What Is nStride (APS Therapy)?

nStride (Autologous Protein Solution) is a regenerative injection treatment designed specifically for knee osteoarthritis.

It is created from your own blood and contains:

• Anti-inflammatory proteins
• Growth factors that support joint health
• Biological mediators that help rebalance inflammation within the joint

Unlike standard injections, nStride is designed to target the underlying inflammatory processes driving osteoarthritis symptoms.

How Does nStride Work?

The procedure is completed in clinic:

1. A blood sample is taken
2. It is processed to create a concentrated protein solution
3. The APS is injected into the knee joint

At Pro Sports Medicine, injections are performed using ultrasound guidance to ensure precise placement and optimal results. The entire procedure typically takes under one hour.

What Can nStride Treat?

nStride is specifically used for Knee Osteoarthritis

• Early to moderate arthritis
• Persistent knee pain
• Joint stiffness and swelling
• Reduced function or activity limitation

It is particularly beneficial for patients who:

• Have not improved with physiotherapy
• Want to avoid or delay knee surgery
• Are not yet ready for joint replacement

Why nStride Is Different

nStride is not simply a pain-relieving injection.

It is designed to:

• Reduce inflammation within the joint
• Improve joint environment
• Support longer-term symptom improvement
