The cost of a PRP or stem cell knee injection is driven mainly by the number of sessions in your protocol, the imaging and diagnostics required beforehand, and whether the treatment is combined with other therapies. Recovery is usually activity-limiting for only a few days, while any symptomatic benefit develops gradually over weeks to months rather than immediately.
If you have been searching for the price of a PRP knee injection, you have probably noticed that published figures vary widely and rarely tell you much about your own situation. That is because the honest answer depends on what your knee actually needs. This article explains what genuinely drives cost variability, what a realistic recovery timeline looks like, and how the decision process works at our two campuses in Thailand. We do not publish fixed prices in our articles, because a responsible figure can only follow a clinical assessment. Where you want the deeper mechanism and evidence picture, we point to the clinical evidence for joint regeneration in our companion article.
What drives the cost of a PRP or stem cell knee treatment?
Cost is shaped by the scope of your plan, not by a single list price. Three factors account for most of the variation between two patients with knee pain.
The first is the number of sessions. A single injection and a course of several injections are clinically different interventions, and the research on knee osteoarthritis generally favours multi-session protocols. The number your clinician recommends depends on the state of your cartilage, your symptoms and your goals, and it is the largest single driver of overall cost.
The second is the imaging and diagnostics done beforehand. A knee that has never been imaged may need weight-bearing X-rays or an MRI to confirm what is causing the pain before any treatment is planned. Where a recent scan already exists, some of this can be avoided. Our individualised diagnostic assessment is designed to order only what genuinely informs the plan.
The third is whether the knee treatment is combined with other therapies. Some patients receive PRP therapy alone; others combine it with rehabilitation, load management or, in selected cases, stem cell therapy. Each addition changes both the clinical rationale and the cost. Because these variables interact, the only accurate figure is one produced after assessment.
How long is the recovery timeline after a PRP knee injection?
For most people, the disruptive part of recovery is short. The injection itself is an outpatient procedure, and normal daily movement usually resumes within a few days.
It is common to feel some soreness, stiffness or mild swelling in the treated knee in the first 24 to 72 hours. This is an expected inflammatory response, not a complication. In a 2025 systematic review and meta-analysis of 28 randomised controlled trials covering 3,246 patients, most post-injection adverse events were transient, with 91.2% resolving spontaneously within 72 hours and no evidence of accelerated cartilage degeneration. Clinicians typically advise easing back on high-impact activity, such as running or heavy squatting, for a short period while the knee settles, and then returning to normal loading progressively. Many patients are back to routine activity, including desk work and light walking, within the first week.
When should you expect to notice a benefit, if one occurs?
Any symptomatic improvement from PRP tends to build gradually rather than arriving on the day of treatment. Realistic expectations matter here, because a slow start is normal and does not mean the treatment has failed.
In a systematic review and meta-analysis of randomised controlled trials examining the timing of effect, PRP was more efficacious than other injectable options for knee osteoarthritis pain and self-reported function at 3, 6 and 12 months of follow-up. A separate meta-analysis of 34 randomised controlled trials, comparing 1,403 knees treated with PRP against 1,426 controls, concluded that the effect goes beyond placebo and that benefits tend to increase over time. In practice this means the fairest window to judge outcome is measured in months, not days. It also means outcomes are not guaranteed; response varies with the severity of joint changes, and some patients benefit more than others.
“The most useful thing we do at the outset is set an honest timeline. A knee injection is not a switch you flip; the evidence points to benefit that accrues over months in the patients who respond, and part of our job is helping people, and their families, judge success on that realistic horizon rather than on how the knee feels the next morning.” — Dr. Natalie Lindemann, Clinical Director (Global), Holina Global
How many sessions does a knee protocol usually involve?
There is no universal number, but the research leans towards a small course of injections rather than a single one. A review of how to optimise PRP outcomes reported that a protocol of three intra-articular injections spaced roughly one to four weeks apart produced superior pain relief compared with a single injection at twelve-month follow-up.
We treat these findings as a starting reference, not a prescription. The right number for your knee depends on your imaging, your symptoms and how you respond to early sessions. Because sessions are the biggest cost driver, understanding your likely protocol is also the clearest way to understand your likely cost, which is precisely what the consultation is designed to establish.
What a Knee Consultation at Holina Clinic Involves
A knee consultation at Holina Clinic begins with assessment, not treatment. Before we propose PRP therapy or stem cell therapy, we take a full history of the knee, examine how it moves and bears load, and review or arrange the imaging needed to understand what is actually driving your pain. No treatment plan, and therefore no figure, is offered until this individualised diagnostic assessment is complete.
From that assessment we build a plan specific to your joint: whether a course of injections is appropriate, how many sessions it is likely to involve, whether diagnostics still need completing, and whether combining therapies is clinically justified. We are candid about who is a suitable candidate and who is not, and about the fact that outcomes vary between individuals.
Holina Clinic operates on-site at two campuses in Thailand, on Koh Phangan and at Khao Yai, so consultations and follow-up can be planned around whichever location suits your travel and recovery. For patients arriving from overseas, we can sequence assessment, treatment and early follow-up into a single stay. When you are ready to discuss your own knee, you can book a consultation and we will talk you through the next steps and an accurate cost estimate for your specific plan.
Helping a family member weigh up knee treatment options
Many enquiries about knee treatment come not from the patient but from an adult child or partner helping a relative decide. If that is you, the questions worth asking on their behalf are practical ones: has the knee been properly imaged, how many sessions is the recommended course, what does the first week of recovery require in terms of help at home, and what is the realistic window before any benefit should be judged.
These are also the questions that determine cost, so asking them clarifies both the clinical and the financial picture at once. For older relatives in particular, the logistics of a short course of outpatient sessions, and the modest recovery each involves, are usually easier to plan than the alternative of ignoring a painful knee. We are happy to speak with a family member who is coordinating care, provided the patient consents, and to set out the timeline so that everyone shares the same expectations.
Frequently asked questions
How much does a PRP knee injection cost at Holina Clinic?
We do not publish a fixed figure, because an accurate cost depends on the number of sessions, the diagnostics your knee requires, and whether treatment is combined with other therapies. We provide a specific estimate after your consultation and assessment.
Why can’t you just tell me a price up front?
A responsible price follows a clinical assessment. Quoting a number before we have examined and, where needed, imaged your knee would risk being inaccurate for your situation. The consultation exists precisely to give you a figure you can rely on.
How many PRP injections will I need for my knee?
There is no single answer for everyone. Research on knee osteoarthritis generally favours a short course of injections over a single one, but your recommended number depends on your imaging, symptoms and response to early sessions.
How soon can I walk and return to work after the injection?
The injection is an outpatient procedure and normal daily movement usually resumes within a few days. Many patients return to desk work and light walking within the first week, easing back on high-impact activity for a short period.
How long until I feel a difference in my knee?
Any benefit tends to build gradually. Studies measure meaningful improvement over months rather than days, so the fair window to judge outcome is measured in weeks to months, not immediately after treatment.
Is a PRP knee injection safe?
In a meta-analysis of 28 randomised controlled trials, most post-injection effects were transient soreness or swelling, with the large majority resolving within 72 hours. As with any procedure, your clinician will discuss individual risks and suitability during your consultation.
What is the difference between PRP and stem cell therapy for the knee?
They are distinct treatments with different preparation and clinical rationale. Some patients are suited to PRP alone, others to stem cell therapy, and the decision follows your assessment. Our companion article on the clinical evidence for joint regeneration explains the mechanisms in more depth.
Will results last, or do I need repeat treatment?
Response and durability vary between individuals and with the severity of joint changes. Some patients maintain improvement for many months; others may consider repeat treatment. Your clinician will set realistic expectations for your knee.
Can you treat both knees at the same time?
This depends on your clinical picture and is decided during assessment. Treating both knees changes both the plan and the cost, which is one more reason a figure is only given after consultation.
I’m arranging this for a relative from overseas. How does that work?
With the patient’s consent we can speak with a family member coordinating care, and we can sequence assessment, treatment and early follow-up into a single stay at either our Koh Phangan or Khao Yai campus.
Which campus should we choose?
Both campuses provide the same clinical assessment for knee treatment. The choice usually comes down to travel, the length of stay you are planning, and personal preference. We can advise once we understand your logistics.
