If you are dealing with joint or tendon pain that will not settle down, you have probably come across PRP. You may have also been offered stem cells or peptides by a clinic promising to regrow whatever is worn out. Before you spend money on any of it, you deserve a straight answer about what platelet-rich plasma actually is, what it can and cannot do, and what it costs.
This is the honest version. Some of it is encouraging. Some of it is a reality check. All of it is meant to help you make a good decision.
What PRP actually is
PRP stands for platelet-rich plasma. We draw a small amount of your own blood, spin it in a centrifuge to concentrate the platelets, and inject that concentrate back into the injured area. Platelets carry growth factors, the signaling proteins your body already uses to begin repair. The idea is simple: deliver a concentrated dose of your own healing signals directly to the tissue that is struggling to heal on its own.
Because the injection uses your own blood, there is no risk of rejection and no foreign material involved. That is part of what makes it appealing for active people who want to avoid surgery and the recovery that comes with it.
Where PRP fits, and where it does not
PRP is not a cure-all, and any clinic that markets it that way is overselling. It tends to be most useful for specific problems:
- Chronic tendon injuries that have not healed with rest and rehab, such as tennis elbow, patellar tendon pain, and Achilles issues
- Mild to moderate joint osteoarthritis, particularly in the knee
- Certain ligament and soft-tissue injuries in athletes who want to avoid time away from their sport
PRP is less helpful for severe, bone-on-bone arthritis or for problems that genuinely need surgical repair. A torn structure that needs to be put back together will not be fixed by an injection, and you should be wary of anyone who tells you otherwise.
PRP versus stem cells and peptides
Many patients arrive having already tried, or been pitched, stem cell injections or peptide therapy. Here is the distinction that matters. PRP uses your own blood and is supported by a growing body of clinical research for tendon and joint problems. Many of the stem cell and peptide products marketed for orthopedic pain are experimental, expensive, and not well proven for these uses. Some are not what they claim to be at all.
That does not mean every alternative is worthless. It means the burden of proof matters, and your money matters. When a treatment is well studied and uses your own tissue, the risk-to-cost equation looks very different from an unproven product sold at a premium. The goal is to choose treatment based on what the evidence supports, not on what sounds the most futuristic.
What to expect during and after a PRP injection
- The blood draw. We take a small sample, similar to routine bloodwork.
- The sample is spun down to concentrate the platelets. This takes a few minutes.
- The injection. Using ultrasound guidance, the concentrate is placed precisely into the injured tendon or joint. Ultrasound matters here, because seeing the needle in real time means the treatment goes exactly where it needs to go.
- Most people go home the same day. It is normal to feel soreness or stiffness in the treated area for a few days as the healing response gets going. Many people are back to daily activity quickly, with a gradual return to harder training.
PRP is not an instant fix. It works by prompting your body to repair tissue, and that takes time. Improvement is usually gradual over several weeks, and some people benefit from more than one treatment.
What PRP costs
This is the question almost everyone has, so here is a candid answer. PRP for orthopedic conditions is typically not covered by insurance and is paid out of pocket. Pricing varies by clinic, by the area being treated, and by how many injections you need, so the most honest thing any provider can give you up front is a range, then a firm number once you have been evaluated.
What you should expect from a trustworthy clinic is transparency: a clear price before you commit, a clear explanation of how many sessions are likely, and an honest assessment of whether PRP is even the right tool for your problem. If PRP is not likely to help you, you should be told that before you pay for it.
So does PRP actually work?
For the right problem, in the right patient, the research and clinical experience are genuinely encouraging, especially for stubborn tendon injuries and earlier-stage knee arthritis. For the wrong problem, it will disappoint you. The single biggest factor in whether PRP works is an accurate diagnosis in the first place. That is why the process should always start with a proper evaluation and the right imaging, not with the injection.
The honest bottom line
PRP is a real, evidence-supported option for many joint and tendon problems, and it lets a lot of active people avoid surgery and keep doing what they love. It is not magic, it is not right for everyone, and it should never be sold to you as a guarantee. The right next step is a conversation with a physician who will look at your imaging with you, tell you honestly whether you are a candidate, and build a plan around your actual goals.
