Platelet Rich Plasma for Knee Osteoarthritis: A Comparison with Mesenchymal Stem Cells

Platelet Rich Plasma for knee osteoarthritis is becoming an increasingly popular treatment option as osteoarthritis (OA) affects over 500 million people globally, making it one of the most common degenerative joint diseases. Standard treatments such as anti-inflammatory medications and hyaluronate injections offer temporary relief but fail to halt joint tissue degeneration. For many patients, this leads to more invasive options like arthroscopy or total joint replacement.

However, regenerative therapies like Platelet Rich Plasma (PRP) and Mesenchymal Stem Cells (MSCs) are gaining attention for their potential to not only treat symptoms but also slow the progression of OA. This article will compare these two treatments, drawing from a recent meta-analysis to highlight the effectiveness of each.

Understanding Platelet Rich Plasma for Knee Osteoarthritis

PRP comes from an autologous blood-derived concentrate, rich in growth factors, cytokines, and bioactive proteins that play an essential role in tissue repair and regeneration. Clinicians have widely adopted PRP therapy for treating osteoarthritis, recognizing its ability to boost the body’s natural healing processes.**

Mesenchymal Stem Cells: The Regenerative Powerhouse

Mesenchymal stem cells, typically sourced from adipose tissue or bone marrow, have shown promise in tissue regeneration. MSCs can differentiate into various cell types, including osteocytes and chondrocytes, making them a key player in repairing damaged joint tissues. Additionally, MSCs offer anti-inflammatory benefits by regulating cytokines that influence immune responses and autophagy processes within the joint.

Recent Study Results: PRP vs. MSC for Knee OA

A meta-analysis published in September 2024 compared PRP and MSC treatments for knee OA. Researchers analyzed data from studies conducted between 2018 and 2024, using outcome measurements such as the Knee Injury and Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and the International Knee Documentation Committee (IKDC) subjective knee form.

After analyzing the results, no significant difference was found between PRP and MSCs in terms of KOOS and WOMAC scores. However, the PRP group showed higher IKDC scores, indicating better post-treatment improvements in knee function and patient-reported symptoms.

How PRP and MSCs Work in Osteoarthritis Treatment

PRP works by delivering concentrated growth factors such as insulin-like growth factor, vascular endothelial growth factor, and transforming growth factor. These molecules enhance tissue repair and regeneration by stimulating the proliferation of cells and reducing inflammation.

On the other hand, MSCs offer a more complex mode of action. These stem cells can transform into the required cell types and modulate inflammatory responses by reducing substances like tissue necrosis factor alpha and interleukins. This helps slow the degradation of cartilage and protect chondrocytes from apoptosis.

Combining PRP and MSCs for Superior Outcomes

Interestingly, some studies suggest that combining PRP and MSCs produces superior results compared to either treatment alone. The combination of PRP’s enhanced intra-articular microenvironment and MSC’s tissue differentiation abilities leads to better pain reduction and improved knee function.

Legal and FDA Considerations

Currently, the use of MSCs derived from adipose or bone marrow tissues is restricted to FDA-approved clinical trials. The FDA classifies these stem cells as drugs, requiring strict regulations and study approvals. In contrast, PRP is FDA-permitted for use, provided no additives are introduced during the preparation process.

This makes PRP a more accessible and cost-effective option, especially since it is autologous and associated with minimal side effects. Additionally, PRP therapy is less invasive than MSC harvesting, making it an appealing choice for both practitioners and patients.

Why Juventix Regenerative Medical Is the Industry Leader

At Juventix Regenerative Medical, we offer FDA-cleared PRP kits that are meticulously designed to ensure safety, sterility, and maximum efficacy. Our PRP kits produce platelet concentrate free from red blood cells and with a minimal number of leukocytes, which are vital for successful tissue regeneration.

Our product line includes the LED Activator, which uses LED light to activate platelets and begin the regenerative process. This activation is a critical step for the release of growth factors, cytokines, and bioactive proteins from the alpha granules on platelets. This method ensures sustained growth factor release without the need for chemical additives like calcium chloride or thrombin, adhering to FDA guidelines for minimum manipulation.

In addition, Juventix offers the Bio-Incubator, a patented device that transforms PRP into Injectable Platelet Rich Fibrin (PRF). PRF is known as the “second generation of platelet products” and provides an anti-inflammatory environment, making it ideal for treating inflammatory conditions such as osteoarthritis.
