PRP injection for the knee: what affects the cost and what to ask before you book
A platelet-rich plasma (PRP) injection for the knee is not a single standard product, so its price depends on what is included. The assessment, the way the plasma is prepared, the use of ultrasound, the number of injections and the rehabilitation plan all play a part. This guide explains these factors and the questions that help you compare offers fairly.

The main points in 30 seconds
- PRP is considered mainly for mild-to-moderate knee osteoarthritis that persists despite standard care.
- Price depends on assessment, preparation method, ultrasound, number of injections and rehabilitation.
- Preparation methods vary between clinics, so ask how the plasma is made.
- Relief generally lasts at least a year, but results differ between people.
- The price is given after a free consultation and fixed in the contract.
What PRP is and who it is considered for
Platelet-rich plasma is a concentrate of platelets taken from your own blood. Harvard Health describes it as the most widely used orthobiologic, with knee osteoarthritis as its most extensively studied application. How exactly it relieves pain is not fully understood; it appears to relate to anti-inflammatory effects, and whether it preserves or regenerates cartilage is still being studied.
Harvard Health says PRP is recommended for people with mild-to-moderate knee osteoarthritis whose symptoms persist despite standard care such as weight loss, physical therapy and pain relievers. For severe arthritis or a misaligned joint, it suggests that knee replacement should be considered instead. Whether PRP suits you is a medical decision, and it is the first thing that shapes any quote.
The assessment comes first
Before any injection, a doctor needs to confirm what is causing your knee pain. Cleveland Clinic explains that the provider checks for swelling, soreness, range of motion, looseness of the joint and how you walk, and that a knee X-ray usually shows evidence of osteoarthritis. An MRI or CT scan is ordered in some cases to look more closely at tissues in the joint.
Cleveland Clinic adds that early treatment offers the best chance of slowing osteoarthritis and managing symptoms without surgery, which is one more reason to start with a proper diagnosis. The assessment is a real part of the service. A clinic that offers an injection without examining the knee or looking at imaging is offering a product, not treatment. Ask whether previous scans are accepted, whether new imaging would be needed and whether it is included in the quoted plan.
How the preparation and procedure affect the price
Harvard Health describes PRP as an office procedure: blood is drawn, spun in a centrifuge and the platelets are injected. Excess joint fluid is often removed first, and ultrasound guidance is usually used. Crutches may be used on the day of the procedure, with light activity for the first week and a gradual return to normal.
A review in PubMed Central points out that preparation methods vary, in how the blood is spun, whether white blood cells are included and how the platelets are activated. It says current devices concentrate platelets to 2 to 5 times baseline, and that concentrations above 2.5 times may inhibit the therapeutic effect. These details mean that two clinics offering PRP may not be offering the same preparation, so ask which system is used and how the plasma is prepared.

How many injections and how many visits
Harvard Health does not state how many injections are needed. The PubMed Central review mentions a randomised trial in which a single dose of leukocyte-filtered PRP was as effective as two injections, and lists the best injection frequency and volume among the open questions. In practice, the number of injections is set by the doctor after an assessment, and it can differ from one person to another.
This is why a per-injection figure alone says little. Ask the doctor to explain the plan from start to finish: how many injections are expected, how many visits, and what happens if you need another course after a year.
Rehabilitation and follow-up
Harvard Health describes a physical therapy session before the injection and another about two weeks after it, and states that PRP does not replace weight management or exercise. Improvement may take six weeks to three months, and relief generally lasts at least a year, sometimes longer, usually not less than six months, depending on arthritis severity, activity level and other health conditions.
The NHS calls exercise one of the most important treatments for people with osteoarthritis, whatever their age or level of fitness. A plan that includes exercise guidance and a follow-up review is worth more than a single injection with no support. Ask who will review your progress and when, and whether that review can be done online after you return home. Also ask what you should avoid in the first week, because Harvard Health advises only light activity during that time.
Insurance, evidence and realistic expectations
Harvard Health notes that most insurance plans do not cover PRP, so many patients pay themselves. The PubMed Central review describes PRP as a promising alternative that reduces pain and improves joint function, but it also points to variable preparation methods, limited long-term data and possible loss of benefit after one year.
Be wary of any promise that PRP will rebuild the joint or avoid surgery altogether. The honest message is that it is a nonoperative option with encouraging but still developing evidence. Read about the joint treatment options on our joint treatment page before your consultation.

Frequently asked questions
Why do PRP injection prices differ between clinics?
Because the offers are not identical. They can differ in the assessment, imaging, plasma preparation, ultrasound guidance, number of injections, physiotherapy and follow-up. Compare what is included, not only the headline figure, and ask for the plan in writing.
How many PRP injections do I need?
It depends on your knee and on the doctor’s assessment. Harvard Health does not state a number, and a review notes that the best frequency is still unknown. Ask the doctor to explain the expected number of injections and visits before you agree.
Is PRP covered by insurance?
Harvard Health says most insurance plans do not cover it. Check your own policy before travelling, and ask the clinic for an itemised written plan of what the price covers, so you know exactly what you are paying for.
How long does PRP relief last?
Harvard Health says relief generally lasts at least a year, sometimes longer, and usually not less than six months, depending on arthritis severity and activity. A review notes that benefit may diminish after one year. Results vary from person to person.
Can I get a price before I travel?
The price for joint treatment is given after a free consultation, which can be held online, and it is then fixed in the contract. Share your medical history and questions with the coordinator so that the doctor can prepare for your case in advance.
