Arthritis / Osteoarthritis
Arthritis is inflammation and disease affecting a joint. Osteoarthritis (OA), sometimes called degenerative joint disease, is the most common form in horses and involves progressive changes within the whole joint.
Osteoarthritis is particularly common in older horses, but it is not simply a condition of old age. It can occur in horses of any age and may be associated with previous injury, repeated loading, joint instability, conformation, intensive work or other joint disease.
Although osteoarthritis cannot usually be reversed once established, appropriate veterinary treatment, management, exercise and nutritional support can often help horses remain comfortable and active for many years.
What happens in an osteoarthritic joint?
A healthy joint allows the ends of two bones to move smoothly against one another. The bone surfaces are covered by articular cartilage, while synovial fluid within the joint provides lubrication and contributes to the nutrition of the cartilage.
The joint is a living system involving cartilage, bone, synovial membrane, joint capsule, ligaments and surrounding soft tissues.
With osteoarthritis, this system becomes disrupted.
Inflammation within the joint can alter the quality of the synovial fluid and contribute to deterioration of the articular cartilage. Changes may also occur in the bone beneath the cartilage and around the margins of the joint.
Over time, the joint may become painful, stiff and less able to move normally.
Osteoarthritis is therefore more than simply the joint being "worn out". Inflammation and altered joint biology are important parts of the disease process.
Which joints can be affected?
Osteoarthritis can develop in almost any synovial joint.
Common sites include:
- hocks
- fetlocks
- knees
- coffin joints
- pastern joints
- stifles
- joints within the neck and back.
Some horses have changes in only one joint, while others — particularly older horses — may have several affected areas.
The effect on the horse depends not only upon the severity of the disease but also upon which joint is affected and what the horse is being asked to do.
What might an owner notice?
Signs can vary considerably.
An owner may notice:
- stiffness, particularly when first moving
- stiffness after standing for a prolonged period
- reluctance to move forward freely
- reduced willingness to work
- changes in performance
- difficulty with particular movements or transitions
- reluctance on circles or particular surfaces
- difficulty getting up or lying down
- joint swelling or thickening
- heat around an affected joint
- an altered gait or lameness.
Some horses appear stiff initially but move more comfortably after gentle exercise — often described as "warming out of it."
This should not be assumed to mean that there is no underlying problem. Recurrent stiffness or changes in movement deserve investigation.
Lameness may be subtle
Osteoarthritis does not always produce an obvious head-nodding lameness.
A horse may instead alter the timing, loading and movement of its limbs to reduce discomfort. To the observer this can make the movement appear shorter, choppier, uneven or less flowing.
These subtle adaptations may be particularly noticeable during turns, circles, transitions or when moving on different surfaces.
Changes that are repeatedly attributed to the horse "getting older" may therefore warrant closer investigation.
How is osteoarthritis diagnosed?
If arthritis or osteoarthritis is suspected, veterinary assessment is important.
Diagnosis may involve a combination of:
- clinical examination
- assessment of the horse standing and moving
- palpation and manipulation of the limbs and joints
- flexion tests where appropriate
- diagnostic nerve or joint blocks
- X-rays
- ultrasound
- other diagnostic imaging where required.
No single test tells the whole story.
Radiographic changes do not always correspond directly with the amount of discomfort a horse experiences. Some horses have significant changes on X-ray with relatively little clinical lameness, while others can be painful before dramatic radiographic changes are visible.
The horse and its clinical signs, rather than an X-ray alone, therefore need to be considered.
Can osteoarthritis be cured?
Established osteoarthritis is generally considered a long-term condition that is managed rather than cured.
Management aims to:
- reduce pain and inflammation
- maintain useful joint movement
- preserve muscle strength
- control bodyweight
- maintain appropriate activity
- reduce unnecessary joint stress
- support the horse's quality of life.
Treatment needs to be tailored to the individual horse and the joint involved.
Veterinary treatment
Depending upon the individual case, veterinary treatment may include pain-relieving and anti-inflammatory medication, joint medication or other therapies.
Your veterinary surgeon may also recommend changes to exercise, rehabilitation, shoeing or trimming, bodyweight management and the horse's workload.
Treatment options continue to develop, and the most appropriate approach depends upon the affected joint, severity of disease, intended use of the horse and other health considerations.
Movement matters
It can be tempting to rest a horse with arthritis for long periods, but complete inactivity is not necessarily beneficial.
For many horses with established osteoarthritis, regular controlled movement can be an important part of management.
Movement helps maintain:
- joint mobility
- muscle strength
- coordination
- circulation
- general fitness.
Long periods standing still may make some arthritic horses noticeably stiffer.
The amount and type of exercise must, however, be appropriate for the individual horse. A horse experiencing an acute painful episode or significant lameness may require a very different approach.
Where there is uncertainty, exercise should be discussed with the treating veterinary surgeon.
Turnout and daily management
Where appropriate for the individual horse, regular turnout can encourage gentle natural movement.
Management may also include:
- avoiding unnecessarily long periods of confinement
- providing comfortable footing
- avoiding persistently deep or slippery surfaces
- allowing adequate warm-up before harder work
- maintaining consistent rather than highly irregular exercise
- providing suitable bedding and a comfortable resting area
- reviewing hoof balance and foot care regularly.
Older or significantly stiff horses may also benefit from management changes that make everyday activities easier, such as conveniently positioned feed and water and safe access to turnout.
Bodyweight is particularly important
Excess bodyweight increases the mechanical load placed upon joints.
Keeping an arthritic horse at an appropriate body condition can therefore be one of the most useful things an owner can do.
Weight management should not mean simply restricting nutrition without considering the horse's overall dietary requirements. The aim is to provide a balanced diet while controlling excess calorie intake.
For overweight horses, gradual and appropriate weight reduction may significantly reduce the load being carried by already compromised joints.
Nutrition and joint support
No feed supplement can rebuild a severely damaged joint or replace appropriate veterinary treatment.
Nutrition can, however, form part of a broader joint-management programme.
A suitable diet should first provide the horse with balanced nutrition, including adequate quality protein, vitamins and minerals, while maintaining an appropriate bodyweight.
Joint supplements may then be used to provide nutritional ingredients intended to support normal joint tissues, mobility and comfort.
Freestep joint support
Freestep joint-support products can be used as part of the nutritional management of horses where maintaining joint mobility and comfort is a priority.
They should be considered alongside — rather than instead of — appropriate veterinary investigation, weight management, hoof care and an exercise programme suited to the individual horse.

The importance of hoof balance
The way a horse's feet are trimmed or shod affects how forces travel through the limbs.
Regular, appropriate hoof care is therefore an important part of managing many horses with joint disease.
Where arthritis is causing lameness, the veterinary surgeon and hoof-care professional may sometimes work together to modify trimming or shoeing with the aim of improving comfort and reducing undesirable loading.
There is no single trimming or shoeing solution suitable for every arthritic horse.
Older horses
Osteoarthritis becomes increasingly common as horses age, but reduced mobility should not automatically be dismissed as an inevitable consequence of getting older.
An older horse that becomes progressively stiffer, struggles to rise, stops rolling, becomes reluctant to have its feet lifted or changes the way it moves may be experiencing discomfort that could potentially be managed.
Good management can make a substantial difference to the quality of life of an older horse with osteoarthritis.
When should I call my vet?
Seek veterinary advice if your horse develops:
- new or unexplained lameness
- persistent or worsening stiffness
- a hot, painful or swollen joint
- a sudden deterioration in movement
- reluctance to bear weight on a limb
- a significant reduction in performance
- difficulty getting up or lying down
- signs of persistent pain.
Sudden severe lameness should not simply be assumed to be arthritis. Other potentially serious causes need to be considered.
The outlook
Osteoarthritis is usually a lifelong condition, but diagnosis does not necessarily mean the end of a horse's ridden or active life.
Some horses with relatively advanced joint changes remain comfortable and useful with appropriate management, while others require a reduction or change in workload.
Regular reassessment is important because the horse's requirements may change over time.
The aim is not simply to treat an X-ray. It is to keep the individual horse as comfortable, mobile and capable as possible while protecting its long-term welfare.
Key points
- Osteoarthritis is the most common form of arthritis in horses.
- It can affect horses of any age, although it becomes increasingly common with age.
- OA involves the whole joint and is not simply "wear and tear".
- Signs can be subtle and may initially appear as stiffness or reduced performance.
- Veterinary diagnosis is important because many other conditions can cause similar signs.
- Appropriate regular movement is often valuable, although exercise must suit the individual horse.
- Maintaining an appropriate bodyweight reduces unnecessary loading of affected joints.
- Hoof balance, exercise, veterinary treatment and nutrition can all form part of long-term management.
- Joint supplements are supportive management tools rather than treatments that reverse established joint damage.
- Many horses with osteoarthritis can remain comfortable and active for considerable periods with appropriate management.
