Arthrosamid® is a type of knee injection used to treat osteoarthritis of the knee, especially in people whose symptoms have not responded well to other treatments. It belongs to a group of treatments known as viscosupplements, which are designed to improve the lubrication and cushioning inside the joint.
By acting as an artificial gel-like cushion in the knee, Arthrosamid® can help reduce pain and improve mobility for some patients. In this guide, we will walk through how it works, who it may be suitable for, what the injection procedure involves, and what real patients commonly report in Arthrosamid® injection reviews.
What Is Arthrosamid®?
Arthrosamid® is an injectable hydrogel used for the treatment of knee osteoarthritis. It is placed directly into the knee joint, where it acts as a long-lasting lubricant and shock absorber.
In knee osteoarthritis, the natural joint fluid and cartilage become worn and less effective at cushioning the joint. Arthrosamid® aims to supplement this loss and create a more comfortable, smoother environment inside the knee.
It is typically considered for people who:
- Have been diagnosed with osteoarthritis of the knee
- Have not had sufficient relief from painkillers, physiotherapy, or lifestyle changes
- Are not ready for, or not suitable for, knee replacement surgery
How Does Arthrosamid® Work?
Arthrosamid® works inside the joint in several ways that can help ease symptoms of osteoarthritis.
1. Lubrication
The hydrogel in Arthrosamid® acts as an artificial lubricant inside the knee:
- It reduces friction between the cartilage surfaces of the joint
- This smoother movement can help reduce pain during everyday activities such as walking, climbing stairs, or standing up
2. Shock Absorption
Because of its gel-like consistency, Arthrosamid® also works as a shock absorber:
- It helps to cushion the joint when weight is placed through the knee
- This can reduce pressure on the cartilage and may help to slow down further wear and tear
3. Possible Inflammation Reduction
Some patients experience a reduction in swelling and stiffness after the injection. While Arthrosamid® is not a traditional anti-inflammatory drug, improving the joint environment and reducing friction may indirectly help reduce inflammation and discomfort for some individuals.
Who Is a Candidate for Arthrosamid® Injections?
Arthrosamid® is usually recommended for adults with knee osteoarthritis who:
- Have mild to moderate osteoarthritis confirmed by a healthcare professional
- Continue to have pain or stiffness despite treatments such as:
- Oral or topical medications
- Physiotherapy or exercise programmes
- Weight management or lifestyle changes
- Are looking for a non-surgical option
- Are not good candidates for knee replacement surgery or wish to delay it
A thorough assessment by a specialist is essential. They will typically review your symptoms, medical history, X-rays or scans, and other treatments you have tried before deciding whether Arthrosamid® may be appropriate.
What Happens During an Arthrosamid® Injection?
The Arthrosamid® injection procedure is usually quick and performed in an outpatient clinic. Although details may vary slightly between clinics, it generally involves the following steps:
1. Preparation
- You will be asked to lie or sit in a comfortable position with your knee supported
- The skin around the knee is cleaned and sterilised to reduce the risk of infection
- In some cases, a local anaesthetic may be used to numb the area
2. Injection
- The doctor uses a fine needle to inject Arthrosamid® directly into the knee joint space
- Ultrasound or other imaging guidance may sometimes be used to help ensure accurate placement
3. After the Injection
- You may be advised to rest the knee for a short period after the procedure
- Most people can usually go home the same day
- Your doctor may recommend avoiding high-impact activity for a short time, while allowing gentle walking and normal light activity

Arthrosamid® Injection Reviews: What Do Patients Say?
Patient experiences with Arthrosamid® can vary considerably. Like many treatments for osteoarthritis, some people report very good results, while others notice only mild improvement or no change at all. Common themes that appear in Arthrosamid® injection reviews include:
Pain Relief
- Many patients report a noticeable reduction in knee pain after the injection
- For some, pain relief appears gradually over days or weeks rather than immediately
- The degree of pain relief can range from slight improvement to a significant reduction in daily discomfort
Improved Mobility
- Patients often describe feeling more confident when walking, standing, or climbing stairs
- Some people report being able to return to light exercise or hobbies they had previously avoided because of knee pain
Duration of Relief
- For some patients, the benefits feel long-lasting
- For others, the improvement is more temporary, and symptoms may gradually return
- Multiple injections over time may be considered, depending on your doctor’s recommendations and your response to treatment
Individual Variability
One of the most important points highlighted in Arthrosamid® injection reviews is that results are highly individual. Factors such as:
- The severity of osteoarthritis
- Overall health and weight
- Activity level
- Other existing joint or medical conditions
can all influence how well a person responds to Arthrosamid®.
Factors That Can Influence Arthrosamid® Results
Several key factors may affect how effective Arthrosamid® injections are for a particular person:
Severity of Osteoarthritis
- People with mild to moderate osteoarthritis may respond better than those with very advanced “bone-on-bone” disease
- In severe cases, there may be too much structural damage in the joint for viscosupplementation alone to provide meaningful relief
Overall Health and Lifestyle
- Maintaining a healthy weight can reduce the load on the knee and help the injection work more effectively
- Regular low-impact exercise (such as walking, cycling, or swimming) may support better outcomes
- Good general health can support joint function and recovery
Adherence to Medical Advice
- Following your doctor’s guidance about activity levels, rehabilitation exercises, and follow-up appointments can also influence the end result
Possible Side Effects of Arthrosamid® Injections
Arthrosamid® injections are generally well tolerated, but as with any medical procedure, side effects are possible. Reported side effects include:
- Pain or swelling at the injection site – usually mild and short-lived
- Temporary stiffness in the knee joint after the injection
- Very rare allergic reactions – symptoms might include significant swelling, warmth, redness, or feeling unwell
If you experience severe pain, marked swelling, fever, or any symptoms that worry you after an injection, you should contact a healthcare professional immediately, as these could be signs of infection or another complication.
Cost and Insurance Coverage
The cost of Arthrosamid® injections can vary significantly depending on:
- The clinic or hospital providing the treatment
- Your country or region
- Whether any additional imaging or assessments are needed
Insurance or health plan coverage is also variable:
- Some insurers may cover part or all of the cost if the treatment is recognised in your region and medically justified
- Others may classify Arthrosamid® as a specialist or elective treatment and offer limited or no cover
It is important to:
- Check directly with your insurance provider
- Ask your clinic for a clear cost estimate in advance
This will help you understand your personal financial responsibility before going ahead.
Is Arthrosamid® Right for You?
Arthrosamid® offers a non-surgical option for people with knee osteoarthritis who are looking for pain relief and improved function when other conservative measures have not been enough.
However, it is not a cure for osteoarthritis, and it will not work the same way for everyone. Your response will depend on factors such as the severity of your arthritis, your general health, and how you manage your joint in daily life.
If you are considering Arthrosamid® after reading patient reviews and information online, the next best step is to:
- Discuss it with your GP or an orthopaedic/physical medicine specialist
- Review your diagnosis, X-rays, and previous treatments
- Weigh the potential benefits, risks, and costs in the context of your individual situation
