Every major joint, one standard of care.
Pain in a joint rarely has a single cause, so each visit starts with an assessment of the joint, the imaging and your history. The injection is chosen after that, never before.
Knee
Osteoarthritis, fluid on the knee, bursitis and meniscus pain.
Knee arthritis · Knee effusion · Patella bursitis · Meniscus issues · Baker’s cyst
Shoulder
Frozen shoulder, impingement and rotator cuff pain.
Frozen shoulder · Rotator cuff injuries · Impingement · Bursitis
Hip
Hip arthritis and the tendon and bursa pain around it.
Hip arthritis · Trochanteric bursitis · Labral issues
Elbow
Tennis elbow and other overuse pain.
Tennis elbow · Olecranon bursitis · Elbow arthritis
Hand & wrist

Ankle & foot
Heel pain, Achilles problems and arthritis of the ankle and big toe.
Plantar fasciitis · Achilles tendonitis · Ankle arthritis · Big toe arthritis
Five treatments, one way of choosing between them.
There is no best injection, only the right one for a particular joint and diagnosis. Here is what each does and who it tends to suit.
A single-injection hydrogel for knee osteoarthritis
A non-biodegradable polyacrylamide hydrogel that integrates with the lining of the knee to cushion the joint. It does not rebuild cartilage, and it is considered only after an assessment.
Tends to suit
- Knee osteoarthritis that has not improved enough with physiotherapy or pain relief
- People who want a non-surgical option before considering knee replacement
- Course
- One injection
- Evidence
- Follow-up to 5 years
- Joint
- Knee
Knee osteoarthritis that injections keep coming back to?
Arthrosamid® is a one-off hydrogel injection for suitable patients. Dr Abbas explains how it is placed and what to expect.
- One injection
- Given in a single ultrasound-guided appointment of around 30–45 minutes.
- Stays in place
- A non-biodegradable hydrogel that integrates with the joint lining rather than being absorbed.
- Confirmed first
- Suitability is decided at consultation. It does not rebuild cartilage, and results vary.
Experience you can trust
With experience comes precision.
Dr Abbas has performed an extensive number of Arthrosamid® injections, placing him among a small number of UK doctors with this depth of experience in Arthrosamid® knee treatment.
What is Arthrosamid®? A non-surgical treatment for knee osteoarthritis: a polyacrylamide hydrogel given as a single injection, designed to provide long-lasting pain relief and improved mobility. For many patients it is an option to consider before knee replacement.

Why we never inject blind
Landmark injections rely on estimation. Ultrasound lets the doctor see the needle, the joint and the structures around it as it happens.
- Accuracy
- Medication reaches the joint or tendon it is meant for, not the tissue beside it.
- Safety
- Nerves and blood vessels are visible, so they can be avoided.
- Comfort
- Fine needles, local anaesthetic where needed, and a short appointment.
- Precision
- Guided injections are widely considered more accurate than blind ones.
