What’s Inside a PRP Injection? A Look at What Heals Your Knee From Within

If you’ve ever winced while standing up, felt a sharp sting walking down stairs, or found your favorite hobby suddenly on hold because of knee pain—welcome to the club. You’re not alone, especially in active communities like The Villages, where staying mobile and independent is a big part of life. And if you've been exploring alternatives to surgery or long-term medication, you might’ve stumbled across something called PRP treatment for knee pain.

But what exactly is PRP? More importantly, what’s inside that tiny injection that promises to heal your knee from the inside out? Let’s take a deep dive—because this isn’t just about buzzwords or trendy treatments. This is about your body healing itself with a little help from science.

The Buzz About PRP Therapy

PRP stands for Platelet-Rich Plasma, a treatment that’s gained massive attention in both sports medicine and regenerative therapy. From pro athletes to everyday folks walking the golf course or dancing at town square events in The Villages, people are turning to PRP therapy for knees as a non-invasive way to reduce pain and support healing.

So, why all the hype? Because PRP taps into your body’s own healing power. No foreign chemicals. No risky surgeries. Just your blood—spun, concentrated, and injected back where it’s needed most.

What’s Inside a PRP Injection?

To understand PRP, you have to know what’s in your blood. Your blood is made up of four main components:

• Red blood cells (RBCs) – They carry oxygen.

• White blood cells (WBCs) – They fight infection.

• Platelets – They help with clotting and healing.

• Plasma – The fluid that carries all of the above.

In a PRP treatment, the magic ingredient is platelets, but not just any amount. The goal is to isolate and concentrate just the right amount of platelets, mix them with your own plasma, and inject that healing cocktail back into your injured area—in this case, your knee.

Step-by-Step: How PRP is Made

1. Blood Draw: First, your provider takes a small amount of your blood—usually about 10–30 milliliters (just a few teaspoons).

2. Centrifuge Magic: That blood goes into a centrifuge, a high-speed spinning machine that separates the components based on density.

3. Concentration: The red and white blood cells are filtered out, leaving behind a golden fluid rich in platelets—your PRP.

4. Injection: That concentrated PRP is then injected directly into your knee joint, precisely where healing is needed.

   
   

What’s So Special About Platelets?

We all know platelets help clot your blood when you get a cut. But they do much more. Platelets are packed with growth factors, which are proteins that signal your body to repair damaged tissues. Think of growth factors like construction foremen—directing your body’s repair team to rebuild cartilage, reduce inflammation, and regenerate tissue.

Some of the key growth factors include:

• PDGF (Platelet-Derived Growth Factor) – Stimulates new blood vessels and repairs connective tissue.

• TGF-β (Transforming Growth Factor Beta) – Regulates cell growth and reduces inflammation.

• VEGF (Vascular Endothelial Growth Factor) – Promotes blood flow to support tissue recovery.

These factors are crucial for joint healing, especially when it comes to wear-and-tear damage like arthritis or overuse injuries.

PRP Treatment for Knee: Who Can Benefit?

PRP therapy is increasingly popular for treating knee osteoarthritis, ligament injuries, meniscus tears, and tendon inflammation. If you’ve been living with chronic pain, stiffness, swelling, or even that annoying cracking or popping sound in your knee, PRP could be worth considering.

You may be a good candidate for PRP treatment for knee if:

• You want to avoid or delay surgery.

• You’ve tried physical therapy or medications with little relief.

• You’re active and want to stay that way.

• You prefer a more natural, regenerative approach to healing.

PRP vs. Traditional Treatments

Let’s compare PRP to the typical options:

Treatment	What It Does	Pros	Cons
Cortisone Shots	Reduces inflammation	Fast relief	Can weaken cartilage over time
Pain Medications	Masks pain	Easy to use	Doesn’t treat the cause
Knee Surgery	Replaces joint/damaged tissue	Long-term solution	Risky, expensive, long recovery
PRP Therapy	Regenerates tissue	Natural, outpatient, low-risk	Takes time for results

PRP doesn’t work overnight, but it addresses the root cause by helping the body heal damaged tissue from the inside out.

What’s It Like to Get a PRP Injection?

At Legacy Clinic of Chiropractic in The Villages, PRP therapy is a quick, in-office procedure. Here’s what to expect:

1. Consultation – Your provider evaluates your condition, often using imaging like ultrasound.

2. Draw + Process – Your blood is drawn and spun, usually within 15 minutes.

3. Injection – The PRP is injected into the affected knee using a fine needle—guided by imaging for pinpoint accuracy.

4. Post-Treatment Plan – You’ll be advised to rest the knee, avoid NSAIDs (like ibuprofen), and gradually resume activity.

   
   

Most people report mild soreness post-injection, which is a normal sign that the healing process has begun.

Real Stories, Real Healing

Let’s bring it to life. Take Donna, a 67-year-old avid pickleball player from The Villages. After struggling with knee pain for over a year and missing her favorite tournaments, she tried PRP therapy for knees at Legacy Clinic of Chiropractic. Within three months of her PRP series, her pain dramatically decreased—and she was back on the court, playing stronger than ever.

Or John, a former marathon runner who couldn’t walk a mile without knee swelling. After PRP treatment, combined with physical therapy and stretching, he’s now back to hiking with his grandkids. Stories like these are becoming more common—and that’s no coincidence.

How Long Does It Take to Work?

Patience is key. Unlike cortisone shots that kick in fast and fade just as quickly, PRP therapy is a slow-build. You may start noticing improvements in pain and mobility within 2 to 6 weeks, with continued healing for up to 6 months after injection.

Some patients may need multiple sessions depending on severity, but many experience long-lasting relief from just one or two treatments.

Is PRP Safe?

Since PRP uses your own blood, there’s virtually no risk of allergic reactions or rejection. Complications are rare and usually limited to temporary swelling, soreness, or bruising at the injection site.

Plus, when performed by an experienced provider—like those at Legacy Clinic of Chiropractic—it’s a safe, scientifically-backed method with a growing body of positive research supporting its effectiveness.

The Science Speaks: PRP Is More Than Hype

Here’s the thing—this isn’t just a wellness trend. Medical journals now recognize PRP as a promising option for orthopedic conditions. Several studies show:

• Improved knee function and pain relief in patients with early-stage osteoarthritis.

• Reduced need for surgery or ongoing medications.

• Long-term improvement in joint mobility and cartilage preservation.

And for active adults in The Villages, staying mobile without surgery is a huge win.
