What Is the New Injection for Knee Pain?

The new injection for knee pain is Arthrosamid, an advanced hydrogel treatment for knee osteoarthritis. Arthrosamid is injected directly into the knee joint, where it integrates with the synovial lining to provide long-lasting pain relief, improved cushioning, and enhanced mobility.

At Alton Pain Clinic, Arthrosamid injections are performed using ultrasound guidance, ensuring precise placement within the joint for maximum effectiveness.

What Is Arthrosamid?

Arthrosamid is a relatively new injectable treatment for knee osteoarthritis. It is a non-degradable polyacrylamide hydrogel — essentially a water-based gel that, when injected into the knee joint, integrates into the synovial membrane (the lining of the joint).

Unlike traditional hyaluronic acid injections, which are broken down and absorbed by the body over time, Arthrosamid remains in the joint and continues to provide cushioning and support. This makes it a longer-lasting option for patients with knee osteoarthritis who want sustained relief.

It received CE marking in Europe and has been available in the UK through specialist clinics since 2021.

How the New Knee Injection Works

When injected, Arthrosamid acts as a soft tissue reinforcement within the synovial membrane. Rather than simply lubricating the joint (as hyaluronic acid does), it becomes physically integrated into the synovial tissue and provides ongoing mechanical support.

The result is a reduction in pain and improved joint function. Because the hydrogel is not biodegradable, it does not need to be repeated in the way that hyaluronic acid injections do — though individual responses vary.

Who Can Benefit From Arthrosamid Injections?

Patients who may benefit include those who:

  • Have knee osteoarthritis
  • Experience persistent knee pain or stiffness
  • Are looking for long-lasting relief with a minimally invasive procedure

A consultation at Alton Pain Clinic will determine if Arthrosamid is suitable for your knee condition.

Arthrosamid Reviews

Patient feedback for Arthrosamid has generally been positive, particularly among those who had limited success with other injectable treatments. Common themes include:

  • Meaningful reduction in daily knee pain
  • Improved ability to exercise and walk longer distances
  • Reduced need for pain medication
  • A straightforward procedure with minimal downtime

 

As with any treatment, it does not work for everyone. A small proportion of patients experience no significant change in symptoms. A thorough consultation and assessment is important to determine whether Arthrosamid is appropriate for you.

What to Expect During an Arthrosamid Injection

Arthrosamid is injected directly into the knee joint under ultrasound guidance. At Alton Pain Clinic, all injections are performed with real-time imaging to ensure accurate placement.

  1. A consultation to assess your knee, review imaging, and confirm suitability
  2. Ultrasound-guided injection into the knee joint — takes around five minutes
  3. Brief period of observation
  4. Aftercare advice — gentle activity is encouraged, but high-impact exercise should be avoided for a few days

Some patients experience mild discomfort or swelling in the days following the injection. This usually settles within a week.
