PRP vs Cortisone for Knee Arthritis: Which Lasts Longer?

Posted on: July 13th, 2026 by Connor Ziegler

A Common Patient Story

A common patient we see is a 58-year-old active adult who loves hiking, playing tennis, and staying active with family.

Over the past several years, knee pain has slowly taken over.

At first, it was just stiffness after activity.
Then swelling.
Then pain going up and down stairs.

They tried:

• Physical therapy
• Anti-inflammatory medications
• Multiple cortisone injections

Each time, the pain improved… but only temporarily.

Eventually, they were told:
“You may need knee replacement surgery.”

The Question Many Patients Ask

“Is there anything that lasts longer than cortisone… and can help me avoid surgery?”

This is where understanding your options becomes critical.

Understanding Knee Arthritis

What is Knee Arthritis?

Knee arthritis occurs when the protective cartilage in the joint wears down over time, leading to:

• Pain
• Stiffness
• Swelling
• Reduced mobility

Why It Develops

Common contributing factors include:

• Age-related wear and tear
• Prior injuries (meniscus tears, ligament injuries)
• Repetitive stress from activity
• Genetics and inflammation

As cartilage breaks down, the joint becomes inflamed and less efficient, leading to the symptoms many patients experience daily.

Traditional Treatment Options

Most patients follow a predictable path:

1. Physical Therapy

Improves strength and stability—but may not address underlying joint degeneration.

2. Medications

Anti-inflammatories help manage symptoms but do not change the condition.

3. Cortisone Injections

Provide temporary relief by reducing inflammation.

Why Many Active Adults Want to Avoid Surgery

For patients in their 40s, 50s, and 60s:

• Knee replacement is a major surgery
• Recovery can take months
• Implants have a limited lifespan
• Activity levels may be restricted afterward

Many patients ask:

“Is there a way to stay active without going down the surgery path right now?”

PRP vs Cortisone: What’s the Difference?

Cortisone Injections

Cortisone is a powerful anti-inflammatory steroid.

What it does:

• Reduces inflammation quickly
• Provides short-term pain relief

What it does NOT do:

• Does not repair tissue
• Does not slow arthritis progression

How long does it last?

• Typically weeks to a few months

Platelet-Rich Plasma (PRP)

PRP is created using your own blood, concentrated to isolate healing components called platelets.

What it does:

• Reduces inflammation naturally
• Promotes tissue healing
• Supports joint environment improvement

How long does it last?

• Often 6–12 months or longer in appropriate patients

Which Lasts Longer? (Featured Snippet Answer)

PRP typically provides longer-lasting relief than cortisone for knee arthritis.

• Cortisone: short-term relief (weeks to months)
• PRP: longer-term improvement (months to a year or more)

PRP works by supporting the body’s natural healing response, while cortisone primarily suppresses inflammation temporarily.

Introducing Advanced Regenerative Options

Bone Marrow Aspirate (BMA)

BMA is another regenerative treatment using your body’s own healing cells derived from bone marrow.

What it does:

• Contains stem cells and growth factors
• Supports tissue repair and regeneration
• May be used for more advanced cases

What Does the Research Suggest? (Patient-Focused)

PRP Research

• Studies suggest PRP can provide longer-lasting pain relief than cortisone
• Many patients report improved function and activity levels
• Benefits may continue to improve over several months

BMA Research

• Emerging evidence suggests BMA may help in more advanced arthritis cases
• May support deeper healing due to higher cellular content
• Often considered when PRP alone is not sufficient

Important: Outcomes vary based on arthritis severity, activity level, and overall health.

• Have mild to moderate knee arthritis
