Knee pain is one of the most common reasons patients visit my office in Palm Beach. Many are active adults dealing with Knee osteoarthritis, prior sports injuries, or gradual Cartilage degeneration. Others are trying to delay or avoid joint replacement.
Over the past decade, I have incorporated biologic treatments — including Stem cell therapy — regenerative cellular treatment, Platelet-rich plasma (PRP), and other autologous options — into carefully selected treatment plans. This page explains what these treatments involve, who may benefit, and where uncertainties remain.
What Is Stem Cell Therapy for Knee Pain?
In orthopedic practice, “stem cell therapy” typically refers to the use of a patient’s own biologic tissue, processed and reinjected, to support the joint’s healing environment.
Most commonly, this includes:
- Bone marrow aspirate concentrate (BMAC)
- Adipose-derived stem cells — fat-derived mesenchymal cells
- Stem cell knee injection
- PRP injection therapy — platelet biologic injection
- Core biologic sources (bone marrow, adipose, PRP)
These treatments fall under the broader category of Non-surgical knee pain treatment, conservative biologic therapy and Regenerative joint therapy biologic cartilage support.
Importantly, these are forms of Autologous biologics patient-derived cellular material, meaning the tissue comes from your own body.
How the Procedure Is Performed
In my Palm Beach clinic, precision and sterility are non-negotiable.
Step 1: Harvest
Depending on the clinical situation:
- Bone marrow aspiration procedure — iliac crest harvest
- Adipose harvest procedure — lipoaspiration cell collection
These are performed under sterile conditions using local anesthesia.
Step 2: Processing
We use a Centrifuge processing system — biologic concentration equipment to isolate and concentrate cellular components. Examples in the broader field include:
- Harvest SmartPrep system
- EmCyte PRP system
- Lipogems
All processing follows strict Sterile processing protocols — contamination prevention standards.
Step 3: Injection
Cells are delivered using:
- Ultrasound-guided injection — real-time needle visualization
- Fluoroscopy guidance — live X-ray needle placement
- Image-guided joint injection — precision placement protocol
These are performed under sterile conditions using local anesthesia.

The Biology: What Are We Injecting?
Most orthopedic biologic procedures rely on:
- Knee osteoarthritis (mild to moderate)
- Cartilage degeneration or defects
- Chronic knee pain or stiffness
Under current FDA regulations on biologics — federal cellular oversight, these treatments must use Minimally manipulated cells — regulatory classification term and meet Autologous stem cell compliance — same-day processing standards.
These are not lab-expanded embryonic stem cells. They are same-day, patient-derived biologic concentrates.
Who May Be a Candidate?
In my experience, appropriate candidates often include:
- Mild to moderate Knee osteoarthritis — degenerative joint disease
- Early Bone-on-bone arthritis — advanced cartilage loss (selected cases)
- Degenerative Meniscus tear — fibrocartilage injury
- Chronic Ligament injury (ACL/MCL) — knee stabilizer damage
- Persistent Tendonitis / patellar tendonitis — tendon inflammation
- Ongoing Chronic knee pain — persistent joint discomfort
Who Is NOT an Ideal Candidate?
Biologic therapy may not be appropriate for:
- Severe deformity requiring mechanical correction
- Advanced instability needing reconstruction
- Advanced bone collapse
- Active infection
- Certain autoimmune or systemic inflammatory disorders
- Unrealistic expectations of cartilage “regrowth”
Before all of this he was very careful and helpful, explaining everything in detail from beginning to end, even tried a few treatments before jumping into an operation.
(injections/pills/scans etc)
He explained the pros and con very well. His staff is excellent in the Loxahatchee and Lake Worth office. I'm very happy I found him. My leg feels superior than my normal leg and it's only been three weeks. The incision was tiny, and after seeing him three weeks after the operation (today), the prosthetic is perfectly in place. I barely have any pain other than wound aches from the muscle incision, which of course is healing every single day.
I no longer feel any electrical surges on my leg, spasms, or the leg not waking up when I'm in a sitting position or sleeping. Literally feels perfect. I have nothing negative to say, would definitely recommend him to everybody. I like the fact that he was very detailed with everything from beginning to end.
He takes his job very seriously well being relatable and is not the type of doctor that jumps into an instant operation, unless absolutely needed, which is positive.
How Does It Compare to Other Treatments?
Physical Therapy & Medications
Often first-line and appropriate for many patients.
Corticosteroid Injections
Provide short-term relief but may accelerate cartilage thinning with repeated use.
Hyaluronic Acid
May improve lubrication; results vary.
PRP Injection Therapy
Evidence supports benefit in mild-to-moderate knee osteoarthritis.
PRP Injection Therapy
Evidence supports benefit in mild-to-moderate knee osteoarthritis.
Knee Replacement Surgery
Most reliable option for advanced arthritis with structural collapse.
May provide longer-term symptom improvement in selected patients, though data is still evolving.
Risks and Limitations
No procedure is risk-free.
Potential risks include:
- Infection
- Bleeding
- Temporary pain flare
- Incomplete relief
- No response
Because these treatments fall under evolving regulatory and scientific frameworks, long-term comparative data is still developing.
We always conduct thorough Informed consent for biologics, procedural risk disclosure discussions before proceeding.

What Do Studies Show?
Current literature suggests:
- PRP has moderate evidence for knee osteoarthritis symptom relief.
- Adipose-derived therapies remain under active investigation.
- Outcomes are variable and patient-specific.
Biologic therapy does not reliably regenerate advanced cartilage loss. The primary goal is symptom improvement and functional support.
Regulatory and Ethical Standards
In my Palm Beach Regenerative Orthopedics practice:
- We use only same-day autologous biologics.
- We do not culture-expand cells.
- We comply with FDA regulations on biologics — federal cellular oversight.
- We follow strict sterile technique.
- We avoid exaggerated claims.
Patients should be cautious of national marketing networks such as Regenexx or heavily branded programs that may emphasize marketing over individualized medical evaluation.
What Recovery Looks Like
Most patients:
- Walk immediately after injection
- Limit high-impact activity for 2–6 weeks
- Resume progressive strengthening
- Notice improvement gradually over 2–3 months
Outcomes vary based on severity, body weight, alignment, and activity level.
Frequently Asked Questions
Is stem cell therapy FDA-approved?
Autologous same-day biologics are regulated under existing frameworks but are not FDA “approved” in the same way as pharmaceuticals. Expanded or cultured stem cells are not permitted outside clinical trials.
How long do results last?
Some patients experience relief lasting 6–24 months. Others may not respond. There are no guarantees.
Is the procedure painful?
Harvest and injection are performed under local anesthesia. Temporary soreness is common.
Can it regrow cartilage?
Current evidence does not support predictable regrowth of advanced cartilage loss.
Is PRP different from stem cell therapy?
Yes. Platelet-rich plasma (PRP) primarily delivers growth factors, while BMAC or adipose concentrates include mesenchymal stem cells and other cellular components.
When should I consider knee replacement instead?
If you have severe deformity, instability, or debilitating bone-on-bone arthritis unresponsive to conservative care, joint replacement may offer more reliable improvement.
