Knee osteoarthritis (OA) is one of the most common causes of joint pain and mobility limitation, especially as we age. While it can’t be reversed entirely, there are effective treatments that may reduce discomfort, improve function, and help you stay active longer, often without surgery.
This guide explains what knee osteoarthritis is, how it develops, and how treatments like hyaluronic acid injections and PRP (platelet-rich plasma) may support joint health.
How Do I Know If I Might Have Knee Osteoarthritis?
Common signs include:
- Knee soreness after activity or prolonged rest
- Morning stiffness or stiffness after sitting
- Pain when climbing stairs or standing up from a chair
- Clicking, grinding, or catching sensations in the knee
- Reduced ability to exercise comfortably
- Worsening pain later in the day
- Muscle weakness around the knee
If you’re experiencing these symptoms, evaluation with imaging and clinical assessment can help confirm a diagnosis and guide treatment.
What Makes Osteoarthritis Different From Other Types of Arthritis?
Osteoarthritis is primarily a degenerative joint condition. It develops when the protective cartilage that cushions your bones gradually breaks down. This differs from inflammatory types of arthritis (like rheumatoid arthritis), which involve immune system activity.
Knee OA is extremely common and affects millions of Americans, often impacting daily activities and quality of life.
Why Osteoarthritis Causes Knee Pain
Several changes occur inside the joint:
Loss of Hyaluronic Acid
Healthy joints contain synovial fluid rich in hyaluronic acid, which:
- Lubricates joint movement
- Absorbs shock
- Protects cartilage surfaces
With osteoarthritis, this fluid becomes thinner and less effective.
Cartilage Breakdown
Cartilage acts as a cushion between bones. As it wears down:
- Bones may rub together
- Pain and inflammation increase
- Mobility becomes more limited
Bone and Soft Tissue Changes
You may also see:
- Bone spurs (osteophytes)
- Thickened joint capsule
- Inflammation inside the joint
These changes create a cycle of pain and reduced movement.
Are All Knee Injections the Same?
No. Different injections target different aspects of osteoarthritis.
Steroid (Cortisone) Injections
- Reduce inflammation quickly
- Often provide short-term relief
- Not typically a long-term solution
Hyaluronic Acid Injections (Durolane®, Supartz®, etc.)
These injections aim to restore lubrication in the joint by supplementing hyaluronic acid.
Potential benefits include:
- Improved joint cushioning
- Reduced pain and stiffness
- Enhanced mobility
- Effects that may last several months
PRP (Platelet-Rich Plasma)
PRP uses your own blood-derived growth factors to support:
- Tissue repair
- Inflammation regulation
- Cartilage environment health
It is considered a regenerative therapy rather than simply a lubricant.
Combining PRP With Hyaluronic Acid: Why Some Patients Choose Both
Many patients benefit from a combined approach.
Hyaluronic acid helps mechanically:
- Improves joint lubrication
- Enhances shock absorption
PRP works biologically:
- Provides growth factors
- Supports tissue healing responses
- May reduce inflammatory signaling
Together, they may:
- Improve comfort more than either treatment alone for some patients
- Support longer-lasting symptom relief
- Help maintain joint function
Research is still evolving, but combination therapy is increasingly used in regenerative orthopedics.
Can These Treatments Delay Knee Replacement?
While not guaranteed, some studies suggest hyaluronic acid injections and PRP , especially repeated courses, may delay the need for knee replacement surgery in certain patients.
This depends on:
- Severity of arthritis
- Activity level
- Weight management
- Overall joint health
Early treatment often provides better outcomes.
Lifestyle Still Matters
Injection therapies work best alongside:
- Strengthening the muscles around the knee
- Weight management
- Low-impact exercise (cycling, swimming, walking)
- Anti-inflammatory nutrition and wellness support
Joint health is always multifactorial.
The Nervana Medical Approach to Knee Osteoarthritis
At Nervana Medical, we take a personalized, integrative approach that may include:
- Hyaluronic acid injections (Durolane®, Supartz®, etc.)
- PRP regenerative therapy
- Combination protocols when appropriate
- Functional medicine and wellness optimization
- Non-surgical joint preservation strategies
Our goal is to help you stay active, mobile, and comfortable while minimizing invasive interventions whenever possible.
Final Thoughts
Knee osteoarthritis doesn’t mean you have to stop doing what you love. Modern treatments, especially regenerative options, can provide meaningful symptom relief and support long-term joint health when used appropriately.
If knee pain is limiting your quality of life, a consultation can help determine the best options for you.

Knee Osteoarthritis FAQ
Nervana Medical | Joint Health & Regenerative Medicine
How do I know if I might have knee osteoarthritis?
Common symptoms include:
- Knee pain after activity or prolonged sitting
- Morning stiffness or stiffness after rest
- Pain climbing stairs or standing up
- Clicking, grinding, or catching sensations
- Reduced ability to exercise comfortably
- Weakness around the knee joint
- Pain that worsens later in the day
If you notice these symptoms, an evaluation with imaging and clinical assessment can help confirm whether osteoarthritis is present.
What exactly is knee osteoarthritis?
Knee osteoarthritis is a degenerative joint condition where the cartilage cushioning your knee gradually wears down. As cartilage thins, the joint becomes less protected, leading to inflammation, stiffness, and pain with movement.
Why does osteoarthritis cause knee pain?
Several factors contribute:
- Reduced joint lubrication from decreased hyaluronic acid
- Cartilage breakdown causing bone friction
- Bone spur formation
- Joint capsule inflammation or thickening
- Muscle weakness that reduces joint stability
Together, these changes create a cycle of pain and reduced mobility.
What is hyaluronic acid and why is it important?
Hyaluronic acid is a naturally occurring substance in joint fluid that helps:
- Lubricate movement
- Absorb shock
- Protect cartilage surfaces
In osteoarthritis, this fluid becomes thinner and less effective, which contributes to joint discomfort.
What are hyaluronic acid injections (Durolane®, Supartz®, etc.)?
These injections supplement the joint with hyaluronic acid to:
- Improve lubrication
- Reduce stiffness and pain
- Support joint mobility
- Provide relief that may last several months
They are often considered when conservative treatments haven’t provided enough relief.
How are steroid injections different?
Steroid (cortisone) injections:
- Reduce inflammation quickly
- Often provide short-term relief
- Typically don’t last as long as hyaluronic acid injections
Both have a role, depending on your symptoms and goals.
What is PRP therapy for knee osteoarthritis?
PRP (platelet-rich plasma) uses growth factors from your own blood to support:
- Tissue repair
- Reduced inflammation
- Joint environment health
It’s considered a regenerative therapy rather than simply a lubricant.
Can PRP and hyaluronic acid be used together?
Yes, combination therapy is increasingly common.
Hyaluronic acid provides:
- Mechanical cushioning and lubrication
PRP provides:
- Biological support for tissue healing
Together, they may help improve comfort and function for some patients. Research is ongoing, but many clinicians find the combination beneficial.
Can these injections delay knee replacement?
They may help delay surgery for some patients, particularly when:
- Osteoarthritis is mild to moderate
- Lifestyle factors are optimized
- Treatment is started earlier
However, results vary and replacement surgery may still eventually be needed.
Are these treatments safe?
Generally, yes when performed by trained providers.
Possible temporary side effects include:
- Mild swelling or soreness
- Temporary stiffness
- Injection site discomfort
A consultation ensures the treatment is appropriate for your situation.
What else helps knee osteoarthritis besides injections?
Best outcomes usually involve a combination approach:
- Strength training around the knee
- Weight management
- Low-impact exercise
- Anti-inflammatory lifestyle habits
- Physical therapy when indicated
Joint health is multifactorial.
How does Nervana Medical approach knee osteoarthritis?
Our approach focuses on preserving joint function and quality of life using:
- Hyaluronic acid injections

When should I consider treatment?
If knee pain is limiting your activity, affecting sleep, or interfering with daily life, evaluation can help determine whether regenerative or supportive therapies may help.
