What Is Platelet-Rich Plasma (PRP) Therapy and What Conditions Does It Treat?

PRP therapy uses a concentrated dose of your own platelets to support healing in an injured joint, tendon, or disc. It’s a regenerative option that draws on your body’s own repair signals rather than medication. Here’s what PRP therapy is, the conditions it treats, and an honest look at where the evidence stands.

Interest in regenerative options keeps growing as people look past drugs and surgery. PRP is an autologous blood extract that uses a patient’s own platelets to promote and accelerate the recovery of injured ligaments, muscles, tendons, and joints.

What Is PRP Therapy?

PRP therapy is a treatment that concentrates the platelets from a small sample of your own blood and injects them into an injured area. Those platelets carry growth factors that help calm inflammation and support tissue repair.

• A small blood draw is spun in a centrifuge to concentrate the platelets.
• The concentrated platelet-rich plasma is then injected into the target area.
• Platelets release growth factors that support healing and repair.
• Because it uses your own blood, PRP therapy has few adverse effects.
• The whole process usually takes under an hour in the clinic.
• PRP therapy is one tool within the broader field of regenerative medicine.
• It aims to support the body’s repair, not just mask a symptom.
• The right candidate depends on a careful exam and diagnosis.
• The concentrated platelet-rich plasma is what makes the injection work.
• Preparing the platelet-rich plasma takes only a quick spin in a centrifuge.

How Does PRP Therapy Work?

PRP therapy works by delivering a high concentration of platelets and their growth factors right where healing is needed. Those signals help recruit repair cells and calm the inflammation that drives pain.

• Platelets are rich in growth factors that guide tissue repair.
• Concentrating them amplifies the natural signals your body already uses.
• Injecting them at the injury focuses that repair where it’s needed.
• The growth factors help reduce inflammation around the injured tissue.
• PRP therapy uses your own biology, so rejection isn’t a concern.
• Results build gradually over weeks as tissue responds.
• A single injection or a short series may be used, based on the case.
• The goal is to support genuine healing, not a temporary numbing.
• The platelet-rich plasma is guided into place, sometimes with ultrasound.
• One well-placed injection can reach tissue that oral medication can’t.

What Conditions Does PRP Therapy Treat?

PRP therapy is used for a range of joint, tendon, and disc problems, with the strongest evidence in knee arthritis. It’s most often considered when conservative care hasn’t fully resolved the problem.

• Knee osteoarthritis is by far the most studied use of PRP therapy today.
• A meta-analysis found PRP relieved knee pain and improved function better than saline or corticosteroid.
• Tendon problems like tennis elbow and Achilles tendon issues are common targets.
• Rotator cuff strains and other soft tissue injuries are also treated with it.
• For disc-related sciatica, epidural PRP eased leg pain over 24 weeks with no adverse events in one trial.
• Mild to moderate arthritis tends to respond better than severe, bone-on-bone cases.
• Chronic tendon problems that resist rest and rehab are common candidates.
• PRP therapy directly targets the joint, tendon, ligament, or disc that’s involved.
• The best use always depends on your specific diagnosis, not a one-size approach.
• An injection is targeted, so it reaches the exact joint or tendon involved.

Is PRP Therapy Safe and Backed by Evidence?

PRP therapy has a strong safety profile because it uses your own blood, and the evidence is encouraging for some uses while still emerging for others. Honest expectations matter here.

• Because PRP is autologous, allergic and rejection risks are very low indeed.
• Studies of PRP for knee arthritis reported few adverse events overall.
• The most common side effect is short-lived soreness at the injection site.
• The evidence is strongest for knee osteoarthritis pain and function.
• For tendons and discs, results are promising but still developing.
• PRP preparation methods vary, which makes studies harder to compare.
• PRP therapy is not a guaranteed cure, and results vary by person.
• A trustworthy provider explains both the potential and the limits.
• Realistic expectations are part of good regenerative care.
• Because the platelet-rich plasma comes from you, there’s nothing foreign introduced.
• We walk you through what the research does and doesn’t yet show.

How Does PRP Therapy Fit a Broader Treatment Plan?

PRP therapy works best as one piece of a coordinated plan, not a standalone fix. Pairing the injection with rehab and hands-on care helps the healing hold.

• PRP therapy calms and supports the injured tissue.
• Physical therapy rebuilds the strength around that healing tissue.
• Chiropractic care restores the joint motion that protects it over time.
• Massage and soft tissue work ease the tension that surrounds an injury.
• Other regenerative options may fit specific arthritis cases.
• Activity guidance protects the area while it slowly heals.
• Getting out of pain is the first goal, restoring function the next.
• A coordinated care team decides where PRP therapy adds the most value.
• The injection is a boost, not a replacement for the rest of the plan.
• One injection paired with rehab tends to outlast the injection alone.

It’s used for knee arthritis, tendon problems like tennis elbow and Achilles issues, rotator cuff injuries, and some disc-related pain. The evidence is strongest for knee osteoarthritis.

Is PRP therapy safe?

It has a strong safety profile because it uses your own blood, so allergic and rejection risks are very low. Studies report few adverse events, though results vary by person.

For some, it’s a non-surgical option worth trying first, especially in mild to moderate arthritis. It doesn’t replace surgery in every case, and your exam guides the decision.

How is PRP therapy different from a steroid injection?

Steroids mainly reduce inflammation for a while, while PRP aims to support actual tissue repair using your own growth factors. In knee arthritis studies, PRP outperformed corticosteroid over time.
