Knee Osteoarthritis Treatment: Effective Options for Osteoarthritis of the Knee Joint
Knee osteoarthritis is a pain that makes your world smaller.
First, you think twice about taking the stairs. Then longer walks become less appealing. Eventually, you may find yourself checking whether a restaurant has close parking or wondering how much walking a family outing will involve.
That is when people begin to take a serious look at knee osteoarthritis treatment.
The good thing is that the treatment does not only involve painkillers at one extreme and knee replacement at the other. It involves a number of steps in between, and the right method is based on the level of development of arthritis, the extent to which it is impacting your life, and what you have already tried.
Why Does an Arthritic Knee Hurt So Much?
Osteoarthritis is often described as “wear and tear,” but that description is a little too simple.
The cartilage that cushions the bones in the knee gradually deteriorates. Meanwhile, changes may take place within the joint, such as inflammation, bone alterations and irritation of tissues around it.
You may notice:
- Pain during or after activity
- Stiffness after sitting or waking up
- Swelling around the knee
- Difficulty bending or straightening the leg
- Grinding or crackling sensations
- Trouble climbing stairs or walking longer distances
Visible arthritis on an X-ray may not directly correlate with the amount of pain a person experiences. This is one of the reasons why treatment must be based on the individual, not merely the scan.
Start With the Basics, Because They Actually Matter
A good osteoarthritis knee treatment plan often starts conservatively.
One of the most effective tools is exercise. Building the muscles surrounding the knee may help to support the joint, and low-impact exercises, including cycling, swimming and walking, can be used to keep the joint moving.
Physical therapy can also be used to enhance strength, flexibility and movement patterns.
A gradual decrease in weight in the case of overweight patients may reduce the pressure on the knee. Even everyday adjustments, such as changing activities or using a brace or walking aid when appropriate, may make movement easier.
What About Medication and Knee Injections?
Medication may be used to control symptoms, especially when the flare-ups are painful.
Based on your health history, a doctor can prescribe topical or oral anti-inflammatory medication. Some patients may also be suitable to take acetaminophen.
Some individuals may be relieved by corticosteroid injections into the knee, albeit temporarily. There are other types of injections as well, but their effectiveness differs, and not all types are regularly recommended for knee osteoarthritis.
The important question is not simply, “What can stop the pain today?” It is also, “What makes sense if the pain keeps coming back?”
When Conservative Treatment Is No Longer Enough
This is where the conversation becomes more interesting.
Some people reach an awkward middle ground: exercise, medication and injections are no longer providing enough relief, but they are not ready for, or may not be a good candidate for, knee replacement.
One emerging option for selected patients is Genicular Artery Embolization (GAE).
GAE takes a completely different approach to knee pain.
Chronic osteoarthritis can be associated with inflammation and the development of abnormal small blood vessels around the inflamed lining of the knee. During GAE, an interventional radiologist guides a tiny catheter toward specific genicular arteries supplying these areas and introduces microscopic particles to reduce abnormal blood flow.
The goal is to reduce inflammation-related pain while leaving the knee joint itself intact.
GAE is an image-guided, outpatient, minimally invasive procedure performed. There are no large surgical cuts, and patients usually go home after surgery.
Not all arthritic knees respond well to GAE, and studies are ongoing to establish the most beneficial patients. A specialist evaluation is essential.
And When Is Knee Replacement Considered?
Partial or total knee replacement can ultimately be suggested in severe arthritis that significantly impacts the quality of life and has failed to respond to other therapy.
Joint replacement can be very effective in the right patient; it is a difficult surgery and necessitates rehabilitation.
This is why knee joint treatment should not be viewed as a choice between “doing nothing” and surgery. There is a spectrum of care in between.
Frequently Asked Questions
- Is it possible to cure knee osteoarthritis?
No treatment can completely rehabilitate an osteoarthritic knee to its former status. Therapy aims at pain management, mobility, better functioning and delaying the effect of the condition on daily life.
- Is walking good for knee osteoarthritis?
Usually, yes. Appropriate exercise is an important part of osteoarthritis management. The type and intensity should be adjusted to your symptoms and physical abilities.
- When should I consider GAE?
GAE can be recommended to patients with chronic knee pain due to osteoarthritis who have not achieved sufficient pain relief with conservative care and are interested in a minimally invasive procedure.
- Does GAE replace knee replacement?
No. They are different treatments for different circumstances. GAE may help certain patients manage pain or potentially delay surgery, while advanced joint damage may ultimately require knee replacement.
- How long does GAE take?
South Florida Vascular Associates generally performs the outpatient procedure in approximately 60 to 90 minutes. Individual treatment and recovery experiences vary.
Your Next Step Does Not Have to Be Knee Surgery
Being a patient with knee arthritis can gradually alter what you do and what you stop doing.
When medication, injections and conservative care are not giving you the relief you need, it might be worth considering what other options are available.
South Florida Vascular Associates provides Genicular Artery Embolization to properly chosen patients who require a minimally invasive solution to knee pain caused by osteoarthritis.
