Does PRP Work for Thumb Base and Hand Arthritis
The best trial says no. A 2025 double-blind trial of 90 patients found a single PRP injection no better than saline for thumb base arthritis at 6 months, and a 2024 meta-analysis of 10 studies found no difference between steroid and alternatives including PRP. The treatments that help are a splint, hand therapy and, when needed, surgery.
Key points
A 2025 double-blind randomised placebo-controlled trial in JBJS Open Access randomised 90 patients with painful trapeziometacarpal osteoarthritis to a single injection of PRP or saline and found no difference in pain on load at 6 months, or in pain at rest, function, range of motion or pinch strength, and concluded a single PRP injection has no short-term effect compared with placebo.
A 2024 meta-analysis in the Journal of Hand Surgery of 10 studies and 673 patients found no significantdifference in pain or function between corticosteroid injection and alternative injections, including PRP, forthumb base osteoarthritis.
The trial excluded anyone who had a corticosteroid injection into the joint within the previous 6 months,which is a useful washout figure for any patient moving between injections.
A second Swedish trial of high-concentration PRP against placebo in thumb base arthritis beganrecruiting in January 2024, so the question is being tested again with a stronger product. Until it reports,the placebo evidence is negative.

What thumb base arthritis is and who gets it
The thumb base joint, where the metacarpal meets the trapezium bone at the wrist, carries more load per unitof cartilage than almost any joint in the body, because the thumb opposes the fingers in every grip and pinch.Osteoarthritis there is common, radiographic change is present in a large share of people over 50, and it ismarkedly more common in women. The typical story is pain at the base of the thumb with pinching, turningkeys, opening jars and holding a phone, tenderness over the joint, and eventually a squared-off appearance asthe joint subluxes.
It is a small, superficial joint with a large functional cost, which is why it attracts injection treatments. A steroidinjection is easy to give and often helps for a few weeks. PRP has been offered on the strength of kneeevidence, and the trials that have tested it in the thumb directly were designed to find out whether thatborrowing was justified. The one with a placebo arm found it was not.

What the 2025 placebo trial found
The trial was run in the hand surgery department of Södersjukhuset in Stockholm and published in JBJS OpenAccess in June 2025. It enrolled 90 patients with painful trapeziometacarpal osteoarthritis and randomisedthem to a single intra-articular injection of PRP or a single injection of saline, with patients and assessorsblinded. The primary outcome was change in pain on load at 6 months, with pain at rest, the Patient-RatedWrist and Hand Evaluation, the DASH score, range of motion, key pinch and 3-finger pinch strength assecondary outcomes at 3 and 6 months.
There was no difference between PRP and placebo on the primary outcome, and none on the secondaryoutcomes either. The authors’ conclusion was that a single PRP injection has no short-term effect on pain onload compared with placebo. The trial excluded anyone with inflammatory arthritis, active hand infection,advanced scaphotrapeziotrapezoid disease, or a steroid injection into the joint within 6 months, so thepatients were the ones PRP should have had the best chance in. The group behind it has since started asecond trial using high-concentration PRP against placebo, first patient January 2024, on the argument thatthe product tested may have been too weak. That is a legitimate question. It is also the reason the honestanswer today is no rather than not yet.

What the steroid comparison adds
Trials comparing PRP with steroid in the thumb exist, and some report PRP ahead at a year. The problem is thecomparator. The 2024 meta-analysis in the Journal of Hand Surgery pooled 10 studies and 673 patientscomparing corticosteroid injection with alternatives, including PRP and hyaluronic acid, and found nosignificant difference in pain or function between them. Steroid in the thumb base gives a few weeks of reliefand then fades, and a treatment that matches it is not a treatment that works. That is the same lesson as thehip and the elbow, where PRP beats steroid at a year because steroid fails, not because PRP beats a needleand time.
A steroid injection into the thumb base is still reasonable for a specific purpose, getting through a flare or aperiod of unavoidable use, and it is cheap and available on the NHS. It should be limited in number, sincerepeated injections into a small joint carry the same cartilage concerns as elsewhere. What it should not be isthe reason a patient is sold PRP as the upgrade, because the placebo trial says the upgrade does nothing theneedle did not.

What actually helps a painful thumb base
The first-line treatment is a splint, and it is more effective than most patients expect. A thumb spica or asmaller CMC brace worn during loaded activities, and sometimes at night during a flare, unloads the joint andreduces pain in a way no injection has matched in trials. A hand therapist can fit the right one and teach jointprotection, which means changing how you grip, pinch and open things so the joint takes less load with everytask, and thenar strengthening to stabilise the metacarpal. Simple pain relief and heat help during flares.
When splinting and therapy fail and the joint is advanced, surgery is the treatment with the long track record.Trapeziectomy, removing the trapezium bone, is the standard operation, with good long-term pain relief andfunction, and there are joint-preserving and replacement alternatives for selected patients. A hand surgeon,not an injection clinic, is where a thumb that has failed conservative care belongs. Central London hasexcellent hand surgery at OneWelbeck, HCA and Cleveland Clinic London, and a doctor here will refer ratherthan inject.

Five questions before any thumb injection
Take these to whichever clinic you see, including ours.
Have I worn a properly fitted thumb splint for at least 6 weeks during loaded activities, and been taughtjoint protection by a hand therapist.
Has the joint been X-rayed, and what stage is it.
Which trial supports PRP for the thumb base specifically, and was it compared with placebo.
If the answer is a knee trial or a steroid comparison, why is the clinic recommending it against the 2025placebo trial.
If this injection does not help, who would I see next, and is a hand surgeon on the list.
Our doctors put it this way. The thumb is the joint where PRP has been tested properly against placebo andlost. Until the second trial says otherwise, the right treatment is a splint, a therapist and, when needed, asurgeon, and we will say so rather than sell you a syringe.
Message us on WhatsApp with how long the thumb has hurt, what you have tried, and any X-ray, and adoctor will give you a straight answer, including if that answer is a referral.
What PRP does not do for the hand
PRP does not improve pain on load, pain at rest, function or pinch strength in thumb base arthritis comparedwith placebo in the one trial designed to test it. It does not outperform steroid in the pooled comparisons. Itdoes not correct the subluxation of an advanced joint or remove the need for a splint. For the finger joints, thesmall joints of the fingers and the wrist, there is even less evidence, and a clinic offering PRP there isextrapolating from a thumb trial that was itself negative. PRP is not routinely commissioned by the NHS forhand conditions and private medical insurance rarely covers it.

What thumb injections cost in London, and what the money is betterspent on
Specialist central London clinics commonly charge from around £780 to £900 or more per image guided jointPRP injection including assessment, with a course of 2 to 3 taking a plan past £2,000. Image guided steroidinjections in central London are commonly quoted between £250 and £475. Outside central London PRP isadvertised from around £250 to £500.
For the thumb the reframing is simple. A custom-fitted splint and 2 or 3 sessions with a hand therapist cost afraction of one PRP injection and have evidence the injection does not. A hand surgeon’s opinion, when thejoint is ready for it, is the other purchase that changes the outcome. A PRP injection into a thumb base that theplacebo trial says will not respond costs the fee plus the months in which the splint was not worn.
Care at The London PRP Clinic by The Wellness is doctor-led and priced below flagship central London rates,but for the thumb the likely outcome of the free suitability review is a referral to hand therapy or a handsurgeon, and we would rather say that here than at the appointment.
Ask us what would help your thumb 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, which for the handmeans an unusual situation the evidence supports, with a clear plan and realistic expectations, or you are notapproved, with an honest explanation of what would serve you better, whether that is a splint and handtherapy, a single guided steroid injection for a flare, or a hand surgeon.
We decline a meaningful share of the people who enquire. For thumb and hand arthritis that share is most ofthem, and we publish this article so that fewer people pay elsewhere for what the placebo trial says does notwork.

Frequently asked questions
Does PRP work for thumb arthritis
Not in the only placebo-controlled trial. A 2025 double-blind trial of 90 patients found a single PRP injectionno better than saline for thumb base arthritis at 6 months on pain, function or pinch strength. A 2024 meta-analysis of 10 studies found no difference between steroid and alternatives including PRP.
What is the best treatment for thumb base arthritis
A properly fitted splint worn during loaded activities, joint protection and strengthening taught by a handtherapist, and simple pain relief for flares. When those fail and the joint is advanced, trapeziectomy or a relatedoperation has good long-term results. Injections give short-term relief at best.
Is a steroid injection worth having for thumb arthritis
For a flare or a specific period, yes. It gives a few weeks of relief and is cheap and available on the NHS. Itshould be limited in number, and it is not evidence that PRP would do better, since the pooled comparisonsshow no difference between steroid and PRP in the thumb.
Can PRP help arthritis in the fingers
There is even less evidence for the finger joints than for the thumb base, and the thumb trial was negative. Aclinic offering PRP for finger arthritis is extrapolating from a trial that failed. Splinting, hand therapy and arheumatology or hand surgery opinion are the evidence-based routes.
When should I see a hand surgeon for my thumb
When pain limits daily tasks despite 6 weeks of splinting and hand therapy, when the joint is visibly squared offor subluxed, when X-rays show advanced change, or when a steroid injection has stopped helping.Trapeziectomy and its alternatives have long track records and a surgeon is the right person to weigh them.
Is PRP for the hand available on the NHS
PRP is not routinely commissioned by the NHS for thumb or hand arthritis, and private medical insurancerarely covers it. Splints, hand therapy, steroid injections and surgical referral are available on the NHS, and forthe hand those are the treatments with evidence.
