Autologous Protein Solution (APS)/nSTRIDE

What is Autologous Protein Solution (APS)/nSTRIDE?

Autologous Protein Solution (APS), also known as nSTRIDE APS, is an medical-grade regenerative therapy that uses the anti-inflammatory proteins, and growth factors from your own blood to treat osteoarthritis, and joint pain. This non-surgical treatment aims to reduce inflammation, protect cartilage, and improve joint function, particularly in the knee.

APS is derived from a small blood sample that is processed to concentrate the body’s own protective proteins, and cytokines. These components help counteract inflammation, and promote joint health, making APS an innovative solution for patients looking to delay or avoid surgery.

How does Autologous Protein Solution (APS)/nSTRIDE work?

APS works by addressing the root cause of joint pain in osteoarthritis caused by inflammation. Rather than masking symptoms, APS targets the inflammatory cytokines within the joint, helping to slow cartilage breakdown, and promote healing.

The process includes:

Blood collection – a small amount of blood is drawn from your arm, usually during the same clinic visit.
Protein concentration – the sample is processed in a specialised device that separates, and concentrates beneficial anti-inflammatory proteins, such as interleukin-1 receptor antagonist (IL-1Ra), and other cytokines.
Injection into the joint – the enriched solution is then injected directly into the affected joint, typically the knee, under sterile conditions, and often with image guidance.

What are the benefits of Autologous Protein Solution (APS)/nSTRIDE?

Apart from offering a unique, personalised, and non-surgical solution for patients with mild to moderate osteoarthritis, some of the key benefits include:

Cartilage protection — supports long-term joint health by reducing inflammatory damage.
Long-lasting pain relief — many patients experience relief for up to 12 months or longer after a single injection.
Minimally invasive — avoids surgery, and offers a convenient outpatient treatment with minimal downtime.
Natural and personalised — uses your own biological material, reducing the risk of adverse reactions.
Targeted inflammation control — neutralises inflammatory cytokines that contribute to cartilage degradation.

Who is a suitable candidate for the treatment?

This regenerative therapy is recommended for individuals seeking relief from chronic joint pain, especially in the knee, due to osteoarthritis. It offers a non-surgical solution for those aiming to manage their symptoms, and improve joint function without resorting to more invasive procedures.

As such, you may be a good candidate for the treatment if you:

Have been diagnosed with mild to moderate knee osteoarthritis, typically early to mid-stage.
Experience persistent knee pain, stiffness or swelling that affects daily mobility, and quality of life.
Have not responded well to conventional treatments, such as pain medications, physiotherapy or steroid injections.
Are looking for a natural, biologic approach using your own blood components, which reduces the risk of allergic reactions or immune rejection.
Prefer a minimally invasive treatment option with little downtime.
Wish to delay or avoid total knee replacement surgery.
Are still able to move your joint, and have no severe structural deformities.
Do not have active infections, severe autoimmune disorders or bleeding conditions that would contraindicate an injection-based procedure.

Are there any side effects of Autologous Protein Solution (APS)/nSTRIDE?

APS is generally considered a safe, and well-tolerated treatment, especially as it is an autologous therapy, which means it is derived from your own blood. This significantly reduces the risk of allergic reactions or immune system rejection, making it suitable for many individuals who may not respond well to synthetic or pharmaceutical-based interventions.

However, like all injection-based procedures, there is a possibility of experiencing some mild, temporary side effects, such as:

A slight increase in pain during the first 24 – 48 hours as the body begins the healing response.
Bruising or redness around the area injected.
Mild joint stiffness or a sensation of tightness.
Rare risk of infection, especially if post-injection care instructions are not followed properly.
Swelling or discomfort at the injection site.
Uncommon allergic response to any materials used during the preparation or injection (not the APS itself).

Be that as it may, these effects are usually short-lived, and resolve without intervention within a few days.

What to expect after your Autologous Protein Solution (APS)/nSTRIDE injection

Following your injection, it is common to feel mild soreness, stiffness or pressure in the treated joint for a day or two. This is a normal part of the body’s inflammatory, and healing response.

Post-procedure recommendations:

Rest the joint for 24–48 hours after the injection. During this time, it is best to avoid high-impact activities such as running or jumping.
You may apply an ice pack intermittently to ease any discomfort or swelling.
Refrain from taking anti-inflammatory medications, such as ibuprofen, for a few days, as they can interfere with the body’s natural healing process activated by the APS.
Light activities like walking or stretching can usually be resumed shortly after, based on your doctor’s advice.

Recovery and improvement timeline:

Initial improvements in pain, and joint mobility may become noticeable within 1 to 2 weeks.
Progressive improvement typically continues over the next 2 to 3 months, as the biologic proteins work to reduce inflammation, and promote joint tissue repair.
A tailored rehabilitation or physiotherapy plan may be recommended to optimise results and preserve joint function.

How long do the effects last?

The benefits of APS therapy can last anywhere from 6 months to over a year, depending on several factors including:

The severity of osteoarthritis.
The overall health, and activity level of the patient.
How well the joint responds to the therapy.

Some patients experience significant pain relief, and functional improvement after just one injection. For others, repeat treatments may be considered every 9 to 12 months as part of a longer-term joint preservation strategy.

Since APS targets the underlying inflammation associated with osteoarthritis, and promotes a more stable joint environment, many patients report sustained improvement in joint comfort, and mobility over time.

Rest assured, our team (link to about us page) will assess your outcome during follow-up reviews, and discuss whether further injections or alternative strategies are needed to maintain your joint health, and quality of life.

Summary

APS is an innovative, and minimally invasive treatment that uses your body’s own powerful anti-inflammatory proteins to reduce pain, restore mobility, and protect cartilage health. Especially effective for those with knee osteoarthritis, APS offers a non-surgical solution that may help delay or even avoid joint replacement surgery altogether.
