Knee Osteoarthritis Treatment – Platelet Rich Plasma Therapy


Platelet-rich plasma or PRP therapy is an injection therapy that uses your own blood platelets to promote healing of musculoskeletal conditions. For many patients it can provide a long lasting healing.

PRP is derived from your own blood that consists of a combination of growth factors and platelets.Platelets and growth factors are components of the body’s natural system. When the body suffers a soft-tissue injury, its natural response is to deliver platelet cells to the area. Platelets and other cells initiate repair and attract the critical assistance of native stem cells (rebuilding cells). PRP therapy’s natural healing process intensifies the body’s efforts by delivering a higher concentration of platelets directly into an area of injury.

To create platelet-rich plasma therapy, a small sample of your blood is drawn, similar to a lab-test sample. The blood is placed in a centrifuge which separates the platelets from the other components. The concentrated platelet-rich plasma is then injected into and around the point of injury, jump-starting and significantly strengthening the body’s natural healing signal. Because the patient’s own blood is used, there is no risk of a transmissible infection and a very low risk of allergic reaction.

Researchers suggest that Platelet Rich Plasma Injections (PRP) are an effective treatment for patients with knee osteoarthritis. The treatments are considered safe, economical and more importantly provide good and long-lasting symptomatic relief to patients with knee pain.

Much of the research surrounding Platelet Rich Plasma Therapy treatments for knee osteoarthritis is considered preliminary or sometimes “controversial,” because the treatment itself is considered somewhat controversial. Surgeons and practitioners know how difficult it can be to choose a treatment for cartilage injuries such as osteochondral fractures, avascular necrosis, osteochondritis and degenerative processes like osteoarthritis and rheumatisms.

“The results showed considerable improvement”

An August 2019 study (1) examined the outcomes of patients receiving PRP in “the treatment of knee joint cartilage injuries and degenerative meniscus lesions as well as pain relief.”

The researchers looked at 126 patients, 56 men, 70 women, who had 3 doses of PRP for 7 days as well as 3 and 6 months after the application of PRP. The results showed considerable improvement 3 months after the PRP application, and 6 months after the application the results remained approximately identical.

The researchers concluded: “The application of PRP in the field of medicine is widely applied, and it will continue to be because the understanding of PRP therapy is increasingly refined. This therapy represents a potential and latest method in short-term pain reduction, but additional studies are needed to prove its long-term effectiveness.”

A September 2019 study (2) investigated “the effects of intra-articular platelet-rich plasma (injections) on the femoral cartilage thickness, pain, functional status, and quality of life of patients with knee osteoarthritis.”

Here a total of 71 patients (109 knees – 38 of the patients had both knees treated) with knee osteoarthritis who were administered PRP injections twice with two-week intervals. Using various standard scoring systems, the patient’s response was measures for pain response, activity level, and quality of life scores were recorded at the baseline and 1-month, 3-month, and 6-month follow ups. The femoral cartilage thickness was measured via ultrasonography before treatment, and at 3-month and 6-month follow ups.

  • The resting and activity pain scores were significantly improved at 1-month, 3-month and 6-month follow ups when compared to the pre-injection values.
  • Significant reductions were found in the pain, stiffness, and function scores at 1, 3, and 6 months
  • Significant improvements were determined in the physical functioning, physical role, pain, general health, and emotional role sub-scores during the 6-month period.

CONCLUSIONS: “The results of (this) study indicated that the (PRP) injections improved the pain, stiffness, physical functioning, and quality of life of knee osteoarthritis patients; however, they did not seem to affect the cartilage thickness during the 6-month follow up period.

The importance of an experienced PRP physician

The results of PRP injections can vary greatly. A key component of this is in the variability of how the treatment is offered and the experience of the doctor offering th treatment.

The importance of an experienced PRP physician, one with extensive clinical experience in treating patients with injection therapies, can make the difference between PRP treatments working or not working. Some believe PRP is a one time injection. This is not always the case.

At the Magaziner Center for Wellness We take a holistic view of the body, even from an orthopaedic standpoint. We believe it is crucial to obtain recovery from an injury or to cure chronic pain; PRP cannot be given just into that injured joint. We need to look at joints above and below the injury, and make sure they are stable. If these areas are left unstable, and not treated with PRP, then the original injury has a greater chance to recur.

We believe that PRP must correct both the injury and the mechanics of the body. For example, if you are suffering from knee pain, and only treat the knee, but fail to realize that the foot and ankle are unstable, then eventually the knee will become re-injured!

PRP treatment showed positive effects in patients with knee osteoarthritis in multi-studies

Here is a recent study (3) where the patients received two injections of PRP as the “complete treatment.” Even in this limited treatment positive results were recorded.

Researchers in Italy looked at active lifestyle patients with cartilage lesions and evaluated the effectiveness of PRP injections.

Of the 50 patients studied, 25 had a previous surgery for cartilage repair. The other 25 had no surgical history.

Conclusions: “The PRP treatment showed positive effects in patients with knee osteoarthritis. Operated and nonoperated patients showed significant improvement by means of diminishing pain and improved symptoms and quality of life.

Clinical Relevance: There are only a few studies of PRP treatment for cartilage on osteoarthritic knees. Different PRP products might be more or less appropriate to treat different types of tissues and pathologies. The clinical efficacy of PRP remains under debate, and a standardized protocol has not yet been established.”

What all this research shows is that for the best chance for PRP to work for your knee pain, you need a doctor experienced in offering the treatment. PRP injection is not cortisone, it is a growth and repair mechanism and as such requires observation after treatment, adjustments after treatment, supportive treatments to treat the whole. A single injection of PRP will offer lead to non-conclusive results – people in pain need a “conclusion.”

At the Magaziner Center for Wellness we use protocols established based on empirical observation and science combined with clinical experience with our patients.

How long does PRP take to work?

Initial improvement may be seen within a few weeks, depending on the injury or condition, gradually increasing as the healing progresses. Research studies and use in clinical practice have shown PRP therapy to be very effective at relieving pain and quickly returning patients to their normal routine. Both ultrasound and MRI images have shown definitive tissue repair after PRP therapy, confirming the healing process. The need for surgery can also be greatly reduced by treating injured tissues before the damage progresses and the condition becomes irreversible. The procedure takes approximately one hour, including preparation and recovery time. PRP therapy relieves pain without the risks involved with surgery, general anesthesia, or hospital stays, and does not require a prolonged recovery. In fact, most people return to their jobs or usual activities immediately afterwards.
