About 528 million

people worldwide were living with osteoarthritis in 2019; an increase of 113% since 1990.

Pain is the most common symptom experienced by patients with knee OA.

Whilst the exact cause and increasing development of knee OA pain is unclear, clinical scans and biochemical tests indicate that inflammation may contribute to both pain and disease progression.

Patient stories - Lorraine Dawkins

Paul - Age 51

"My basketball career felt over due to pain in my arthritic knee and I was about to give in to a knee replacement. After Arthrosamid®, I am pain free and on my way to the European championships as Captain of the GB Masters team."

Lorraine D - Age 60

"My knees were in constant pain, I was not eligible for surgery so was undergoing physiotherapy, in addition to taking over-the-counter pain medication, both on a regular basis. Nothing worked, and my walking and general mobility was deteriorating — I felt my general outlook was bleak, with no other options on the horizon. However, Arthrosamid® injections were almost immediately different and after just one week I was able to walk more normally again, pain was reduced by about 90% and I am confident my knee will continue to improve. I have my life back again and that is all due to this amazing new treatment."

Patient stories - Les Goldhawk

Les G - Age 66

"In addition to the improvement of my mobility problems, there has been a huge impact on my sleep. Due to the agonizing pain I had been experiencing, I was unable to sleep well. In fact, I had not slept well for over three years, which really "It was affecting my quality of life. The difference in how I feel on a daily basis is huge. It's one of the best things I've ever done."

Arthrosamid has truly changed everything, and I haven't looked back since the day I received my treatment. It has brought me back from the brink of having to stop dancing... and now, as they say, I have complete confidence that I will be able to... ...keep dancing!'

Ian - Age 52

I was unable to ski without a brace using hydraulic supports and yet, just two months after Arthrosamid® in both knees, I was on black runs again without any support — it is literally life changing.

It is important to bear in mind that there is no cure for osteoarthritis but successful treatment with Arthrosamid® may reduce or relieve your knee pain. You should also bear in mind that your knee osteoarthritis may not improve and, in some cases, may get worse.
