“Joint disorders in horses may be caused by trauma to the joint, long-term inflammation, developmental problems, or infections. … Osteoarthritis is a major cause of pain and decreased performance in horses.” Stephen B Adams (MSD Manual)
How common are joint-related problems in the performance horse population, and what impact do they have on overall soundness and athletic ability?
Exercise is necessary to maintain joint homeostasis and plays a crucial role in the physiological maturation of joints in young horses. Appropriate, controlled exercise stimulates the development of healthy cartilage, strengthens supporting soft tissues, and enhances joint lubrication, all of which are vital for long-term soundness. However, when exercise intensity, frequency, or type exceed the body’s adaptive capacity, cumulative stress and microtrauma can accelerate cartilage wear and joint degeneration.
Among equine athletes, joint disease ranks as a major cause of lameness and career limitation. 60% of equine lameness is related to osteoarthritis. Osteoarthritis (OA) frequently emerges as a lasting consequence of the physical demands placed on horses across different sports.
Maintaining healthy joints and soft tissues is therefore essential for equine athletes across all disciplines—dressage, show jumping, eventing, racing, and endurance. Racehorses experience joint injuries in up to 46% of musculoskeletal cases. Each sport imposes unique biomechanical stresses that can lead to tendon and ligament injuries, cartilage degeneration, and arthritis.
The good news is, that although pre-osteoarthritis can occur without clinical signs in horse athletes, there are various ways in which the maturation and evolution of equine joints can be monitored to avoid the occurrence of injuries. And with an integrative approach—combining preventive veterinary care, natural joint supplements, balanced nutrition, and physical therapy—horses can maintain flexibility, strength, and long-term mobility throughout their athletic careers, and well into their golden years.
Understanding how Equine Sports Stress Joints
Different equine disciplines predispose horses to specific injuries:
- Dressage: Repetitive collection and lateral movements strain the deep digital flexor tendon (DDFT), suspensory ligaments, and hocks. Chronic microtears can accelerate osteoarthritis. Both performance levels especially increase the risk of injury to the hind limb suspensory ligament and proximal deep digital flexor tendon.
- Show Jumping: Landings from high jumps stress fetlock joints and tendons, often causing suspensory ligament injuries, joint inflammation, and bone bruising. Most common injuries associated with show jumping are to the suspensory ligament, followed by the distal deep digital flexor tendon and forelimb superficial digital flexor tendon.
- Eventing: Combines dressage, cross-country, and jumping; horses are prone to tendonitis, soft tissue injuries, and cumulative joint stress. Elite Eventing had a very high risk of injury to the forelimb superficial digital flexor tendon, and low risk of tarsal injury.
- Racing: High-speed gallops cause stress fractures, cartilage microdamage, and synovitis, with racehorses experiencing joint injuries in up to 46% of musculoskeletal cases (McIlwraith, 2010). Flat racing holds a high risk of injury to the carpus, whilst National Hunt racing increases the risk of injury to the forelimb superficial digital flexor tendon.
Pathophysiology of Injury:
Acute injuries, such as tendon tears, ligament strains, and sprains, trigger inflammation and cellular damage. If untreated, this can cascade into chronic joint inflammation, cartilage breakdown, and ultimately osteoarthritis.
The physiology behind this involves:
- Mechanical overload: High-impact landings, tight turns, or repetitive motion compress joint surfaces and degrade cartilage.
- Inflammatory cascade: Injured tissue releases pro-inflammatory cytokines, accelerating cartilage breakdown and synovial inflammation.
- Compensatory strain: Horses often shift weight to protect an injured limb, stressing adjacent joints and tissues.
Acute vs. Chronic Inflammation: Protecting Joints from an Early Age
Equine athletes are particularly susceptible to joint stress due to the high demands of their disciplines. Acute inflammation occurs immediately after an injury, such as a tendon strain, ligament sprain, or cartilage microtrauma, as the body mobilizes immune cells to remove damaged tissue and initiate repair. This process is essential for normal healing. However, when stress is repetitive, training is excessive, or healing is incomplete, the horse may develop chronic inflammation. Chronic inflammation continuously releases enzymes and inflammatory mediators that break down cartilage, weaken tendons and ligaments, and accelerate the onset of osteoarthritis.
Protecting joints from a young age and throughout the horse’s life is critical. Early intervention with natural supplements like Glucosamine, MSM, Curcumin, Boswellia Serrata, Hydrolyzed collagen, Spirulina, and Omega-3 fatty acids provide a multi-layered defense by
- Modulating inflammation to prevent excessive cartilage degradation.
- Promoting collagen and cartilage synthesis, strengthening tendons, ligaments, and joint structures.
- Reducing oxidative stress, protecting soft tissues during high-performance activity and recovery.
By incorporating these supplements from the onset of training, horse owners can establish resilient joint and soft tissue health, reducing the risk of chronic inflammation, degenerative joint disease, and early retirement. Lifelong joint support ensures that equine athletes maintain mobility, comfort, and peak performance throughout their careers.

Pro-Active Equine Joint Care with natural extracts in researched concentrations, like these available in Untamed Hip & Joint – Equine, can significantly enhance resilience to injury, support cartilage and tendon health, and promote long-term mobility.
Not only do natural extracts provide remarkable equine joint support;
with their multi-functional properties, these ingredients further provide profound systemic benefits:
Curcumin: Regulates Th1/Th2 cytokine balance, lowering the risk of autoimmune-mediated inflammation and allergies (Aggarwal et al., 2006). It also enhances liver detoxification and provides antimicrobial protection against bacteria, fungi, and viruses, supporting the horse’s immune resilience.
Spirulina: Promotes muscle hypertrophy, enhances power output, and improves endurance capacity. It enhances antibody response and protects against immune overactivity which may lead to rheumatoid arthritis. (Belay et al., 1993). It functions as a prebiotic, supporting gut microbiota balance, improving nutrient absorption, and aiding in detoxification of heavy metals such as lead, cadmium, mercury, and arsenic. Its antioxidants support liver and cardiovascular health, improve insulin sensitivity, and protect against systemic degenerative inflammation, allergies, and skin conditions.
Boswellia: Beyond its joint-specific benefits, Boswellia’s immunomodulatory and antioxidant effects protect against systemic inflammation, oxidative stress, and degenerative diseases affecting the nervous, digestive, and cardiovascular systems (Ammon, 2010).
Synergy of Nutrients for Performance and Longevity
Curcumin, Boswellia, Spirulina, and Glucosamine work synergistically to effectively reduce inflammation, enhance antioxidant capacity, and stimulate regeneration of cartilage, ligaments, and muscle tissue. Together, these natural extracts further provide broad-spectrum systemic support—promoting immune balance, detoxification, cardiovascular protection, digestive health, cognitive resilience, stamina and endurance, and improved physical conditioning.
Horses receiving early and consistent joint support benefit from improved endurance, faster recovery, and long-term joint integrity, ensuring prolonged athletic careers and overall vitality.
Allopathic Interventions for Acute Injury
- NSAIDs – Reduce pain & inflammation; long-term use may cause gastric/kidney issues (McCann et al., 2012)
- Corticosteroids – Powerful anti-inflammatory; repeated use may accelerate cartilage damage (McIlwraith, 2010)
- Hyaluronic Acid (HA) – Lubricates joints; effective but temporary
- IRAP, PRP, Stem Cells – Regenerative therapy; promising but costly
💡 Takeaway: These treatments may play a valuable role in managing acute pain and inflammation, helping horses stay comfortable and active. For optimal long-term mobility and performance, however, it’s vital to address the underlying causes of joint dysfunction and support overall organ health to complement medical treatment. By integrating natural joint support—such as targeted nutrition, herbal anti-inflammatories, and joint-nourishing supplements owners can also enhance the body’s natural healing processes, protect vital organs, and promote sustainable soundness.
Integrating Physical & Manual Therapy in Recovery
In addition to medical and nutritional support, physical and manual therapies play a pivotal role in the rehabilitation of soft tissue and joint injuries in equine athletes. Techniques such as therapeutic ultrasound, shockwave therapy, cold and heat applications, low-level laser (photo biomodulation), and pulsed electromagnetic field therapy (PEMF) are scientifically shown to enhance circulation, reduce inflammation, and accelerate collagen and tendon fibre repair. Massage, chiropractic adjustments, myofascial release, and controlled exercise programs help maintain flexibility, prevent compensatory strain, and restore proper biomechanics during recovery. These therapies are most effective when implemented progressively—beginning with cryotherapy and rest during the acute phase, advancing to mobilization, hydrotherapy, and strengthening work as healing continues. A structured, individualized rehabilitation plan guided by veterinarians and physiotherapists ensures complete healing and minimizes re-injury risk, allowing horses to return to peak performance safely.
Manual physio therapy on thoracic limbs. Passive stretching (A, B, C) with possibility of joint mobilization (B, C); and active stretching of neck (D, E).
Integrating natural supplements, allopathic treatments, and physical therapy ensures optimal recovery, joint longevity, and sustained performance.
In practice, this means taking a multi-layered, proactive approach to joint health:
- Natural Supplements: provide the building blocks for cartilage, tendons, and ligaments. They modulate inflammation, support tissue repair, reduce oxidative stress, and strengthen the musculoskeletal system. In researched concentrations natural extracts exhibit powerful joint protection and healing properties, essential for optimal treatment of both acute and chronic pain and inflammation. Early and consistent supplementation helps the horse resist the cumulative wear and tear caused by high-intensity training, competition, or repetitive movement patterns specific to each discipline.
- Allopathic Treatments: In cases of acute injury or flare-ups, veterinary interventions such as non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroid injections, and regenerative therapies (e.g., platelet-rich plasma [PRP] or stem cell therapy) are highly effective in controlling inflammation, reducing pain, and assisting tissue repair. These interventions can prevent minor injuries from progressing to chronic conditions or permanent joint damage. ***It is crucial that the horse does not resume regular training while recovering, even when under pain-relief medication. Pain-masking medication or treatments can allow the horse to overexert injured tissues, bypassing the natural temporary functional limitations that are necessary for proper healing. Integrating these treatments with sufficient rest, physiotherapy, controlled exercise, and adjunctive natural supplements maximizes recovery outcomes and long-term joint health.
- Physical Therapy: Targeted rehabilitation strategies promote proper tissue remodelling, maintain joint range of motion, and prevent compensatory injuries. This ensures that the horse returns to training safely, maintains muscle balance, and minimizes long-term biomechanical stress on joints.
Combined Approach: When these three strategies are used together, the horse benefits from enhanced recovery after injury, slowed progression of degenerative joint changes, and a higher capacity for sustained performance. Essentially, this integrative model doesn’t just treat symptoms—it addresses the root causes of joint degeneration, supports lifelong mobility, and maximizes athletic longevity.
