Understanding Arthritis and Arthrosis in Horses: A Comprehensive Guide


As caring stewards of our equine companions, it's crucial to be well-informed about common health conditions they may face. Two prevalent musculoskeletal issues in horses are arthritis and arthrosis. In this guide, we'll delve into the differences, causes, symptoms, and management strategies for these conditions.

Arthritis vs. Arthrosis: What's the Difference?

While both terms are often used interchangeably, they refer to distinct conditions. Arthritis involves inflammation of the joints, while arthrosis is characterized by the degeneration of joint cartilage. Both conditions can lead to discomfort, lameness, and decreased mobility in horses.

Causes and Risk Factors


  • Infection: Bacterial or viral infections can trigger joint inflammation.
  • Autoimmune Disorders: Conditions where the immune system mistakenly attacks the joints.
  • Trauma: Joint injuries or fractures can contribute to arthritis.


  • Aging: Wear and tear on joints over time.
  • Genetics: Some horses may be predisposed to cartilage degeneration.
  • Overuse or Improper Use: Excessive strain on joints due to activities like intense training or incorrect riding.

Recognizing Symptoms

Both arthritis and arthrosis can exhibit similar signs:

  • Lameness: Noticeable unevenness in gait.
  • Stiffness: Difficulty in moving, especially after periods of rest.
  • Swelling: Visible swelling around affected joints.
  • Decreased Performance: Reluctance or inability to perform usual activities.

Management and Treatment

Veterinary Care:

  • Diagnosis: Accurate diagnosis through imaging techniques like X-rays or ultrasounds.
  • Medication: Anti-inflammatory drugs or pain relievers prescribed by a veterinarian.

Lifestyle and Care Adjustments:

  • Balanced Diet: Nutritional support for joint health.
  • Appropriate Exercise: Regular, moderate exercise to maintain joint function.
  • Comfortable Living Conditions: Adequate shelter and comfortable bedding.

Alternative Therapies:

  • Physical Therapy: Gentle exercises to improve joint flexibility.
  • Joint Supplements: Glucosamine and chondroitin supplements to support cartilage.


Understanding the nuances of arthritis and arthrosis empowers horse owners to take proactive measures for their equine friends. Regular veterinary check-ups, a keen eye for symptoms, and thoughtful management can significantly enhance the quality of life for horses dealing with these conditions. As responsible caretakers, let's ensure our horses enjoy comfort and mobility throughout their lives.
