Chronic joint or tendon pain can be frustrating—especially when traditional options like medications or surgery don’t offer lasting relief. At Proactive Choice in Bend, Oregon, Dr. Drew Collins specializes in regenerative medicine solutions that help the body heal itself naturally. Two of the most effective and scientifically backed methods for pain relief and tissue regeneration are Platelet-Rich Plasma (PRP) Therapy and Prolotherapy.
Though both treatments are designed to stimulate natural healing, they work through different biological mechanisms. Understanding these differences can help you make the right choice for your condition and lifestyle.
What is the Difference Between PRP and Prolotherapy?
While PRP Therapy and Prolotherapy share the same goal—stimulating the body’s natural repair process—they differ in how they achieve it.
PRP Therapy uses your body’s own platelets, concentrated from a small sample of your blood, to release growth factors that accelerate healing and tissue regeneration.
Prolotherapy, on the other hand, involves injecting a mild irritant solution (usually dextrose) into damaged tissues, which triggers a localized healing response by stimulating inflammation and collagen production.
In simple terms, PRP “feeds” your cells growth factors, while Prolotherapy “wakes up” your body’s healing response by creating a controlled inflammatory reaction.
How Each Treatment Works: The Mechanisms Explained
PRP Therapy Mechanism: After drawing a small amount of your blood, it’s spun in a centrifuge to separate the platelet-rich plasma. This PRP is then injected precisely into the injured area.
Platelets release bioactive proteins that accelerate tissue repair, reduce inflammation, and promote regeneration of ligaments, tendons, cartilage, and muscles.
Prolotherapy Mechanism: Prolotherapy works by stimulating the body’s healing response through mild irritation. The injected dextrose solution increases local blood flow, brings growth factors to the area, and strengthens the connective tissue matrix. Over time, it helps stabilize joints and reduce chronic pain due to lax ligaments or tendon injuries.
Both treatments aim to restore structure and function—PRP does so by providing growth factors directly, while Prolotherapy recruits your body’s own repair mechanisms.
Conditions Treated with PRP and Prolotherapy
While both therapies are highly versatile, certain conditions respond better to one over the other:
PRP Therapy is Best For:
Tendon injuries (tennis elbow, Achilles tendinitis)
Ligament tears or sprains
Mild-to-moderate osteoarthritis
Muscle strains
Post-surgical recovery
Chronic inflammation in soft tissue
Prolotherapy is Best For:
Joint instability
Chronic ligament laxity (especially in knees, shoulders, or spine)
Low back pain and sacroiliac dysfunction
Degenerative joint disease
Repetitive strain injuries
Early arthritis
Dr. Collins encourages diagnostic imaging (like ultrasound or MRI) to determine which approach—or combination—will be most effective for your specific condition.
Procedure and Treatment Experience
Both procedures are performed in-office and take around 30–60 minutes.
During PRP Therapy, your blood is drawn, spun down, and the concentrated plasma is reinjected into the target area.
During Prolotherapy, the healing solution is injected into the affected ligaments or tendons.
Most patients experience only mild discomfort during injections. Local anesthetic may be used for added comfort, though some soreness or swelling is expected for a few days as part of the healing process.
Recovery and Downtime
After either treatment, patients are encouraged to avoid anti-inflammatory medications (like ibuprofen), as they may blunt the healing response. Light activity can usually be resumed within 24–48 hours, and most people can return to full activity within a few days. Because these therapies stimulate gradual tissue repair, results typically appear over 4–6 weeks, with continued improvement for up to 6 months.
How Many Sessions Are Needed?
PRP Therapy: 1–3 sessions spaced several weeks apart are usually sufficient, depending on the severity of injury.
Prolotherapy: Typically requires a series of 3–6 sessions, spaced 3–4 weeks apart, to achieve full benefit.
Dr. Collins designs a personalized protocol for each patient based on health history, response
rate, and activity level.
Cost of PRP vs. Prolotherapy
The cost varies based on treatment area and number of sessions. On average:
Prolotherapy tends to be more affordable, typically ranging from $250–$500 per session.
PRP Therapy involves additional lab preparation and equipment, ranging from $500–$1500 per session.
While insurance coverage is limited for both therapies, many patients find the long-term benefits—reduced pain, fewer medications, and less need for surgery—well worth the investment.
At Proactive Choice, transparent pricing and tailored care plans ensure you know exactly what to expect before starting treatment.
Risks and Side Effects
Both PRP and Prolotherapy are considered low-risk and minimally invasive, especially when performed by an experienced regenerative specialist.
Common, temporary side effects may include:
Mild swelling, soreness, or bruising at the injection site
Temporary increase in pain for 24–72 hours
Fatigue or stiffness as the tissue heals
Serious complications such as infection or nerve injury are rare when performed under sterile conditions and expert supervision.
Which Treatment Works Faster or Lasts Longer?
PRP tends to work faster because it directly delivers concentrated growth factors to the injury site. Some patients report noticeable relief within a few weeks. Prolotherapy, on the other hand, builds results gradually, often leading to more durable tissue strengthening over time.
For many patients, combining both PRP and Prolotherapy offers the best of both worlds — rapid regeneration plus long-term structural stability.
Who Is a Good Candidate?
You may be a good candidate for PRP or Prolotherapy if you:
Suffer from chronic joint or tendon pain not relieved by rest or therapy
Want to avoid surgery or long-term pain medications
Are recovering from a sports injury
Experience joint instability, ligament laxity, or early arthritis
Dr. Collins carefully evaluates each patient’s condition, age, and goals to determine whether PRP, Prolotherapy, or a combination with stem cell therapy may yield optimal results.
Frequently Asked Questions (FAQs)
1. What is the difference between PRP therapy and prolotherapy for joint or tendon pain?
PRP therapy uses a patient's concentrated platelets from their own blood to boost healing, while prolotherapy injects a sugar-based solution to stimulate the body's natural repair process. PRP delivers growth factors directly, and prolotherapy induces a mild inflammatory response to encourage tissue strengthening.
2. How do the mechanisms of PRP and prolotherapy differ?
PRP promotes tissue repair by supplying high levels of growth factors that accelerate healing. Prolotherapy works by triggering controlled inflammation to activate the body's healing, leading to new connective tissue growth.
3. Which conditions respond best to PRP? Which respond best to prolotherapy?
PRP is effective for chronic tendon injuries, early osteoarthritis, and some ligament damage. Prolotherapy is preferred for ligament laxity, certain joint instabilities, and chronic low back pain.
4. How many sessions are usually required for each treatment?
PRP typically requires 1-3 sessions spaced a few weeks apart. Prolotherapy often involves 4-6 sessions over a few months, depending on severity.
5. What is the cost difference between PRP and prolotherapy, and are these procedures covered by insurance?
PRP is usually more costly, ranging from $500 to $2000 per session, while prolotherapy costs around $150 to $400 per session. Most insurance plans do not cover either treatment.
6. What are the most common side effects or risks of PRP and prolotherapy?
Both treatments may cause temporary pain, swelling, or bruising at the injection site. PRP carries a low risk of infection using the patient’s own blood, and prolotherapy may cause a mild inflammatory reaction.
7. Which treatment works faster or provides longer-lasting pain relief?
PRP often shows faster improvement within 1-3 months and tends to offer longer-lasting effects. Prolotherapy can take 2-6 months to show benefits but may strengthen tissues over the long term.
8. Are PRP injections or prolotherapy painful?
Both procedures may cause mild discomfort during and immediately after injection. Local anesthesia can be used to minimize pain.
9. Who is a good candidate for PRP therapy or prolotherapy?
Ideal candidates have chronic joint, tendon, or ligament issues not responding to conservative therapy. People with bleeding disorders or infections may not be suitable.
10. Should I choose PRP, prolotherapy, or another regenerative option like stem cells?
Choice depends on your diagnosis and health. PRP is often favored for tendon and arthritis issues, prolotherapy for ligament problems, and stem cells for advanced or refractory cases.
11. Can these treatments help with osteoarthritis, ligament/tendon injuries, or back pain specifically?
Yes, both can be effective for mild to moderate osteoarthritis, tendon or ligament injuries, and some causes of back pain.
12. Will I require imaging (like MRI or ultrasound) before the procedure?
Imaging may be recommended to confirm diagnosis and guide the injections.
13. Is there downtime after PRP or prolotherapy injections, and when can normal activity resume?
Minimal downtime is common, with light activity allowed within 1-2 days; strenuous exercise should be avoided for 1-2 weeks.
14. How long before I see results from PRP or prolotherapy?
PRP results typically appear within 4-8 weeks, while prolotherapy effects may take 6-12 weeks.
15. Are there age limits or contraindications for receiving these treatments?
No strict age limits, but contraindications include active infection, bleeding disorders, or severe uncontrolled illnesses.
