Knee Injections Q & A

What are knee injections?

Knee injections offer pain relief and improve mobility if you have problems with your knees. The most likely reason for needing knee injections is arthritis in your joints. Of the 100 kinds of arthritis, the ones that most commonly affect the knees are:  

  • Osteoarthritis
  • Post-traumatic arthritis
  • Rheumatoid arthritis
  • Psoriatic arthritis 
  • Septic arthritis
  • Gout

Knee injections are also valuable in treating conditions like bursitis and tendinitis.

What’s in a knee injection?

Knees First uses several types of knee injections, including:

Stem cells 

Your body uses stem cells to replace damaged cells of any kind in your body. If you injure yourself, stem cells arrive in your blood to help with healing. 

However, as you get older, your stores of stem cells decline, so fewer reach the damaged tissues. Knees First injects concentrated doses of stem cells into your knees to boost regeneration.

Platelet-rich plasma (PRP)

PRP knee injections are another natural method of boosting healing. The shots contain platelets from your blood that are full of growth factors, which enhance tissue repair.

Hyaluronic acid 

Hyaluronic acid injections (also called viscosupplementation) contain a natural lubricant. Healthy knees have plenty of hyaluronic acid in the synovial fluid that bathes the joint. 

However, people with arthritis typically have low levels in their joints, so knee injections containing hyaluronic acid increase lubrication, which eases pain and stiffness.

Steroid injections might be helpful for some patients. However, because overuse of steroids can harm the joints and cause side effects, you can only have a limited number of injections.

What happens when I have my knee injection?

Before a knee injection, your Knees First provider cleans the site and uses a local anesthetic to numb the area. They use real-time ultrasound imaging to see the structures in your knee, which helps guide the needle to the right place inside your joint.

If fluid builds up in your knee, your provider connects an empty syringe to the needle, then extracts the excess fluid. This process is known as aspirating the knee. When it’s complete, your provider injects the stem cells, PRP, or hyaluronic acid into the joint.

The injection site may be a little sore afterward. This soreness soon wears off, and you can carry on with your regular activities in a day or so. The results should become apparent 2-7 days after your knee injections. They can last from a few days to several months.
