Aftercare for Platelet Rich Plasma Joint Injection

A platelet-rich plasma (PRP) injection is a treatment that uses your own blood to help heal a joint, such as your knee, shoulder, or elbow, often for conditions like arthritis, tendonitis, or injuries. The process involves taking a small amount of your blood, concentrating the platelets (which help with healing), and injecting them into the joint. While PRP injections are generally considered safe, proper aftercare is essential to support healing and minimize risks, such as infection. Below are detailed instructions written in simple language to help you recover effectively.

 

Why Aftercare Matters

After a PRP injection, your body needs time to heal. The injection may cause some swelling or pain at first, which is normal as your body starts the healing process. Research suggests that following aftercare instructions can help reduce discomfort and lower the risk of complications, such as infection, which occurs in less than 1 in 200 cases. By resting, protecting the joint, and watching for warning signs, you can support your recovery and improve the chances of a successful outcome.

 

Aftercare Instructions

Follow these steps to take care of yourself after a PRP joint injection:

 

1. Rest and Take It Easy

• Why: The injection may cause pain or stiffness, and resting helps your joint start healing.

• What to Do:

  • Avoid strenuous activities, such as sports, heavy lifting, or intense exercise, for at least 48 hours (2 days). This gives your joint time to recover.

  • If you feel discomfort, it may last up to a week due to your body’s natural healing response. This is normal, but avoid overusing the joint during this time.

2. Protect Your Joint

• Why: Keeping weight off the joint helps it heal without extra stress.

• What to Do:

  • For the first few days, try not to put too much weight on the joint. For example, if the injection was in your knee, avoid standing or walking for long periods.

  • Your provider may recommend wearing a brace or splint for a few days to protect the joint. This is especially common for knee or ankle injections to keep the area stable.

  • Follow your providers instructions on how long to use the brace, as this may depend on the joint treated and your condition.

3. Manage Pain and Discomfort

• Why: Some pain or swelling is normal as the platelets work to heal the joint.

• What to Do:

  • Expect some soreness or discomfort for 1–7 days after the injection. This is part of the healing process and should improve on its own.

  • You can take over-the-counter pain relievers like acetaminophen (Tylenol) if needed. However, avoid anti-inflammatory medications like ibuprofen (Advil) or naproxen (Aleve) unless your provider approves, as these can interfere with the healing process triggered by PRP.

  • If pain worsens or lasts longer than a week, contact your provider for advice.

4. Watch for Signs of Infection

• Why: Although rare (less than 1 in 200 cases), infections can occur with any injection and need prompt attention.

• What to Look For:

  • Redness: The skin around the injection site looks redder than the surrounding area.

  • Warmth: The area feels warmer or hotter than the rest of your skin.

  • Drainage or Pus: Any liquid or pus comes out of the injection site.

  • Fever: Your temperature is higher than 99.5°F (37.5°C).

• What to Do:

  • Check the injection site daily for these signs.

  • If you notice any of these symptoms, call your provider immediately. Early treatment can prevent complications.

5. Follow Your Provider’s Specific Instructions

• Why: Every patient’s condition is different, and your provider may have tailored advice for you.

• What to Do:

  • Follow any additional instructions your provider provides, such as when to resume activities, start physical therapy, or attend follow-up appointments.

  • If you’re unsure about any instructions, ask your provider for clarification.

 

Expected Recovery Timeline

• Immediate Aftermath (1–2 Days): You may feel pain, stiffness, or swelling at the injection site. Rest and avoid strenuous activities during this time.

• First Week: Discomfort may continue but should gradually improve. Use a brace as recommended.

• Weeks to Months: Healing may take several weeks to show initial results, such as less pain or better joint movement. Full benefits may take months and may last 6 months to a year or longer, depending on your condition.

Risks and Considerations

• Safety: PRP injections are generally safe because they use your own blood, reducing the risk of allergic reactions. However, as with any injection, there’s a small risk of infection or other complications like bruising or nerve irritation.

• Controversy: Some studies suggest PRP may not be effective for certain conditions while others show benefits for pain relief and healing. Discuss with your provider to understand if PRP is right for you.

When to Contact Your Provider

Contact your provider immediately if you experience:

• Signs of infection (redness, warmth, drainage, or fever).

• Severe or worsening pain that doesn’t improve after a few days.

• Numbness, tingling, or weakness near the injection site, which could indicate nerve irritation.

• Any other concerns or symptoms that seem unusual.
