Advanced Injection Therapies for Knee Osteoarthritis and Joint Pain

At Pro Sports Medicine, our Regenerative Medicine Clinic provides advanced non-surgical treatments designed to help reduce pain, improve function, and keep you active for longer.

Led by clinicians experienced in elite sport and musculoskeletal medicine, we offer evidence-based regenerative injection therapies for individuals suffering from knee osteoarthritis, persistent joint pain, and early degenerative changes.

Whether you’re looking to remain active in sport, continue exercising, delay surgery, or improve your quality of life, our team can help determine the most appropriate treatment pathway for you.

What is Regenerative Medicine?

Regenerative medicine focuses on supporting the body’s natural healing processes and improving joint function through advanced biological and minimally invasive treatments.

Unlike traditional pain-relieving injections that primarily reduce inflammation, regenerative treatments aim to improve the environment within the joint, helping reduce symptoms while promoting healthier joint function.

At Pro Sports Medicine, we specialise in three of the UK’s leading regenerative injection treatments for knee osteoarthritis:

Platelet Rich Plasma (PRP)

nStride® APS

Arthrosamid®

All treatments are delivered following a comprehensive clinical assessment and diagnostic evaluation where appropriate.

Conditions We Treat

Our Regenerative Medicine Clinic commonly helps patients with:

• Knee osteoarthritis
• Degenerative joint pain
• Activity-related knee pain
• Cartilage wear and degeneration
• Patients wishing to delay knee replacement surgery
• Individuals seeking alternatives to steroid injections

Our Regenerative Medicine Treatments

Platelet Rich Plasma (PRP) Injections

PRP therapy uses a concentrated portion of your own blood containing platelets and growth factors.

After a simple blood draw, the sample is processed and injected into the affected joint under ultrasound guidance.

PRP is designed to help:

• Reduce pain
• Improve joint function
• Support the body’s natural healing response
• Enhance the biological environment within the knee

PRP is particularly popular amongst active individuals, recreational athletes, and those with mild to moderate osteoarthritis.

Benefits of PRP

• Uses your own blood
• Minimally invasive
• No surgery required
• Minimal downtime
• Growing evidence supporting use in knee osteoarthritis

nStride® APS (Autologous Protein Solution)

Pro Sports Medicine is proud to offer nStride APS, one of the most advanced biologic treatments currently available for knee osteoarthritis.

nStride uses a sample of your own blood to create a highly concentrated anti-inflammatory protein solution designed to target the inflammatory processes associated with osteoarthritis.

Research has demonstrated significant improvements in pain and function in appropriately selected patients.

nStride may be suitable for:

• Moderate knee osteoarthritis
• Active individuals wishing to avoid surgery
• Patients seeking longer-lasting symptom relief
• Those who have failed conservative treatments

Benefits of nStride APS

• Uses your body’s own natural proteins
• Single treatment procedure
• Targets inflammation associated with osteoarthritis
• Can provide long-lasting improvements in symptoms
• No hospital admission required

As the only clinic in Wales offering nStride APS, Pro Sports Medicine provides access to this innovative treatment closer to home.

Arthrosamid® Injections

Arthrosamid represents a new generation of injectable treatment for knee osteoarthritis.

Unlike PRP and nStride, Arthrosamid is a non-biodegradable hydrogel that integrates into the synovial tissue lining the knee joint.

This creates cushioning and support within the joint environment, helping reduce pain and improve movement.

Clinical studies have demonstrated sustained improvements in symptoms for many patients over several years following a single injection.

Benefits of Arthrosamid

• One-off treatment
• Long-lasting pain relief
• No surgery required
• Quick recovery
• Effective for moderate to advanced knee osteoarthritis

Arthrosamid is particularly attractive for patients looking for a longer-term solution before considering knee replacement surgery.

Which Treatment is Right for Me?

Every patient is different…. The most appropriate treatment depends upon:

• Age
• Severity of osteoarthritis
• Activity levels
• Previous treatments
• Clinical examination findings
• Imaging results

Our Sports Medicine team will undertake a comprehensive assessment and discuss all available options before recommending the most suitable treatment pathway.

We believe in delivering the right treatment for the right patient at the right time.

Frequently Asked Questions

Are regenerative medicine injections painful?

Most patients experience minimal discomfort during treatment. Ultrasound guidance allows accurate and efficient delivery of the injection.

How long does recovery take?

Recovery varies depending on the treatment performed, but most patients can return to normal daily activities within a few days.

Can regenerative medicine prevent knee replacement surgery?

No treatment can guarantee avoidance of surgery. However, regenerative therapies may help reduce symptoms, improve function, and potentially delay the need for joint replacement in appropriate patients.
