Introduction
When knee osteoarthritis pain starts interfering with everyday life, doctors often suggest an injection to help manage the discomfort. The two most common options are a knee gel injection, using hyaluronic acid, and a steroid injection, using corticosteroids. Patients often ask us which is the better choice, but the honest answer is that it depends on your condition, your goals, and how your knee responds to treatment.
We work with patients at every stage of this decision, from those trying an injection for the first time to those who have cycled through steroid injections for years and are now exploring other options. In this article, we break down how each option works, what the research says, and what to consider so you can have a more informed conversation with your doctor.
What Is a Knee Gel Injection?
A knee gel injection delivers hyaluronic acid (HA), also called sodium hyaluronate, directly into the joint space. HA is a naturally occurring, gel-like substance that lubricates and cushions the knee. In osteoarthritis, this natural fluid breaks down, leading to friction, stiffness, and pain. A knee gel injection is designed to replenish this lost lubrication.
We offer two knee gel injection options built for different treatment preferences:
- Hyruan ONE, a single-injection, cross-linked HA treatment with pain relief lasting an average of 6 to 12 months
- Hyruan PLUS, a three-weekly injection series using non-cross-linked HA that closely mirrors natural joint fluid
What Is a Steroid Injection?
A steroid injection, or corticosteroid injection, works differently. Rather than replacing joint fluid, it reduces inflammation in the joint, which in turn eases pain. Steroid injections tend to act quickly, often within a few days, but their effects are typically shorter-lived compared to a knee gel injection.
Comparing Knee Gel Injection and Steroid Injection
| Steroid Injection | Hyaluronic Acid (Hyruan ONE) | |
|---|---|---|
| Speed of relief | Faster, often within a few days | Slower, typically a few weeks |
| Duration of relief | Stronger short-term effect | More sustained, longer-lasting relief |
| Safety over time | Repeated use linked to greater disease progression on imaging | Better long-term joint profile in comparison studies |
| Frequency of treatment | Limited to a few times per year | Once every 6 to 12 months |
| Cost per session | Generally lower | Higher upfront cost but cost effective for long term |
A retrospective study published in Radiology found that corticosteroid knee injections were associated with greater disease progression on imaging compared to both a control group and a hyaluronic acid group. For patients requiring ongoing osteoarthritis management rather than a one-off treatment, this is an important consideration worth discussing directly with your doctor.
Which One Should You Choose?
There is no single answer that fits every patient. A steroid injection may be more suitable if you need fast relief for an acute flare-up, such as before an important event or trip. Our HA range may be a better fit if you are managing chronic knee osteoarthritis and want an option that supports longer-term joint comfort without frequent repeat visits. We always recommend discussing your specific condition, activity level, and treatment history with your doctor before deciding.
Pairing any injection treatment with a consistent low-impact routine, such as our guide to knee exercises, can also help support your results and may reduce how often you need repeat treatment.
What Patients Often Ask Us Before Deciding
Before committing to either option, we encourage patients to think through a few practical questions: How active is your daily routine? Have previous steroid injections lost effectiveness faster than before? Are you comfortable with a treatment plan involving multiple weekly visits, as with Hyruan PLUS, or would you prefer a single session? Working through these questions with your doctor, alongside our knee pain self-assessment tool, can help clarify which path makes the most sense for you.
Frequently Asked Questions
1. Can I switch from steroid injections to a knee gel injection?
Many patients do transition between the two, especially if steroid injections are no longer providing adequate relief. Your doctor can advise on timing and suitability based on your knee’s condition.
2. Is a knee gel injection more expensive than a steroid injection?
Generally, yes, a knee gel injection tends to cost more upfront than a steroid injection. However, since it is used less frequently, the overall cost over a year may be comparable for some patients.
3. Are there side effects to this treatment?
The most commonly reported side effect is mild soreness or swelling at the injection site, which usually resolves within a day or two.
4. How many steroid injections can I have in a year?
This varies by patient, but doctors typically limit corticosteroid injections in the same joint to a few times per year to reduce the risk of cartilage or tissue damage.
5. Does this treatment work for all stages of osteoarthritis?
Knee gel injections are generally most effective for mild to moderate osteoarthritis. For advanced or severe cases, your doctor may recommend other treatment approaches alongside or instead of injections.
Conclusion
Choosing between a knee gel injection and a steroid injection is a decision best made together with your doctor, based on your knee health and lifestyle.
