Which infiltration for which pain?

Musculoskeletal pain is usually relieved with physical therapy.

In some cases, your doctor may prescribe cortisone, a viscosupplement or platelet-rich plasma (PRP) infiltration to relieve pain and complement the treatment. What are the characteristics of each of these techniques?

Infiltrations at a glance

Cortisone infiltration

What is it?

Cortisone is a powerful anti-inflammatory drug used to quickly relieve the pain associated with an acute inflammatory attack due to osteoarthritis or injury. It also reduces the need for medication and helps people get back to work.

When is it most often prescribed?
  • Tendinitis
  • Bursitis
  • Osteoarthritis
  • Arthritis
  • Epicondylitis
  • Carpal tunnel syndrome
  • Morton's neuroma
  • Epitrochleitis
What is the procedure?

Cortisone is injected into the area to be treated, sometimes under ultrasound or fluoroscopic guidance. The joint should be rested for 7-14 days following the infiltration, depending on the case (if the tendon tears, rest is longer). It causes almost no side effects. The maximum per year is 4.

How long do the effects last?

This is a short-term treatment: the effects are usually felt 24 to 48 hours after the injection. The product is eliminated from the body after four to six weeks, but the relief can last up to three months and even longer. Cortisone infiltration is not a regularly repeated treatment and should be limited to three per year per injection site.

Infiltration of a viscosupplement

What is it?

Viscosupplementation supplements hyaluronic acid, a substance found in joints and periarticular structures such as tendons and ligaments. It is primarily used to slow the breakdown of cartilage caused by osteoarthritis, but it can also help heal certain injuries.

When is it most often prescribed?
  • Joint pain related to osteoarthritis
  • Ankle ligament sprain
What is the procedure?

This product is injected under ultrasound or fluoroscopic guidance. The joint should be at rest for 7 days following the infiltration.

For tendons or ligaments, two infiltrations are sufficient (the protocol is with 2 injections).

The injection may cause local pain and slight swelling, which can be relieved by applying ice, but these side effects are rare and short-lived.

How long do the effects last?

The effects of the product may appear after a few days or even a few weeks and last for several months. For tendon and ligament injuries, one or two infiltrations are usually sufficient. As aging accentuates osteoarthritis, it is recommended to repeat the infiltration once a year.

Infiltration of platelet-rich plasma

What is it?

Platelet-rich plasma (PRP) is a sample of your own blood that is centrifuged to increase the concentration of platelets in the plasma. Because platelets contain bioproteins essential to the healing process, PRP infiltration promotes tissue repair and pain reduction.

What is the procedure?

The PRP is injected into the area to be treated under ultrasound or fluoroscopic guidance. A period of reasonable rest of one to three weeks is recommended after the infiltration, and depending on the type of PRP, a return to sports can be around the sixth week.

Since PRP comes from your own blood, the risk of rejection or allergic reaction is virtually non-existent. The effects may appear after a few weeks or months.

How long do the effects last?

The effects can be seen after a few weeks. The doctor can judge if a second infiltration is necessary.
