Arthrosamid® Injections for Knee Osteoarthritis

Arthrosamid® Injections for Knee Osteoarthritis

Long-lasting pain relief without surgery, now available at Staffordshire Hips and Knees.

If you’re living with knee osteoarthritis (OA) and struggling with pain, stiffness, or reduced mobility, Arthrosamid® offers a clinically proven, non-surgical solution. This innovative injectable hydrogel is designed to relieve symptoms and improve quality of life, with results that can last up to five years after a single treatment.

What Is Arthrosamid®?

Arthrosamid® is a non-biodegradable polyacrylamide hydrogel injected directly into the knee joint. It integrates with the synovial tissue to cushion the joint, reduce inflammation, and improve movement.

  • One-step outpatient procedure under local anaesthetic
  • No surgery or hospital stay required
  • Clinically proven to reduce pain and stiffness
  • Long-term results , up to 5 years after a single injection

How Does Arthrosamid® Work?

Once injected into the synovial cavity of the knee, Arthrosamid® disperses within the joint fluid and binds to the synovial tissue. Over 6–12 weeks, it becomes fully integrated, softening and increasing the elasticity of the joint lining. This leads to:

  • Reduced joint stiffness
  • Decreased pain
  • Improved knee function
  • Enhanced quality of life

Clinical Results and Safety

Arthrosamid® has been extensively studied and used across Europe:

  • Up to 79% of patients under 70 reported improvement in pain
  • No serious side effects reported in trials
  • Most common side effects: mild joint pain or swelling, lasting days to weeks

Proven safe and effective for up to 5 years post-treatment

Arthrosamid® may be suitable for adults with knee OA who:

  • Are not eligible for or wish to avoid knee replacement
  • Have not responded to physiotherapy, painkillers, or hyaluronic acid injections
  • Want to reduce reliance on medication and regain mobility

  • Active skin disease or infection near the injection site
  • Joint infection or severe inflammation
  • Previous non-absorbable injectable/implant

  • Knee replacement or foreign material in the joint

Your clinician will assess your suitability during consultation.
