Ostenil® Plus Injections for Knee Arthritis: Everything You Need to Kn
If you've been told you have knee arthritis, you've probably started looking at ways to reduce your pain, improve your mobility and hopefully delay surgery.
One treatment that's becoming increasingly popular is Ostenil® Plus.
At Revive Physio in Mosley Common, I regularly see people searching for alternatives to repeated steroid injections or wanting to delay knee replacement surgery.
This guide explains exactly what Ostenil Plus is, how it works, who it's suitable for and whether it may be the right treatment for you.
What Is Ostenil® Plus?
Ostenil Plus is a hyaluronic acid injection designed to improve the lubrication and cushioning inside an arthritic joint.
Hyaluronic acid is a naturally occurring substance already found within healthy joints. It acts like a lubricant and shock absorber, allowing the joint surfaces to move smoothly.
In people with osteoarthritis, the quality and quantity of hyaluronic acid gradually reduce. As a result, joints become stiffer, movement becomes more painful and everyday activities can become increasingly difficult.
Ostenil Plus replaces some of this lost lubrication, helping the joint move more comfortably.
Unlike steroid injections, it doesn't simply reduce inflammation — it aims to improve the environment within the joint itself.
What Makes Ostenil Plus Different?
Ostenil Plus contains:
High-quality hyaluronic acid
Mannitol, a naturally occurring antioxidant
The addition of mannitol helps protect the hyaluronic acid from breaking down too quickly inside the joint.
This means the treatment may remain effective for longer than hyaluronic acid alone.
Which Joints Can Ostenil Plus Treat?
Although most commonly used for knee osteoarthritis, Ostenil Plus may also be suitable for:
Shoulder arthritis
Hip arthritis (under ultrasound guidance)
Thumb arthritis
Finger arthritis
Ankle arthritis
Some other joints following assessment
The correct treatment depends on your symptoms, examination findings and imaging where appropriate.
How Does Ostenil Plus Work?
Rather than masking pain, Ostenil Plus works by improving how the joint functions.
Potential benefits include:
✔ Improving joint lubrication
✔ Reducing friction between joint surfaces
✔ Improving shock absorption
✔ Reducing stiffness
✔ Improving movement
✔ Helping reduce pain
Many people notice that walking, climbing stairs, standing from a chair and exercising become much more comfortable.
How Long Does Ostenil Plus Take to Work?
Unlike steroid injections, the effects are not usually immediate.
Most people begin noticing improvement within 2 to 6 weeks, although some experience relief sooner.
The benefits often continue to develop during the first few weeks after treatment.
How Long Does It Last?
Everyone responds differently.
Many patients experience improvement for 6 to 12 months, while some report benefits lasting even longer.
Factors affecting how long it lasts include:
Severity of arthritis
Activity levels
Body weight
Muscle strengthrn more
Overall joint health
Combining injections with physiotherapy and strengthening exercises often provides the best long-term results.
Why Choose Ostenil Plus Instead of a Steroid Injection?
Both treatments have their place, but they work differently.
Steroid injections
Often provide faster pain relief
Reduce inflammation
May be useful during painful flare-ups
Effects can wear off after several weeks or months
Repeated injections may not be recommended
Ostenil Plus
Supports joint lubrication
May improve movement as well as pain
Often provides longer-lasting symptom relief
Can be repeated if appropriate
Delays the need for surgical intervention
Does not carry the same concerns regarding repeated steroid exposure
The most appropriate treatment depends on your symptoms, goals and stage of arthritis.
Can Ostenil Plus Delay Knee Replacement?
For many people, yes.
While Ostenil Plus cannot reverse arthritis or regrow cartilage, it can significantly reduce symptoms and improve quality of life.
Many patients are able to remain active, continue exercising and postpone knee replacement surgery.
For others, it provides valuable pain relief while waiting for surgery.
Who Is Suitable?
Ostenil Plus may be appropriate if you:
Have mild to moderate osteoarthritis
Have ongoing joint pain despite physiotherapy
Want to remain active
Wish to delay surgery
Prefer to avoid repeated steroid injections where appropriate
A detailed assessment helps determine whether you're likely to benefit.
Who Shouldn't Have Ostenil Plus?
Treatment is not suitable for everyone.
It is generally avoided if you have:
An active infection in or around the joint
Broken or infected skin at the injection site
A known allergy to any ingredient within Ostenil Plus
Significant swelling requiring alternative treatment first
Pregnancy and breastfeeding should always be discussed before treatment.
A full medical history will be taken before any injection is offered.
Are There Any Side Effects?
Most people tolerate Ostenil Plus extremely well.
Temporary side effects may include:
Mild discomfort after the injection
Temporary swelling
Warmth around the joint
Bruising
These symptoms usually settle within a few days.
Serious complications such as infection are rare but every injection carries a small risk, which will be discussed before treatment.
Why Combine Ostenil Plus with Physiotherapy?
The best results rarely come from an injection alone.
Improving strength, movement, balance and joint control helps reduce the load placed on the joint and can maximise the benefits of treatment.
At Revive Physio, every injection appointment includes advice tailored to your condition, helping you get the most from your recovery.
