Arthrosamid Injections
Arthrosamid injections are an innovative treatment designed to provide long-lasting relief from osteoarthritis-related knee pain. These injections contain a hydrogel that integrates with the soft tissues of the joint, helping to cushion and lubricate the knee, thereby improving mobility and reducing discomfort. At RAD Clinics, we focus on delivering highly specialised care through advanced treatments like Arthrosamid injections, tailored to each patient’s specific needs.
Fees
- £2,370 (One knee)
- £4,500 (Both knees during same appointment)
Includes antibiotics appointment, injection, and report.
Duration
- Includes 30 mins for antibiotics appointment + 30 to 45 mins for the procedure(s).
Please note that an Arthrosamid injection appointment cannot be booked online before we triage your suitability for the procedure. A face-to-face consultation is mandatory to assess suitability and is subject to a fee of £160. The fee includes triage for the procedure and an ultrasound scan with a report.

Mode of Action of Arthrosamid Injections
Arthrosamid injections work by introducing a polyacrylamide hydrogel into the knee joint. Once injected, the hydrogel forms a soft, cushioning layer that blends with the existing tissue in the joint. This provides enhanced lubrication, reduces friction between the bones, and helps relieve the pain associated with osteoarthritis. Unlike other treatments, Arthrosamid does not degrade over time and can provide prolonged relief, making it a viable option for long-term pain management.

Procedure of Arthrosamid Injections
The procedure for Arthrosamid injections is minimally invasive and generally performed on an outpatient basis at RAD Clinics. The area around the knee is first sterilised, and a local anaesthetic may be applied to reduce discomfort. Using a fine needle, the Arthrosamid hydrogel is injected directly into the knee joint. The entire procedure typically takes only a few minutes, and patients can usually resume light activities shortly after treatment.
Ultrasound-Guided Arthrosamid Injections
At RAD Clinics, we use ultrasound-guided imaging to ensure the precise placement of Arthrosamid injections. This method allows for a more accurate delivery of the hydrogel into the affected joint, ensuring optimal distribution within the knee. Ultrasound guidance enhances the safety and effectiveness of the procedure by helping clinicians avoid surrounding structures and focus on the target area, providing a more comfortable experience for the patient.
Conditions we treat with Arthrosamid Injections
Knee Osteoarthritis
Arthrosamid is primarily used to treat knee osteoarthritis, a degenerative joint condition where the cartilage within the knee gradually wears down, leading to pain, stiffness, and reduced mobility. This treatment is particularly beneficial for patients with mild to moderate osteoarthritis who are looking for non-surgical solutions to manage their symptoms.
Benefits of Arthrosamid Injections
Arthrosamid injections offer a range of benefits for patients suffering from knee osteoarthritis, including:
- Prolonged Pain Relief: Arthrosamid’s long-lasting hydrogel helps to reduce knee pain for an extended period, offering relief beyond that of traditional injections.
- Improved Joint Lubrication: The hydrogel enhances the joint’s cushioning, reducing friction and wear on the knee’s cartilage.
- Minimally Invasive Treatment: As a non-surgical treatment, Arthrosamid injections are a less invasive alternative to more complex interventions like joint replacement surgery.
- Faster Recovery Time: Most patients can return to normal activities soon after the procedure, with minimal downtime required.
At RAD Clinics, we offer personalised care, using the latest advancements like Arthrosamid injections to help patients achieve long-term relief from knee osteoarthritis pain.
Common Questions We Hear From Patients
Where can I get Arthrosamid injection?
Arthrosamid injections are available at RAD Clinics' three locations: Milton Keynes, Aylesbury, and Northampton. Our team of experienced professionals will guide you through the process to ensure you receive the best care for your knee pain. Visit your nearest clinic today.
What is the new injection instead of knee replacement?
Arthrosamid is a non-surgical hydrogel injection used to manage pain associated with knee osteoarthritis, but it does not replace knee replacement surgery for everyone. RAD Clinics assesses suitability before treatment, particularly for patients seeking a non-surgical option.
When will Arthrosamid be available on the NHS?
Arthrosamid is not currently routinely available on the NHS, and there is no confirmed date for NHS availability. NICE has not selected Arthrosamid for technology guidance because it considered the available evidence insufficient for evaluation.
Who offers the best priced Arthrosamid injections in the UK?
RAD Clinics offers Arthrosamid injections starting at £2,290 for one knee, which is competitive compared to other UK clinics. Prices vary, so compare all fees before booking. A face-to-face consultation is required to assess suitability, costing £160, which includes triage and an ultrasound scan. Online booking is not available before this assessment.
What are the best knee injections for osteoarthritis?
Knee injections for osteoarthritis include corticosteroids, hyaluronic acid and polyacrylamide hydrogel such as Arthrosamid. Treatment choice depends on the severity of osteoarthritis, symptoms, previous treatments, clinical findings, and individual suitability.
Does Arthrosamid work for bone-on-bone osteoarthritis?
Arthrosamid treats symptoms associated with knee osteoarthritis, including advanced joint degeneration, but it does not restore lost cartilage or reverse bone-on-bone changes. Suitability requires clinical assessment because outcomes vary and current evidence does not establish Arthrosamid as appropriate for every patient.
