Relieve Pain and Achieve your Optimal Quality of Life

Getting you moving again. Arthrosamid® is a new type of treatment for knee osteoarthritis that offers patients an effective alternative to current therapies. It is a non-biodegradable hydrogel that is injected into the knee to cushion the joint and relieve pain.

Arthrosamid® is an injectable polyacrylamide hydrogel (iPAAG) single injection that is non-biodegradable and delivers long-acting pain relief for patients with knee osteoarthritis.

An Arthrosamid Injection presents a cutting-edge treatment option for knee osteoarthritis, offering patients a compelling alternative to existing therapies. Utilising an advanced non-biodegradable hydrogel technology, Arthrosamid consists of 2.5% cross-linked polyacrylamide and 97.5% water.

Upon being injected into the joint cavity, the hydrogel enhances the synovial fluid’s viscosity, thereby improving both joint lubrication and cushioning. Additionally, Arthrosamid incorporates itself into the synovium of the inner joint capsule, generating a cushion-like effect for increased comfort and functionality, mitigating pain and providing consistent, long-lasting relief with just a single administration.

At Dr SW Clinic we can treat a range of pain conditions using regenerative medicine and pain relieving injections. If you are tired of living with pain and looking for a non-surgical intervention, then DR SW Clinics could help you get back to your best, pain-free life.

How does it work?

By injecting the non-biodegradable hydrogel (iPAAG) into the affected knee joint, An Arthrosamid injection acts as a cushion to diminish the impact of the bones rubbing together. This protective cushioning helps alleviate pain, reduces inflammation, and improves overall joint function.

As a result, patients experience an enhanced quality of life and a reduction in the debilitating symptoms associated with knee osteoarthritis.

At consultation, your Consultant will be able to tell you if you are suitable. We may need an MRI or x-ray to confirm next steps.

The procedure is relatively pain free. There is some discomfort with needle insertion which we minimise by numbing the skin over the joint with a local anaesthetic. If you’re in any pain post-procedure, you will be discharged with pain relief.

Regenerative cell therapy takes between 1-2 hours. Pain reliving injections take no more than 20 minutes per joint.

All procedures are carried out under local anaesthetic so within one and three hours of your procedure, patients are typically discharged. All patients should have a chaperone (friend, family member or carer) to collect them after their procedure and remain with them on their journey home.
You are likely to feel mild pain in the joint for two to three days, however the pain can be managed with regular strength painkillers.
Post procedure, you should refrain from strenuous activity for at least two weeks.

Patients can feel immediate pain-relief. If this is not the case, do not worry, effects may take some days to come through and research has found it could take between 3-5 days.

Depending on the joint issue you present with, there may be a couple of ways to diagnose your pain and thereby find you a lasting solution.

Firstly, you will have a telephone consultation with one of our highly trained patient advisors. This patient advisor will ask you a series of pre-assessment questions to better understand your personal needs.

You will then be invited for a consultation with one of our leading experts. To better gain an understanding of the problem, the Consultant may suggest you receive an x-ray or an MRI.

What is an x-ray?
A diagnostic test that can help identify what issues are causing the pain.

What is an MRI?
A diagnostic test using a magnetic field and radio waves for a detailed image of both joint and soft tissue.

What is an ultrasound?
Typically a handheld device that provides an on the spot image of the soft tissue.

Once we’ve received the results of your diagnostic tests, our team will be able to advise you on next best steps to get you pain free.
