Medical Management of Arthritis
Osteoarthritis (OA) is a complex condition involving inflammation and degeneration of one or more joints. Pets with OA experience pain and inflammation in various joints that interfere with the activities of daily living.
OA is diagnosed through a combination of a thorough physical examination, a palpation, and additional diagnostics including x-rays or other imaging technology.
What causes OA?
There is no single cause of OA. Many factors influence its initiation and development including:
- Body conformation
- Body condition/weight
- Abnormal joint development
- Injury history (fracture, ligament damage, muscle injury, joint infection, damage/erosion of cartilage)
- Orthopedic surgery
- Nutritional history
In fact, most pets with OA experience a combination of these factors as their OA develops and progresses.
We now know that just “getting old” is NOT a cause of OA.
Are there other signs of OA besides difficulty jumping up into a window?
Pets can exhibit many different signs when they have OA, and they do not necessarily demonstrate all the same signs all of the time. The most common signs owners may notice include:
- Difficulty getting up and down
- Walking stiffly
- Lameness in one or more legs
- Reluctance to go up and/or down stairs
- Reluctance to jump up or down
- Stiff, swollen, or sore joints
- Reluctance to be touched on some parts of the body
- Unexpected aggression towards other animals or towards humans
The veterinarian said that my pet is overweight and prescribed new food as well as some medications and nutraceuticals. Why are there so many things for me to give my pet?
Unfortunately, there is no “magic bullet” for treating OA. In fact, once OA is in place, we are not so much treating it as managing it because OA cannot be cured.
OA is a very complex disease, so managing it is a fairly complex process because we get the best results from combining multiple modalities. Typical multimodal management of arthritis generally includes the following:
Nutrition
Normalizing body condition is critical, so your veterinarian will prescribe a specific nutritional product to accomplish this goal. There is now a nutrient profile that can support the joints while helping to normalize body weight and condition. It is important to stick strictly to the prescribed nutritional program.
Pain medications
Non-steroidal Anti-Inflammatory Drugs (NSAIDs) are generally used as the first line of defense against the pain of OA. Your veterinarian will determine if your pet is a good candidate for this class of medication.
Occasionally, a corticosteroid anti-inflammatory drug will be prescribed instead of a NSAID. The two classes of medication CANNOT be used together.
Gabapentin is a pain medication that addresses chronic pain differently from NSAIDs or corticosteroids, and complements those medications. It provides a way to address the chronic nature of OA pain, and is especially helpful when the patient is older and not able to take a NSAID.
It is important never to reach into your own medicine cabinet when your pet limps or has been diagnosed with OA.
Nutraceuticals
When a nutritional supplement has medicinal effects, it is called a “nutraceutical.” There are many of these products on the market, many labeled for use with joint disease. Be sure to ask your veterinarian about the scientific data that supports nutraceuticals that she prescribes.
Alternative and Rehabilitation
Medical acupuncture can provide excellent pain relief for many pets with OA. Likewise, other physical medicine disciplines like chiropractic and medical massage may be useful.
Finally, physical rehabilitation is a discipline that translates physical therapy techniques from human medicine for application to animal patients. These techniques include (but are not limited to) therapeutic LASER, therapeutic exercise, joint mobilization, and hydrotherapy using an underwater treadmill.
Can I do anything else to help my pet be more comfortable?
There are simple things that any pet owner can provide to a pet with OA that can help with comfort and mobility. These include:
- Soft, padded bedding
- Raised food and water dishes (elbow height)
- Non-skid floor surfaces
- A ramp or stool/step for getting onto higher surfaces
- Adhering to prescribed feeding and medication recommendations
Can OA be prevented?
Allowing a kitten or puppy to grow slowly, maintaining a lean body condition throughout growth and into adulthood, is the mostimportant way to prevent OA. Growth abnormalities and injuries cannot always be predicted, so even our best efforts may not be enough to ward off OA in an older pet. That said, with slow growth, good nutrition, optimal body condition, and regular exercise, the odds of preventing or at least delaying OA are excellent. Your veterinarian will partner with you to create the best plan for your pet.
