Osteoarthritis in horses: what real veterinary cases show
Osteoarthritis in horses is a degenerative joint disease that affects the cartilage, leading to pain and reduced mobility. It is commonly caused by wear and tear on the joints, often exacerbated by factors such as age, injury, or intense physical activity. This condition is prevalent in performance horses but can affect any horse.
Owners typically notice lameness, stiffness, or reluctance to move as initial signs. Early detection is crucial as it can help manage the condition more effectively, potentially slowing its progression and improving the horse's quality of life.
What vets typically check for
- Perform a thorough physical examination and assess the horse's gait.
- Use diagnostic imaging such as X-rays to evaluate joint changes.
- Consider ultrasound or MRI for a more detailed view of soft tissues.
- Conduct joint fluid analysis to rule out infections or other conditions.
- Implement a treatment plan involving pain management, joint supplements, and controlled exercise.

- Bilateral hindlimb superficial digital flexor tendinopathy in a sports horse.
Journal of equine veterinary science · 2026 · United Kingdom
A 16-year-old Irish sports horse gelding was brought in because he had swelling in both hind legs and was limping badly after competing in a cross-country event. The veterinarian suspected he had injured a tendon in his legs, which was confirmed by an ultrasound that showed significant damage to the tendons. To treat this, the vet injected a special concentrate made from the ho
- Western performance horses with fetlock lameness demonstrate radiographic evidence of chronic exercise remodelling.
Equine veterinary journal · 2026 · United States
A group of western performance horses with fetlock lameness showed signs of chronic changes in their fetlock joints when examined through X-rays. Most of the horses had issues like bone thickening and cysts, which were linked to more severe lameness. However, the overall severity of the X-ray findings didn't directly match how lame the horses appeared. This suggests that while
- High-field magnetic resonance imaging enables diagnosis of central tarsal bone fractures in performance horses with lameness localized to the proximal metatarsus and tarsus.
Journal of the American Veterinary Medical Association · 2026
A group of eight performance horses, including Quarter Horses and a Thoroughbred, were brought in for lameness in the back legs, which had been ongoing for some time. High-field MRI revealed fractures in the central tarsal bone, a condition that can be hard to diagnose with regular X-rays. The horses showed varying degrees of lameness, and the fractures were often accompanied b
- Standing repair of long frontal plane fractures of the proximal phalanx in UK Thoroughbred racehorses: A retrospective analysis of 13 fractures.
Equine veterinary journal · 2026 · United Kingdom
A group of UK Thoroughbred racehorses with long frontal plane fractures in their hind legs underwent a special surgery using standing lag screws to fix the fractures. Out of 11 horses treated, 73% returned to racing after an average of about a year, although one horse had to have the screws removed due to a complication. The surgery took about 30 minutes on average, and the res
- Four-step tenoscopic technique to resect a torn proximal manica flexoria while sparing the mesotendons of the deep digital flexor tendon in 30 horses.
Veterinary surgery : VS · 2026 · Germany
A group of 30 horses with torn proximal manica flexoria (a tendon structure) underwent a specialized surgery to remove the damaged tissue while protecting surrounding tendons. Most of the injuries were found in the hindlimbs, and the horses were able to return to their previous level of activity after the procedure. The surgery was successful in all cases, with many horses, inc
- Ultrasound-guided, minimally invasive, biceps brachii tenotomy in a standing horse.
Veterinary surgery : VS · 2026 · United States
A 17-year-old Tennessee Walking Horse was suffering from severe lameness in the left shoulder due to tendon and joint issues. After trying conservative treatments without success, the veterinarian performed a minimally invasive surgery to cut the affected tendon while the horse was standing. Following the surgery, the horse showed significant improvement in lameness and continu
