What Are PRP Joint Injections?
Platelet-rich plasma (PRP) injections are a cutting-edge, natural treatment designed to help your body heal itself. PRP uses a small sample of your own blood, which is processed to separate and concentrate the platelets — the part of your blood rich in growth factors that promote healing and tissue repair.
When injected into an injured or painful joint, these growth factors can help reduce inflammation, stimulate tissue regeneration, and improve joint function over time.
How PRP Joint Injections Work
1. Blood Draw: A small amount of your blood is taken from your arm, similar to a routine lab test.
2. Processing: The blood is spun in a centrifuge to separate the platelet-rich plasma from other components.
3. Injection: The PRP is carefully injected into the affected joint (such as the knee, shoulder, hip, or ankle) using sterile technique — often guided by ultrasound for precision.
Benefits of PRP Injections
• Uses your own natural healing cells — no medications or foreign substances.
• Can help reduce pain and stiffness.
• May improve mobility and joint function.
• Can promote faster recovery from injury.
• May delay or reduce the need for surgery in some patients.
Conditions PRP May Help
• Osteoarthritis (especially knees and hips)
• Tendon and ligament injuries
• Sports injuries
• Chronic joint pain
• Rotator cuff or tennis elbow conditions
What to Expect
• The procedure usually takes about 30–45 minutes.
• You may experience mild soreness or swelling at the injection site for a few days.
• Most patients notice improvement within 4–6 weeks, with continued healing over several months.
• Your provider may recommend a series of treatments depending on your condition and goals.
Is PRP Right for You?
PRP is considered safe since it uses your own blood, minimizing the risk of allergic reaction or infection. It’s a great option for patients seeking a natural, regenerative alternative to medications, steroids, or surgery.
