundness and lead to lameness, particularly with strenuous work.
What are the long-term consequences of a horse being over at the knee?
The long-term consequences can include:
- Osteoarthritis: The increased stress on the joints significantly increases the risk of developing osteoarthritis.
- Lameness: Chronic stress can eventually lead to lameness, impacting the horse's ability to perform its intended tasks.
- Reduced Performance: The altered gait and increased strain on joints can negatively affect performance, particularly in disciplines that demand agility and speed.
How is the condition managed?
Management strategies depend on the severity of the conformation fault and the horse's overall health and performance level. Options may include:
- Farrier Adjustments: A skilled farrier can sometimes use corrective shoeing to alleviate some of the strain on the joints.
- Veterinary Care: In severe cases, veterinary intervention, possibly including surgery, may be necessary.
- Supportive Therapies: Therapies such as physiotherapy or other forms of supportive care might improve joint function and manage discomfort.
- Adjusted Workload: Adapting the horse’s workload to reduce stress on the affected joints is crucial to prolong soundness.

Always consult with a qualified veterinarian for any concerns about your horse's health and conformation. They can accurately assess the severity of the condition and recommend appropriate management strategies.
