C.R - Age 54
“The injection has made such as difference to our life as a family – my husband and the children have really noticed how much happier I am now that I am able to be more active. I honestly feel like I am in my mid 30s again. Since the injection, I feel like we have been living the active family life we all enjoy. We enjoyed an active summer holiday, and have walking trips planned for the Lake District and Scotland later this year. Now I feel my knees will carry me up and along the fells and mountains without any of the previous pain or discomfort. The boost Arthrosamid® has given me … well it actually feels like I could skip!”
M.W - Age 48
"I’d definitely recommend the injection. It’s helped delay knee replacement surgery and I’m back to running again. There’s a group of us from Elvet Striders due to run Chicago marathon in October 2025 and I’m hoping to run competitively there with my training partners.”


D.B - Age 65
"The effect has been truly transformative – there’s no other word for it."
R.C - Age 61
“It’s given me a level of freedom I haven’t felt in years,” he reflects. “And that, for me, is worth everything.”
N.G - Age 63
"I always tell my friends to just get on with it and not to delay seeking specialist advice, and to find out if they too might be an eligible candidate. Looking back, although my knees had been causing me problems for a while, I didn’t hang about once I’d been made aware of Arthrosamid® and I’m convinced that my prompt action at this point, played a part in my in positive reaction and ongoing and sustained recovery."

S.L - Age 68
"It’s given me back my sleep, my comfort, and the freedom to do the things I love."

J.P - Age 44
“I would just say if people were unable to do what they love then don’t delay and just get on with it. There’s evidence backing it up that it is a positive treatment, it’s not just me, there are other sports professionals turning to it. I’ve never run an ultra before so that fact that four-five months after being treated with Arthrosamid® I am confident to push myself into the realm of doing something I’ve never done before, and push my body that much, just shows to confidence in the injection.”

G.C - Age 60
"I’m still working hard to build up strength in my legs - which suffered whilst my knee was in a bad way – with regular exercise and physiotherapy. But I can honestly say that Arthrosamid® gave me a new spring in my step!"
