Ultrasound-Guided PRP Injection in the Knee
Knee pain due to arthritis or injury can affect your ability to walk, climb stairs, sit cross-legged or stay active in daily life.
When medicines and basic physiotherapy are not enough, a PRP injection given under ultrasound guidance is a modern treatment option that can help reduce pain, improve joint function and slow degeneration — using the body’s own natural healing process.
PRP stands for Platelet-Rich Plasma, a concentration of platelets taken from your own blood, which contains important healing proteins called growth factors.
What Is PRP?
In PRP therapy, a small amount of your blood is taken and processed in a centrifuge to separate the platelet-rich layer. This concentrated plasma contains:
- Growth factors
- Anti-inflammatory proteins
- Repair enzymes
These help reduce inflammation, promote tissue healing, and improve lubrication inside the knee.
Because PRP is made from your own blood, it is natural and safe.
Why Ultrasound Guidance?
With ultrasound, the doctor can clearly see the joint and needle in real time, ensuring PRP is placed exactly where healing is needed.
Benefits of ultrasound guidance:
- Accurate placement in the joint
- Helps avoid nerves and vessels
- Better outcomes than blind injections
- Useful in obese or deformed knees
- No radiation exposure
- Real-time visual confirmation
- More comfortable and safer experience

Conditions Where PRP Helps
PRP is commonly used for:
- Knee Osteoarthritis (early and moderate stages)
- Chondromalacia patellae
- Post-traumatic cartilage damage
- Sports injuries (ligament sprain, meniscus irritation)
- Tendinitis around the knee
- Persistent pain despite medicines and physiotherapy
PRP may help delay or avoid surgery in selected patients.
How the Procedure Is Done
The procedure takes about 20–30 minutes and is done in the OPD/procedure room.
- Blood collection
A small amount of blood is taken from your arm. - Processing
The blood is placed in a centrifuge to separate the platelet-rich plasma. - Ultrasound scan
The knee is examined with ultrasound to locate the joint space. - Injection
The PRP is injected under ultrasound guidance into the knee joint using a fine needle. - Dressing
A small bandage is applied; no stitches are required.
You can walk out of the clinic soon after the injection.
After the Injection
- Mild discomfort for 1–2 days is normal.
- Avoid strenuous activities like running or squatting for a few days.
- Ice packs can be used for relief.
- Pain relief usually starts in 2–6 weeks, as natural repair takes time.
- Physiotherapy improves movement and muscle strength.
PRP is not a painkiller — it promotes healing, so effects are gradual but longer-lasting.
Benefits of PRP
Compared to steroid or pain medicines, PRP:
- Uses your own blood
- Helps repair cartilage damage
- Reduces inflammation naturally
- Improves joint lubrication
- Slows degenerative changes
- May reduce the need for repeated injections
- Helps delay surgery in early arthritis
Patients often report better mobility, reduced pain and improved daily function.
Is It Safe?
PRP injections are considered very safe, because they come from your own body.
Side effects are minimal and usually limited to temporary soreness.
Your doctor will take precautions if you have:
- Uncontrolled diabetes
- Bleeding disorders
- Recent infection
- Severe medical illness
Who Is a Good Candidate?
You may benefit if:
- Knee pain is affecting your daily activities
- X-ray/MRI shows early or moderate arthritis
- Medicines and basic physiotherapy are not helping enough
- You want to avoid or delay knee replacement
- You want a biological treatment instead of steroids
After examination and imaging, your doctor will decide if PRP is suitable.
PRP vs Steroid Injection
| Feature | PRP | Steroid |
|---|---|---|
| Source | Your own blood | Medicine |
| Effect | Healing, regeneration | Reduce inflammation |
| Duration | Long-term | Short-term |
| Best for | Early arthritis | Painful flare-up |
| Surgery delay | Yes | Limited |
Both may be used in different situations based on patient needs.
Key Takeaway
Ultrasound-guided PRP injection is a modern, safe and effective treatment for knee arthritis and chronic knee pain.
By using your body’s own healing factors and placing them exactly where they are needed, PRP helps reduce pain, improve mobility and delay the need for surgery — without hospital admission.
