Joint Injection

A joint injection is a procedure in which medicines are injected directly into the affected joint of the dog to treat pain and inflammation.

This treatment bypasses the bloodstream, so the medicine acts immediately where it is needed. Particularly in cases of arthritis or after injuries, it can help dogs regain more freedom of movement.

Which medicines are injected into the joint?

Corticosteroids have a strong anti-inflammatory effect but are not the first choice for joints: intra-articular corticosteroids are considered damaging to cartilage in dogs and are only used as a last resort when other treatments have been exhausted.

Hyaluronic acid is supposed to act as an artificial joint lubricant. Its benefit for arthritis is considered questionable according to the MSD Veterinary Manual; there are no reliable data on onset of action and duration of effect.

PRP (Platelet Rich Plasma) is obtained from the dog’s own blood. This treatment usually costs between 300 and 600 euros because it is more involved. Success rates are inconsistent; it often works better in younger dogs with fresh injuries than in severe arthritis.

Stem cell injections are considered experimental and often cost over 1000 euros. Long-term studies on this are scarce; here, observation of your own dog counts more than promises.

When is a joint injection appropriate?

The classic candidate: an older dog that gets up stiff in the morning and runs fluidly again after the first few metres. When painkillers alone are no longer sufficient or cause side effects.

Vets often use them preventatively after operations to curb inflammatory reactions. In acute injuries such as cruciate ligament tears, they can bridge the time until surgery.

A borderline case is very young dogs. Here, there is a greater risk that repeated injections will impair the still-growing joint.

What does the treatment really achieve?

Reliable data on how quickly and how long a joint injection works are not provided by veterinary medical literature.

The main advantage lies in the local effect. While a tablet burdens the whole body, the injected medicine reaches high concentrations directly at the problem site. This often means fewer side effects with better efficacy.

Realistic expectation: The injection does not turn a lame dog into a puppy. However, it can make the difference between “still able to go for walks” and “just lying around”.

What risks exist?

Infections are rare but serious. The joint is normally sterile; introduced bacteria can cause severe damage. Reputable vets work under surgical conditions.

Temporary worsening is more common. Some dogs limp more heavily for a day after the injection than before. This is usually due to mechanical irritation by the needle.

With repeated cortisone injections, the cartilage can suffer. Hence the rule of three per year, which reputable vets adhere to.

How does the treatment proceed?

Most dogs do not need general anaesthesia; light sedation is sufficient. The procedure itself takes minutes, while preparation takes longer.

After the injection, your dog should be kept quiet for 24 to 48 hours. Short walks on a lead are okay, but no running around or climbing stairs.

The first few days after treatment can be misleading. Sometimes the effect is delayed, or the initial improvement levels off again before the actual effect kicks in.

How much does a joint injection cost?

Simple cortisone injections start at around 80 to 150 euros. Hyaluronic acid usually costs between 150 and 300 euros, while PRP treatments can reach 500 euros.

These prices apply to a single treatment. For larger dogs or multiple affected joints, the costs rise accordingly.

When should you become sceptical?

Be wary of vets who want to sell you a whole series of injections straight away. A credible approach is: one injection first, then see how it works.

Healing promises for severe arthritis are unrealistic. The injection can restore quality of life, but it cannot create new joints.
