Private Arthosamid Injections in Northwood

Arthrosamid® is a cutting-edge, non-surgical treatment for knee osteoarthritis. It involves a single injection of a non-biodegradable hydrogel directly into the knee joint, performed under ultrasound guidance. The hydrogel cushions the joint, reduces pain, and improves mobility—often with results lasting up to three years.

This treatment is ideal for patients with moderate to severe knee osteoarthritis who haven’t responded to lifestyle changes, physiotherapy, or medication. It’s also a valuable option for younger patients wishing to delay knee replacement surgery.

• Noticeable pain relief and improved mobility within four weeks
• Minimally invasive with a quick recovery
• Long-lasting effects—up to three years from a single injection
• May delay or reduce the need for knee replacement surgery
• Low risk of side effects or complications

Initial Consultation
You’ll meet with one of our orthopaedic consultants to discuss your symptoms, medical history, and treatment goals. Imaging such as X-rays or MRIs may be arranged to assess your condition.


The Procedure

• Takes around 15 minutes
• Performed under local anaesthetic
• Guided by ultrasound for precision
• You can go home the same day

Recovery
Most patients resume normal activities within a few days. Your consultant will provide tailored aftercare advice.

It may not be suitable if you:

• Are pregnant or breastfeeding
• Have an active infection in or around the knee
• Have had recent knee surgery or uncontrolled diabetes
• Are on blood thinners or have bleeding disorders

Your consultant will assess your suitability during your consultation.

If Arthrosamid® isn’t suitable, we also offer:

• Physiotherapy and lifestyle support
• Steroid or hyaluronic acid injections
• Platelet-rich plasma (PRP) therapy
• Autologous Protein Solution (APS)
• Partial or total knee replacement surgery

Costs vary depending on your individual needs, with treatment from £2,739 for one knee and £5,436 for both knees. For a personalised quote or to book a consultation, you can call us or book online. We work with all major UK health insurers.

At Bishops Wood Hospital, your Arthrosamid® injection is carried out as a day case procedure, meaning you won’t need to stay overnight. Once you feel comfortable, you’ll be able to leave the hospital the same day.

What to Expect After the Injection

• Mild Discomfort: As the local anaesthetic wears off, you may experience some mild discomfort in your knee. This is normal and usually short-lived. You can take over-the-counter pain relief such as paracetamol or ibuprofen if needed.

• Swelling: Some mild to moderate swelling around the injection site is common. This should gradually subside over the next few days.

• Mobility: You’ll be able to walk and carry out most daily activities straight away. However, we recommend avoiding strenuous exercise, heavy lifting, or high-impact activities for a few days to allow your knee to settle.
  
  

Driving and Transport

Please do not drive for at least 24 hours following your injection. We advise arranging for a friend or family member to collect you. If needed, our team can help organise a taxi service for your journey home.


Returning to Work

You can return to work as soon as you feel ready, depending on the nature of your job. If your role involves physical activity, your consultant may advise a short period of rest.

At Bishops Wood Hospital, your safety and comfort are our top priorities. While Arthrosamid® injections are generally very safe and well-tolerated, as with any medical procedure, there is a small risk of side effects or complications.

Before your treatment, your consultant will take time to explain all potential risks and answer any questions you may have. We believe in fully informed care, so you can make the best decision for your health.


Possible Side Effects

• Pain or Swelling at the Injection Site

This is the most common side effect and typically settles within a few days. Over-the-counter pain relief such as paracetamol or ibuprofen can help manage any discomfort.

• Joint Stiffness or Tenderness

Some patients may experience temporary stiffness or tenderness in the knee following the injection. This usually improves on its own.

• Baker’s Cyst

In rare cases, a fluid-filled swelling known as a Baker’s cyst may develop behind the knee. It often resolves without treatment but may require further care if persistent.

• Allergic Reaction

Although uncommon, allergic reactions to the hydrogel or local anaesthetic can occur. Our clinical team is fully prepared to manage any allergic response immediately and safely.

• Joint Infection

Very rarely, an infection may develop in the joint. This is a serious but treatable complication, typically managed with antibiotics.

Is the Arthrosamid® injection painful?
No, the procedure is generally not painful. A local anaesthetic is used to numb the area before the injection, so while you may feel some pressure, you shouldn’t feel pain. If you do experience discomfort during the procedure, let your consultant know immediately.



How soon will I feel the effects of Arthrosamid®?
Some patients notice improvement within 24 hours, but the full benefits typically develop over four to twelve weeks. Most people report a significant reduction in knee pain within the first month after treatment.



Can I have Arthrosamid® in both knees?
Yes, Arthrosamid® can be administered in both knees if you have osteoarthritis affecting both joints. Your consultant will assess your condition and recommend the most appropriate treatment plan for you.



How long does the effect of one injection last?
Arthrosamid® is designed to provide long-term relief, with clinical studies showing benefits lasting up to three years from a single injection.



How is Arthrosamid® different from hyaluronic acid injections?
Both treatments aim to lubricate and cushion the knee joint, but there are key differences:

• Hyaluronic acid (HA) is a natural substance that is gradually broken down by the body, typically offering relief for 4–6 months.
• Arthrosamid® is a synthetic hydrogel that integrates into the joint tissue and is not broken down, providing longer-lasting relief—often up to three years.
