Does PRP Work for Arthritis and Joint Pain. What theResearch Actually Shows
Platelet rich plasma can reduce pain and improve function in knee osteoarthritis. A 2026 randomised trial inlate stage disease found it outperformed corticosteroid at six months, and meta-analyses in milder diseaseagree, though a 2021 trial in JAMA found no benefit over placebo and NICE calls the evidence limited. Tenniselbow evidence is strongest, hip and Achilles more mixed.
Key points
A 2026 randomised trial in the Journal of Orthopaedic Surgery and Research gave 90 patients with latestage knee osteoarthritis two PRP injections, a corticosteroid injection or an NSAID, and found PRPproduced greater six month improvements in pain, function, opioid use and inflammatory blood markers.
A 2023 meta-analysis of 30 studies and 2,733 patients found PRP outperformed hyaluronic acid for kneeosteoarthritis, and a 2025 meta-analysis of 28 randomised trials and 3,246 patients confirmed betterfunction. A 2021 randomised trial of 288 patients in JAMA found PRP no better than placebo, and NICEdescribes the evidence as limited in quality.
A 2024 systematic review in Cureus of five randomised hip osteoarthritis trials, 43 to 111 patients each,found significant pain and function improvement with no major adverse events, while a separate meta-analysis found no significant benefit over controls.
For tennis elbow, a 2025 meta-analysis in Clinics in Shoulder and Elbow of 26 randomised trials and 1,877patients found corticosteroid better in the first two months and PRP statistically and clinically betterbeyond six months.

What is PRP and how is it prepared for a joint injection
Platelet rich plasma is made from a small sample of your own blood, spun in a centrifuge to concentrate theplatelets, which carry growth factors involved in tissue repair and inflammation control. The concentratedplasma is then injected into or around the joint, and in newer techniques into the bone beneath the cartilage.
Because it comes from your own body, rejection and allergic reaction are rare. What varies enormouslybetween providers is preparation quality, platelet concentration, whether white blood cells are removed, andwhether needle placement is guided by ultrasound. Two clinics can both call their treatment PRP and delivermeaningfully different products, which is one reason the trial evidence is so inconsistent. The MHRA treatsPRP prepared for a medical purpose as an unlicensed medicine, with an exemption allowing doctors to prepareit for their own named patients.
At The London PRP Clinic by The Wellness, injections are image guided and doctor performed, and everypatient is diagnosed before any preparation protocol is chosen, because the right formulation depends on thejoint and the stage of disease.

How does PRP help knee osteoarthritis
Knee osteoarthritis is the most researched application of PRP, and also the most contested. The 2026 trial inthe Journal of Orthopaedic Surgery and Research randomised 90 patients aged 40 to 80 with KellgrenLawrence grade 3 to 4 disease, all on arthroplasty waiting lists, to two PRP injections a week apart, a singlebetamethasone injection, or oral aceclofenac. At six months the PRP group showed greater improvement inpain, WOMAC scores, opioid use and inflammation and cartilage turnover biomarkers, and the authorsdescribe PRP as a safe bridge therapy before surgery.
Meta-analyses point the same direction in milder disease. A 2023 analysis of 2,733 patients and a 2025analysis of 3,246 patients both found PRP outperformed hyaluronic acid or placebo on pain and function, anda 2026 systematic review in the International Journal of Rheumatic Diseases found the same against placeboacross short, mid and long term follow up.
Set against that, a 2021 randomised trial of 288 patients in JAMA found no meaningful difference betweenPRP and a saline placebo at 12 months, and NICE continues to describe the evidence as limited in quality,largely because preparation methods differ so much between studies. Both sets of findings are real. PRPappears to help a meaningful proportion of people with knee osteoarthritis, particularly when properlyprepared and image guided, but it is not a guaranteed fix.

Is there a newer technique that targets the bone rather than the joint
A June 2026 review in EFORT Open Reviews, from the orthopaedic group at Instituto Cugat in Barcelona,examined intraosseous PRP, where the injection goes directly into the bone beneath the cartilage rather thanonly into the joint space. Subchondral bone damage is now understood to play a real part in how osteoarthritisprogresses, and the review synthesised randomised, observational and laboratory evidence to May 2025.
Its conclusion was that intraosseous PRP, particularly when combined with a standard intra-articular injection,improved pain, function and imaging measures of joint structure in moderate to severe disease of the kneeand hip. The authors were clear that standardised long term trials are still needed, and the evidence base is farsmaller than for standard joint injection. It is one of the more promising directions in joint PRP research ratherthan a marketing add-on, and any provider offering it should be able to say what evidence they rely on andwhy it suits your joint.

Does PRP work for hip osteoarthritis
The hip evidence is more mixed than the knee. A 2024 systematic review in Cureus of five randomised trials,ranging from 43 to 111 patients each, found every trial reported significant pain reduction and functionalimprovement with no major adverse events. Within that positive evidence, leukocyte-poor PRP outperformedleukocyte-rich preparations, and a single injection outperformed a course of multiple injections, which runsagainst the assumption that more sessions automatically means a better result.
Against that, a separate meta-analysis of hip trials found no significant benefit over control treatment. As withthe knee, preparation method, patient selection and disease stage appear to explain much of the gap betweenpositive and negative trials. The hip is also harder to inject accurately than the knee, sitting deeper undermuscle and close to major vessels and nerves, so image guidance matters more here than anywhere else, andan unguided hip injection should be declined whatever it costs.

Can PRP treat tendon problems linked to joint pain
Tendon pain around an affected joint is common, particularly at the elbow, shoulder and heel, and the tendonevidence for PRP is generally stronger than for arthritis itself. A 2025 meta-analysis in Clinics in Shoulder andElbow of 26 randomised controlled trials and 1,877 patients with tennis elbow found corticosteroid workedbetter in the first two months but the difference sat below the minimal clinically important threshold, there wasno meaningful difference between two and six months, and PRP was statistically and clinically superior beyondsix months. A network meta-analysis of 20 trials and 1,271 patients found the same pattern.
Plantar fasciitis evidence points the same way, with a systematic review and meta-analysis finding better longterm function with PRP than corticosteroid. Achilles tendinopathy evidence is mixed, with some studiesshowing improvement over six to twelve months and others no clear advantage over control.

How many PRP injections do you actually need
There is no single correct number, and it should follow the diagnosis rather than a fixed package. Kneeosteoarthritis trials generally use one to three injections a few weeks apart, and the 2026 late stage trial usedtwo. In the hip, the strongest trials found a single injection outperformed multiple, which argues against sellinga fixed course before a doctor has actually assessed the joint.
What you do after the injection matters as much as how many you have. A 2026 meta-analysis in Disabilityand Rehabilitation pooled six randomised trials and 314 patients with knee osteoarthritis and found thatstructured exercise after PRP reduced pain more than exercise alone and more than PRP alone, in both thefirst six months and beyond. That is a larger effect than the difference between many injection protocols,which is why exercise guidance is built into the plan here rather than treated as optional.

Ten questions worth asking before any joint PRP injection
This applies whichever clinic you choose, not only ours.
Is the injection image guided, and can you see the ultrasound confirming needle placement.
Who is performing the injection, and are they a GMC-registered doctor.
Was a diagnosis made before treatment was recommended, with imaging where appropriate.
Is the PRP leukocyte-rich or leukocyte-poor, and why was that chosen for your joint.
How is your blood processed, and by whom.
How many injections are being recommended, and what is that based on.
What happens if the first injection does not help.
Is exercise or rehabilitation guidance included, or is it an injection alone.
What are the realistic chances of improvement for your stage of arthritis, not arthritis in general.
What would make you tell me not to have this treatment.
If a provider cannot answer the last question clearly, that is worth noticing.
Our doctors put it this way. PRP is a real tool for the right joint and the right patient, not a fix for every ache,and anyone who tells you otherwise before they have examined you is selling you a product rather thantreating you.
Message us on WhatsApp with your joint, your stage of arthritis if known, and any imaging you have, and adoctor will give you a straight answer before you spend anything.
What PRP does not do
PRP does not regrow lost cartilage in any way that is currently proven, and it is not a substitute for jointreplacement in advanced, bone on bone disease. It will not work for everyone, even where the evidence isstrongest, and a proportion of patients report no improvement at all. It is not routinely commissioned by theNHS for joint or tendon conditions, and private medical insurance rarely covers it, so this is almost always aself-pay treatment. Anyone expecting a guaranteed cure rather than a real chance of improvement is not agood candidate, and we would rather say so before treatment than after.

What does PRP for joint pain actually cost
Specialist central London clinics commonly charge from around £780 to £900 or more per image guided jointor tendon injection, including assessment, with a course of two to three injections taking a full plan past£2,000. Outside central London, PRP is often advertised from around £250 to £500.
The gap is rarely only about postcode. What differs is whether a doctor diagnosed you before recommendingan injection, whether needle placement is confirmed on ultrasound, whether a doctor or a therapist isinjecting, how the blood is processed, and how much clinical time sits around the injection. A lower priceusually means one of those steps has been removed, not the same treatment for less.
Care at The London PRP Clinic by The Wellness is doctor-led and priced below flagship central London rates,with your exact figure confirmed at the free suitability review once a doctor knows which joint, how manyinjections, and what preparation your case needs.
Ask about the cost for your joint on WhatsApp and we will explain what the review covers.
The free suitability review
Every enquiry here starts with a free, doctor-led suitability review rather than a booking. A GMC-registereddoctor assesses you and gives one of two answers. Either you are approved for treatment, with a clear planand realistic expectations for your specific joint and stage of arthritis, or you are not approved, with an honestexplanation of what would serve you better, whether that is physiotherapy, imaging, a different treatment, or areferral elsewhere.
We decline a meaningful share of the people who enquire. That is deliberate. A clinic that approves everyone isoptimising for bookings, not outcomes.

Frequently asked questions
Does PRP work for arthritis
For knee osteoarthritis, a 2026 randomised trial and several meta-analyses show meaningful pain and functionimprovement, sometimes outperforming steroid injections, though a 2021 trial in JAMA found no benefit overplacebo. Hip evidence is more mixed, and results depend on preparation quality, joint selection and diseaseseverity, so assessment matters more than the treatment name.
Does PRP work for bone on bone knee arthritis
A 2026 randomised trial of 90 patients with grade 3 to 4 knee osteoarthritis on replacement waiting lists foundtwo PRP injections improved pain and function more than corticosteroid or an NSAID at six months. PRP doesnot rebuild cartilage, so in advanced disease it is a bridge before surgery, not an alternative to it.
How many PRP injections do I need for knee osteoarthritis
Most knee osteoarthritis protocols use one to three injections a few weeks apart, though hip researchsuggests a single well prepared injection can outperform multiple. The right number should follow yourdiagnosis rather than a fixed package, and structured exercise afterwards adds measurable benefit.
Is PRP better than a cortisone injection
Research is mixed and joint specific. In late stage knee osteoarthritis, a 2026 randomised trial found PRPoutperformed corticosteroid at six months. In tennis elbow, corticosteroid works faster in the first two months,but PRP overtakes it from six months onward. Neither is universally better across every joint and timeframe.
How long does PRP last for joint pain
The 2026 knee trial followed patients for six months with sustained benefit, and tennis elbow research showsPRP advantages continuing beyond six months. Duration varies by joint, disease severity and preparationmethod, and is not guaranteed for every patient.
Is PRP available on the NHS for arthritis
PRP is not routinely commissioned by the NHS for joint or tendon conditions, and private medical insurancerarely covers it. Almost all patients access it as a self-pay treatment through a private clinic.
This article is for general information and does not replace a medical assessment. Speak to one of our doctors before deciding whether PRP is right for your joint.
