From HA to Hydrogels: A Practical Guide to Knee Gel Injection Cost Breakdown and What’s Included

Introduction
If you’re considering knee gel injections to manage osteoarthritis, understanding the costs involved is a crucial step. Prices can vary widely between clinics and different types of injections, which often leaves patients confused about what they’re actually paying for. With options ranging from traditional hyaluronic acid (HA) injections to newer hydrogel treatments like Arthrosamid, it’s important to know exactly what is included in the price and how treatments compare. Hydrogels themselves are not new – in fact, “hydrogels have been used in the clinic since the late 1980s with broad applications in drug delivery, cosmetics, tissue regeneration, among many other areas” (Clegg et al., 2024). This guide aims to clarify the cost components relevant to both UK and US readers and help you ask the right questions when discussing your treatment.
What Influences the Cost of Knee Gel Injections?
Several factors play a role in determining how much knee gel injections will cost. The main factor is the type of injection chosen. Traditional hyaluronic acid treatments usually require a course of several injections spread over weeks, whereas newer hydrogels like Arthrosamid are typically administered as a single injection. As one study explains, “Polyacrylamide (PAAG) hydrogel is a novel compound that has recently become available in the UK market under the name Arthrosamid, used to treat osteoarthritis” (Cole et al., 2022), highlighting its innovation in this field. Another research piece adds that “iPAAG represents a useful alternative to HA for the treatment of knee OA” (Bliddal et al., 2023), underlining its growing popularity.
Other considerations include the number of injections needed for your condition, where the treatment takes place — whether a specialist hospital, private clinic, or outpatient centre — and the skill and reputation of the consultant administering the treatment. For a fair comparison, remember that hyaluronic acid costs tend to cover multiple injections, while Arthrosamid prices usually relate to a single session.
What Does the Price Usually Cover?
When you receive a quote for knee gel injections, it’s important to know what services are typically included. Usually, these cover:
- An initial consultation with a specialist to evaluate if knee injections are appropriate for you.
- Pre-treatment imaging, which might be an X-ray, ultrasound, or MRI scan to precisely diagnose and guide your injection.
- The injection procedure itself, carried out in a clinical setting.
- A short period of aftercare, including follow-up appointments to check how you’re responding to treatment.
However, watch out for services that may not be included in the initial price. Extra follow-up visits, repeat injections if symptoms return, advanced imaging, or physiotherapy sessions often come at an additional cost. To avoid surprises, make sure to ask your provider what is and isn’t included before committing.

How to Compare Quotes and Understand Payment Options
Getting a meaningful price comparison between clinics means asking for transparent, itemised quotes. Check whether the consultation, imaging, injection, and aftercare are all covered in the price or billed separately.
Payment methods can differ widely depending on where you live. In the UK, many providers ask for a one-off payment, but some might offer monthly payment plans through private healthcare schemes. In the US, insurance coverage for knee injections can vary significantly, and clinics frequently provide payment plans to help spread costs. There’s also room to negotiate — asking about bundled packages that combine your consultation, treatment, and aftercare can sometimes lead to better value.
Typical Costs and What to Expect in the UK and US
Costs vary depending on the type of injection and geographic location. In both the UK and US, a course of traditional hyaluronic acid injections generally costs between £300 and £600 ($350–$700), which covers several sessions. A single Arthrosamid or polyacrylamide hydrogel injection is usually more expensive upfront, ranging from around £800 to £1,200 ($900–$1,500), depending on the clinic.
These higher costs may be justified by their longer-lasting benefits. As recent reviews highlight, “the past three decades have witnessed rapid advances in polymer chemistry and hydrogel fabrication, bringing many new hydrogel products to clinical studies” (Clegg et al., 2024). Additionally, “iPAAG approached superiority to HA across all participants at 52 weeks, with statistical significance in patients under 70 years old, those with normal BMI, or milder osteoarthritis” (Bliddal et al., 2023). In other words, hydrogels like Arthrosamid may provide more durable relief for certain patients. Supporting this, another study found “positive results for at least 2 years” following PAAG hydrogel injection (Cole et al., 2022).
Frequently Asked Questions
- Will my private insurance cover knee gel injections?
Insurance coverage varies a lot. While many UK and US insurers may cover hyaluronic acid, hydrogels like Arthrosamid are less often included. It’s best to check your specific plan. - Can costs vary by location?
Yes. Prices are often higher in big cities compared to rural areas, and between different clinics even within the same region. - How often will I need repeat injections?
Traditional HA courses typically last 6 to 12 months before a repeat is needed. Hydrogels like Arthrosamid are designed to last longer — sometimes two years or more.
Conclusion
Before committing to knee gel injections, make sure you understand clearly what the cost covers and what it doesn’t. Insist on transparency from your healthcare provider — this helps you balance cost, treatment benefits, and convenience. By asking the right questions and comparing detailed quotes, you can choose the best knee gel injection for your needs with confidence.
