Knee injections can help relieve pain, reduce stiffness, and improve mobility in people with osteoarthritis and other knee joint conditions, allowing some patients to delay or avoid surgery. At our clinic, we offer a range of treatment options, including Arthrosamid, hyaluronic acid injections (Biolevox and Durolane), cortisone injections, and PRP (platelet-rich plasma) therapy. Arthrosamid is an innovative hydrogel injection that cushions the knee joint and may provide longer-lasting pain relief than some traditional hyaluronic acid (gel) injections. To maximise accuracy and safety, every knee injection is performed under ultrasound guidance, ensuring the medication is delivered precisely into the joint.
If knee pain is affecting your daily life, knee injections may help reduce discomfort and improve movement without the need for surgery. At Alton Pain Clinic in Hampshire, we offer a full range of injections for the knee joint, from established treatments such as cortisone and hyaluronic acid, through to newer options like Arthrosamid. Every treatment is carried out by an experienced clinician using ultrasound guidance, so you can be confident the injection is placed precisely where it’s needed.
What Are Knee Injections?
Knee injections are treatments delivered directly into or around the knee joint to relieve pain, reduce inflammation, or improve joint lubrication. They’re most commonly used as an injection for OA (osteoarthritis) of the knee, but can also help with other causes of joint pain, including inflammatory arthritis and soft tissue conditions around the knee.
knee injections act locally, which means they can offer targeted relief with a lower risk of the wider side effects associated with some oral medications. The right type of injection depends on your symptoms, the severity of joint changes, and what you’ve already tried.
Types of Knee Injections We Offer
Alton Pain Clinic provides a range of injections for the knee joint, tailored to your individual diagnosis and goals.
Cortisone (Steroid) Injections
Cortisone injections deliver a corticosteroid directly into the knee joint to reduce inflammation and pain quickly. They’re often used for flare-ups of osteoarthritis or inflammatory joint conditions, and can provide relief lasting from several weeks to a few months.
Hyaluronic Acid Injections (Biolevox and Durolane)
Hyaluronic acid injections, sometimes called gel injections in the knee joint, aim to supplement the joint’s natural lubricating fluid. We use Biolevox and Durolane, both established hyaluronic acid products, to help cushion the joint and ease pain associated with knee osteoarthritis.
Arthrosamid Injections
Arthrosamid is a polyacrylamide hydrogel injection that sits within the joint lining to provide long-term cushioning and support. Unlike some traditional gel for knee injections, Arthrosamid is designed as a single treatment intended to offer sustained relief. We explain how it works in more detail below.
Cingal Injections
Cingal combines hyaluronic acid with a small amount of corticosteroid in one injection, aiming to provide both the fast-acting relief of steroid and the longer-term joint support of hyaluronic acid.
PRP (Platelet-Rich Plasma) Injections
PRP uses a concentration of platelets taken from your own blood, prepared and injected back into the knee joint to support the body’s natural healing response. Some patients consider PRP alongside or as an alternative to other knee injections for pain.
What Is the New Injection for Knee Pain? Understanding Arthrosamid
Arthrosamid is one of the more recent additions to knee osteoarthritis treatment, and works differently to traditional gel shots to the knee.
Rather than being absorbed by the body over a few months, Arthrosamid integrates into the joint lining, becoming a soft, flexible support structure. This is why it’s sometimes described as a hydrogel shot rather than a standard gel injection. Many patients considering knee joint gel treatments ask how it compares to hyaluronic acid — the key difference is longevity, with Arthrosamid intended as a longer-lasting option rather than a course of repeat injections.
As with any treatment, Arthrosamid isn’t suitable for everyone, and our clinician will talk you through whether it’s an appropriate option for your knee during your consultation.
Who Might Benefit from Knee Injections?
Knee injections may be worth considering if you have:
- Osteoarthritis of the knee, with pain, stiffness or swelling
- Arthritis injections in the knee previously that provided only short-term relief
- Persistent knee pain that hasn’t improved with physiotherapy, weight management or oral medication
- A wish to delay or avoid knee replacement surgery
- Inflammatory joint conditions affecting the knee
Knee injections aren’t right for everyone, and a thorough assessment is essential before treatment. This may include a physical examination and, where appropriate, imaging to confirm the cause of your symptoms.
What to Expect During Your Appointment
All knee injections at Alton Pain Clinic are performed under ultrasound guidance. This allows the clinician to see the joint space in real time and place the injection accurately, which can improve both comfort and effectiveness compared with a landmark-guided injection.
Your appointment will typically include a brief assessment, an explanation of the recommended treatment, the injection itself, and aftercare advice before you leave.
Aftercare Following Your Knee Injection
- Rest the joint gently for 24–48 hours, avoiding strenuous activity
- Some mild swelling, warmth or bruising at the injection site is normal
- Apply a cold compress if needed to ease any discomfort
- Contact the clinic if you experience increasing redness, heat or fever, as this could indicate infection
- Follow any specific advice given by your clinician for your particular injection type

Frequently Asked Questions
What is the new injection for knee pain?
The newest widely available option is Arthrosamid, a hydrogel injection that becomes part of the joint lining to provide long-term cushioning, rather than being gradually absorbed like traditional gel injections.
How long do knee gel injections last?
This depends on the product. Hyaluronic acid injections such as Biolevox and Durolane typically provide relief for several months, while Arthrosamid is designed to offer longer-lasting support as it integrates into the joint lining.
Are knee injections painful?
Most patients experience only mild, brief discomfort during the injection. Ultrasound guidance helps the clinician place the needle accurately, which can reduce discomfort compared with a landmark-guided approach.
How many knee injections can I have?
This varies by injection type and individual circumstances. Cortisone injections are usually limited in frequency to protect the joint, while hyaluronic acid courses and Arthrosamid have their own recommended schedules. Your clinician will advise what’s appropriate for you.
