Arthrosamid Injections in Northampton
Arthrosamid injections are a non-surgical treatment for knee osteoarthritis pain. The injection contains a polyacrylamide hydrogel that integrates with the soft tissues of the knee joint to support cushioning, lubrication, and comfort.

What Are Arthrosamid Injections?
Arthrosamid injections use a hydrogel to help reduce knee osteoarthritis pain. The hydrogel is injected into the knee joint, where it blends with the joint’s soft tissues and helps improve cushioning.
Knee osteoarthritis can cause pain, stiffness, swelling, and reduced mobility. Arthrosamid may suit selected patients who want a private, non-surgical treatment option after clinical assessment.
Who Can Arthrosamid Injections Help?
Arthrosamid injections are mainly used for knee osteoarthritis. This condition develops when the knee joint changes over time and the cartilage becomes worn, irritated, or less effective at absorbing load.
Arthrosamid may be considered for patients with:
- Knee osteoarthritis pain;
- Stiffness that affects walking or stairs;
- Reduced knee mobility;
- Discomfort during daily activities;
- Symptoms that have not settled with standard self-care;
- Interest in non-surgical knee pain treatment.
A face-to-face consultation is required before treatment. This consultation helps assess suitability and reduces the risk of inappropriate treatment.
How Do Arthrosamid Injections Work?
Arthrosamid works by placing polyacrylamide hydrogel into the knee joint. The hydrogel forms a soft layer within the joint and supports cushioning between the joint surfaces.
The treatment aims to:
- Improve joint lubrication: the hydrogel supports smoother movement inside the knee.
- Reduce friction: improved cushioning may reduce irritation during movement.
- Support mobility: reduced discomfort may help walking, stairs, and daily activity.
- Provide prolonged pain relief: the hydrogel is designed to remain in the joint tissue over time.
Arthrosamid does not work in the same way as steroid injections or hyaluronic acid injections. Your clinician will explain whether it is suitable for your knee osteoarthritis symptoms.

What Happens During the Procedure?
Arthrosamid injection treatment is minimally invasive and performed as an outpatient procedure at RAD Clinics.
The procedure usually includes:
- Preparation: the skin around the knee is cleaned and sterilised.
- Anaesthetic: local anaesthetic may be used to reduce discomfort.
- Ultrasound guidance: imaging helps identify the knee joint and guide placement.
- Injection: Arthrosamid hydrogel is injected into the knee joint with a fine needle.
- Aftercare: you receive post-procedure advice before leaving the clinic.
Most patients can return to light activities shortly after treatment, based on clinical advice.
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.
What Are the Benefits of Arthrosamid Injections?
Arthrosamid injections may help selected patients manage knee osteoarthritis pain without surgery. Suitability depends on clinical assessment.
Potential benefits include:
- Provides prolonged pain relief: Arthrosamid is designed to remain in the joint tissue and support longer-term symptom control.
- Improves joint cushioning: the hydrogel helps support the knee’s internal soft tissue environment.
- Supports knee mobility: reduced pain may help walking, stairs, and daily movement.
- Uses a minimally invasive method: the treatment uses a fine needle rather than surgery.
- Allows a shorter recovery period than surgery: many patients resume light activity after the procedure, with aftercare guidance.
Your clinician will explain expected outcomes, risks, aftercare, and alternative options before treatment.
Why Choose Ultrasound-Guided Arthrosamid Injections in Northampton?
Ultrasound-guided Arthrosamid injections in Northampton allow the clinician to place the hydrogel accurately into the knee joint. Ultrasound imaging shows the joint in real time and supports precise needle placement.
At RAD Clinics, ultrasound guidance helps:
- Target the knee joint: imaging supports accurate hydrogel delivery.
- Improve procedural precision: the clinician can see the treatment area during the procedure.
- Avoid surrounding structures: image guidance supports safer needle placement.
- Support patient comfort: precise placement can make the procedure more controlled.

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.
