Advanced Non-Surgical Knee Arthritis Treatment Now Available at Pro Sports Medicine
Patients across Cardiff, South Wales and the South West can now access one of the most innovative non-surgical treatments available for knee osteoarthritis through the Regenerative Medicine Clinic at Pro Sports Medicine.
In partnership with Consultant Orthopaedic Surgeon Mr Andrew Miller, Pro Sports Medicine is proud to offer Arthrosamid® Hydrogel Injections — an advanced treatment designed to provide long-lasting pain relief and improved mobility for patients suffering with knee osteoarthritis.

Mr Miller became the first clinician in Wales to offer Arthrosamid®, helping to bring this pioneering treatment option to patients seeking an alternative to repeated injections or early knee replacement surgery.
A New Era in Knee Osteoarthritis Treatment
Knee osteoarthritis remains one of the most common causes of pain, stiffness and reduced mobility in adults.
Many patients experience significant limitations with walking, exercise, golf, gardening, work activities and day-to-day life. Traditional treatment options often include physiotherapy, pain medication, corticosteroid injections and, eventually, knee replacement surgery.
However, a significant number of patients fall into the gap between conservative management and surgical intervention.
Arthrosamid® has been developed specifically for this group of patients.
Unlike temporary injectable treatments, Arthrosamid® is a non-degradable hydrogel implant that integrates within the synovial lining of the knee joint, providing cushioning, reducing inflammation and helping to improve joint function over the long term.
What is Arthrosamid®?
Arthrosamid® is an innovative hydrogel injection consisting of 97.5% water and 2.5% cross-linked polyacrylamide.
Following injection into the knee joint, the hydrogel becomes incorporated within the synovial membrane where it helps cushion the joint and improve the internal joint environment.

Clinical studies have demonstrated significant reductions in knee pain alongside improvements in mobility, function and quality of life following a single treatment. Evidence has shown benefits can extend for multiple years after injection.
First Clinician in Wales to Deliver Arthrosamid®
Consultant Orthopaedic Surgeon Mr Andrew Miller has been at the forefront of introducing Arthrosamid® treatment in Wales.
With specialist expertise in knee conditions, osteoarthritis and joint preservation treatments, Mr Miller has helped pioneer access to this advanced injection therapy for patients across South Wales.
Speaking about the treatment, Mr Miller described Arthrosamid® as an exciting new development in osteoarthritis management and highlighted the encouraging improvements many patients have experienced in pain reduction and function following treatment.
His work in early arthritis research and joint preservation aligns closely with the philosophy of Pro Sports Medicine — focusing on evidence-based treatments designed to help patients remain active, improve function and potentially delay surgical intervention.

Why Patients Are Seeking Alternatives to Knee Replacement Surgery
While knee replacement surgery remains highly successful for severe arthritis, many patients are searching for treatment options that may help them stay active and delay surgery for as long as possible.
This is particularly relevant for:
-
Active adults
-
Recreational athletes
-
Golfers
-
Runners
-
Individuals in physically demanding occupations
-
Patients with early to moderate osteoarthritis
Arthrosamid® offers a minimally invasive treatment that can be performed under local anaesthetic as an outpatient procedure without the recovery associated with major surgery.
Long-Lasting Knee Pain Relief
One of the most exciting aspects of Arthrosamid® is its longevity.
Unlike treatments that are absorbed by the body over time, Arthrosamid® remains integrated within the synovial tissue of the knee.
Emerging clinical evidence has demonstrated sustained reductions in pain and improvements in knee function years after a single injection, making it one of the most promising developments in non-surgical knee osteoarthritis treatment.
