Platelet-Rich Plasma Injection

A platelet-rich plasma (PRP) injection is a safe and effective treatment used to speed the healing of new injuries, as well as repair chronic injuries. Platelet-rich plasma is taken from your own blood and injected under image guidance to stimulate your body to heal itself. This has been very helpful in treating chronic tendon and ligament injuries and it speeds up the healing of recent tendon or muscle injuries. It can also relieve joint symptoms, such as those associated with mild to moderate arthritis.


  • If you’re on blood thinners, we may ask that you get an international normalized ratio (INR) blood test first before the exam. Please speak to your booking coordinator for more detailed information.
  • Avoid anti-inflammatories (ibuprofen, etc.) for two weeks prior to and two weeks after your injection.
  • Do not stop taking low-dose aspirin if prescribed by your doctor.
  • You are encouraged to have a small snack one hour before your exam.
  • If you take insulin to manage your diabetes, please let your booking coordinator know. You may have some juice and a small snack after taking your insulin.
  • Wear comfortable clothing.
  • Please arrive 15 minutes prior to your appointment.


  • A technologist will go over your consent form, explain the procedure and answer any questions you may have.
  • We will take 8-30 millilitres of blood from your arm to prepare the PRP.
  • The sample is placed in a centrifuge and spun to separate the platelets from the rest of the blood components.
  • You can rest in a waiting room during this process; it takes about 5-15 minutes.
  • Your technologist will bring you into the treatment room and position you on the table where the radiologist will clean the skin and inject a local anesthetic, similar to the freezing you get at the dentist.
  • Using X-ray or ultrasound guidance, the radiologist will then inject the platelet-rich blood into the affected area using a sterile needle.
  • After being checked by our nurse post-injection, you are free to leave.


  • Please rest the injected joint or tendon for the rest of the day after your injection.
  • Avoid strenuous activity or physiotherapy for at least five days following your injection with a gradual return to activity. Please be aware of your pain and stop if it hurts too much.
  • If you are going to physiotherapy, please advise your physiotherapist that you have had this injection so they can modify your exercises if necessary.
  • If possible, please avoid anti-inflammatory medication for two weeks (such as ibuprofen – Advil). It may interfere with the effectiveness of your injection. 
  • For soft tissue injections, we advise a follow-up ultrasound at six months to assess healing.


Results from early healing are not typically appreciated until one month after the procedure, although healing and repair continue over 12 months. Some patients get complete relief that is permanent, while others have no significant effect. If an injection does not help relieve your pain, then you may need further evaluation.


We advise a single injection for soft tissues and three injections, spaced 2-4 weeks apart, for joints.

How long does the injection take to work?

As PRP promotes healing by recruiting the body’s own repair system, the process can take a few weeks. Most patients begin to notice improvement after four weeks, and should see continued improvement over months..

Are there restrictions after the procedure?

No strenuous activity for five days following your injection. Please avoid anti-inflammatories for two weeks after the injection.

How long will the injection last?

PRP injections don’t last a set number of days or weeks. The goal is to promote your body to heal itself, reversing injuries and restoring tissues permanently. For joints with cartilage damage or age-related arthritis, the peak effects (pain relief and improved function) can last between 12-24 months. If symptoms persist, a repeat PRP can be reconsidered after six months.

How many injections can I have?

This depends on your specific injury. For joints, we advise a series of three injections initially. For soft tissues (muscle, tendons, ligaments), a single initial injection is performed. The number of subsequent injections performed depends upon the severity and the type of condition being treated.

What are the side effects?

A common side effect of an injection is mild but temporary pain at the area that gradually subsides within 24-48 hours. There may also be mild bruising at the site of injection. Over-the-counter pain medications (not anti-inflammatory) or icing the area can help.
