PRP Or Surgery: When To Inject And When To Operate
PRP is a reasonable alternative to surgery in chronic tendon conditions that have failed rehabilitation, and it is not an alternative to surgery for a mechanical problem or an advanced arthritic joint. The distinction is whether the tissue has failed to heal, which regenerative treatment can address, or whether the structure is damaged or worn out, which it cannot. Getting that distinction right saves both money and years.
Key points
PRP treats failed healing. It does not repair a torn structure, remove a mechanical block or replace lost cartilage.
For chronic tendon conditions such as tennis elbow, the evidence supports PRP as a genuine option before considering surgery.
For advanced bone-on-bone arthritis, a locked or mechanically blocked joint, or a complete tendon rupture, surgery is the correct answer and injection is a delay.
We do not perform surgery, so our assessment of whether you need it has no commercial pull in either direction.

The question that decides it
Ask what kind of problem you have, not which treatment you prefer.
A biological problem is one where the tissue is structurally present but has failed to heal properly. Chronic tendinopathy is the clearest example, where the tendon shows disorganised collagen and a stalled repair response rather than active inflammation or a tear. Regenerative treatment aims to restart that repair, and this is where PRP has its best evidence.
A mechanical problem is one where the structure itself is disrupted or worn away. A complete tendon rupture, a displaced meniscal tear causing locking, significant instability, a trapped fragment, or an arthritic joint that has lost its cartilage. No injection restores structure, and treating a mechanical problem biologically produces months of disappointment.
As our doctors put it, "PRP can help a tendon that has forgotten how to heal, and it cannot help a joint that has run out of cartilage." Most of the confusion in this area disappears once that line is drawn honestly.
Where PRP is a reasonable alternative to surgery
Chronic tennis elbow that has not responded to rehabilitation is the strongest case. Surgical release is a real option at that stage, and PRP has good evidence to try first, with a 2025 Level I meta-analysis of 26 randomised controlled trials finding it statistically and clinically better than corticosteroid beyond six months. Trying an injection before an operation is a reasonable sequence.
Plantar fasciitis that has persisted despite proper stretching, orthotics and load management, where pooled data show PRP producing better long-term functional improvement than corticosteroid, and where surgical release carries its own risks.
Patellar tendinopathy in an athlete who has completed a genuine loading programme, since it is among the better-supported tendon indications.
Early to moderate osteoarthritis where joint space remains and the goal is symptom control and buying good years before replacement rather than avoiding it forever. That framing is honest and it is what most people actually want.

Where surgery is the right answer
We would rather say this plainly than take a booking.
Advanced bone-on-bone osteoarthritis. When the cartilage has gone, joint replacement is the treatment that restores function, and it is a highly effective operation. An injection into that joint is money spent on a delay, and delaying too long can make rehabilitation afterwards harder.
A locked or mechanically blocked joint. If your knee catches, locks or gives way, something is physically in the way, and that is a surgical problem.
Complete tendon rupture. A ruptured Achilles or a full-thickness rotator cuff tear in the right patient needs surgical assessment, not regenerative injection.
Significant instability or structural deformity, where the mechanics need correcting.
Any red flag. Unexplained weight loss, fever with a hot swollen joint, night pain that wakes you consistently, or neurological symptoms need urgent assessment rather than an elective injection.
If any of these applies, we will tell you and help you get to the right specialist rather than treating you.
The cost comparison, honestly
Worth setting out, because the numbers are not what most people assume.
Private orthopaedic surgery in London is a substantial commitment. Knee arthroscopy commonly runs several thousand pounds, and private joint replacement runs well into five figures once the surgeon, anaesthetist, implant, hospital stay and rehabilitation are included. Recovery is measured in months, and time off work is a real cost for anyone self-employed or running a business.
Image-guided PRP at specialist central London clinics commonly costs from around £780 to £900 or more per injection including assessment, with a course of two to three taking a plan past £2,000. There is essentially no downtime, and most people return to normal activity the same day with modified loading for a short period.
So PRP is materially cheaper and less disruptive, which is exactly why it should not be chosen on those grounds alone. Two thousand pounds spent on a joint that needed replacing is worse value than twelve thousand spent on the operation that fixed it. The cheaper option is only the better one when it is also the clinically correct one.
Can you have PRP first and surgery later
Usually yes, and for the right conditions this is a sensible sequence rather than a compromise.
For chronic tendinopathy, trying PRP before surgical release does not close off the surgical option and does not generally make later surgery harder. Many patients avoid the operation. Those who do not have lost some months rather than the opportunity.
For osteoarthritis, PRP does not prevent later joint replacement and is not a reason to be refused one.
Where the sequence becomes questionable is when injections are repeated indefinitely in a joint that is clearly deteriorating, particularly in someone whose function is worsening and whose life is being limited. At that point the honest conversation is about surgery, and a clinic that keeps injecting is serving itself.
We will tell you when we think you have reached that point, which is the reason to get an opinion from somewhere that does not perform either operation.

The suitability review
Every enquiry begins with a free doctor-led suitability review rather than a booking. A GMC-registered doctor takes your history, examines the joint or tendon, reviews or arranges imaging including ultrasound, and gives one of two answers.
Approved for treatment, with the diagnosis stated, where your condition sits on the evidence, how many injections and why, what to expect at six and twelve weeks, the rehabilitation that runs alongside, and the total cost before you commit.
Or not approved, in which case we say so and explain what would serve you better, whether that is completing a proper loading programme, a steroid injection for short-term relief, or a surgical opinion with a clear explanation of why.
We decline a meaningful share of joint enquiries, and referring someone to a surgeon is a routine outcome here rather than a failure.
Why people choose The London PRP Clinic by The Wellness
We do not perform surgery, so we gain nothing from recommending it or from talking you out of it. That neutrality is worth something when every other opinion you get comes from someone who profits from one answer.
Every treatment is performed by GMC-registered doctors using image guidance, no clinician treats a patient here until they have completed 100 supervised treatments, and we teach ultrasound-guided joint PRP to doctors through our Academy. Across our work we report more than 187 five-star reviews.
We are also candid about evidence, including that the data for knee osteoarthritis are contested, which is exactly the sort of thing a clinic selling injections has no incentive to mention.

Frequently asked questions about PRP and surgery
Can PRP help me avoid surgery?
For chronic tendon conditions that have failed rehabilitation, it is a reasonable option to try first and many people avoid the operation. For mechanical problems and advanced arthritis it will not.
When is surgery the right answer?
Advanced bone-on-bone arthritis, a locked or mechanically blocked joint, complete tendon rupture, significant instability, or any red flag symptom such as fever with a hot joint or unexplained weight loss.
Does having PRP first make later surgery harder?
Generally no. Trying PRP for tendinopathy does not close off surgical options, and it does not prevent later joint replacement in osteoarthritis.
Is PRP cheaper than surgery?
Considerably, with a course commonly exceeding £2,000 against several thousand for arthroscopy and well into five figures for private joint replacement. Cost alone is a poor reason to choose it if the problem is mechanical.
How do I know if my problem is biological or mechanical?
It requires examination and imaging. Locking, catching, giving way and true instability suggest mechanical, while pain with loading in a tendon that has failed rehabilitation suggests biological.
Do you perform surgery?
No. We are a doctor-led regenerative clinic, which means our view on whether you need an operation has no commercial pull in either direction.
