Knee osteoarthritis is one of the most common causes of knee pain, stiffness, and reduced mobility. It occurs when the protective cartilage in the knee joint gradually wears down, leading to inflammation, pain, and difficulty with everyday activities such as walking, climbing stairs, or standing for long periods.
While severe cases may eventually require surgery, many patients can manage symptoms effectively with non-surgical treatments for knee osteoarthritis, particularly image-guided injections.
At Alton Pain Clinic, we specialise in ultrasound-guided knee injections designed to reduce pain, improve mobility, and help patients avoid or delay surgery where possible.
Why Choose Non-Surgical Treatment for Knee Osteoarthritis?
Non-surgical options are often recommended first because they:
- Reduce knee pain and inflammation
- Improve joint movement and function
- Delay the need for knee replacement surgery
- Allow faster recovery with minimal downtime
- Are performed as outpatient procedures
For many patients, knee injections for osteoarthritis provide significant symptom relief when physiotherapy or medication alone is not enough.
Best Non-Surgical Injections for Knee Osteoarthritis
1. Cortisone (Steroid) Injections
Cortisone injections for knee osteoarthritis are commonly used to reduce inflammation inside the joint.
How it works:
Corticosteroids reduce swelling and calm inflammation within the knee joint.
Benefits:
- Fast pain relief (often within days)
- Reduces inflammation and swelling
- Helps during flare-ups of knee osteoarthritis
Duration:
- Typically 2 weeks to 3 months
Best suited for short-term relief of knee pain and inflammation.
2. Hyaluronic Acid Injections
Hyaluronic acid injections help improve lubrication in the knee joint.
How it works:
Acts as a joint “lubricant” and shock absorber to improve smooth movement.
Benefits:
- Reduces stiffness
- Improves mobility
- Helps with mechanical knee osteoarthritis symptoms
Duration:
- Around 3 to 6 months
Best for mild to moderate knee osteoarthritis.
3. PRP (Platelet-Rich Plasma) Injections
PRP injections for knee osteoarthritis use concentrated growth factors from your own blood.
How it works:
Encourages natural healing processes within the joint.
Benefits:
- May improve joint function
- Reduces pain over time
- Supports tissue repair
Duration:
- Around 6 to 12 months in suitable patients
Best for early to moderate knee osteoarthritis.
4. Cingal Injection
Cingal combines hyaluronic acid and corticosteroid for both immediate and longer-term relief.
Benefits:
- Rapid pain relief
- Improved joint lubrication
- Dual-action effect
Duration:
- Weeks to several months
Ideal for patients needing both fast and sustained improvement.
5. Arthrosamid Injection
Arthrosamid is a long-lasting hydrogel injection designed to cushion and support the knee joint.
How it works:
Forms a cushioning layer within the joint to reduce friction.
Benefits:
- Long-lasting pain relief
- Improved joint comfort
- Reduced stiffness and discomfort
Duration:
- Up to 12 months or longer in suitable patients
Best for persistent knee osteoarthritis symptoms where other injections have not provided lasting relief.
Why Ultrasound-Guided Injections Matter
At Alton Pain Clinic, all injections are performed using ultrasound guidance, which allows:
- Accurate placement of medication into the joint
- Improved treatment effectiveness
- Reduced risk of complications
- Better outcomes compared to blind injections
This precision is especially important in treating knee osteoarthritis.
Which Knee Injection Is Best?
The best treatment depends on:
- Severity of knee osteoarthritis
- Level of inflammation
- Age and activity level
- Previous treatments
- Individual response
A specialist assessment helps determine the most suitable injection for each patient.
When Should You Consider Knee Injections?
You may benefit from knee injections for osteoarthritis if you have:
- Persistent knee pain
- Stiffness affecting daily activities
- Difficulty walking or climbing stairs
- Symptoms not improving with physiotherapy or medication
- Reduced quality of life due to knee pain
Do Knee Injections Cure Osteoarthritis?
No. knee osteoarthritis injections do not cure the condition.
However, they can:
- Reduce pain
- Improve mobility
- Reduce inflammation
- Delay or avoid surgery
- Improve quality of life
They are an important part of non-surgical knee osteoarthritis treatment.
