Dr. Charles Mok explains the PRF knee injection procedure. The needle goes into the joint with local numbing, and you might feel tightness for a few days. Most people improve within a month, peak at two to six months, and some studies show cartilage growth with repeated treatments.

After your skin is numbed up, you really don't feel the needle in. There's a little discomfort with it, but it's almost none. The injection gets put into the knee joint and needles pulled out and you're done. That's it. Now, there might be some tightness feeling in your knee. It might be a little inflamed afterwards, but it's typically not much of anything. And typically you feel better pretty quickly within a month. And it peaks typically between month two and month six of improvement. There are have been studies showing there's some growth of cartilage. Again, the joint space is getting better, particularly doing repeated treatments. It's not necessarily one and done like a knee replacement where you've actually cut the joint out and put in a new metal joint that's going to last 10 or 15 years or 15, 20 years, or like a ceramic joint. There's going to be continued wear and tear. So this might be something you plan to do periodically. And we're thinking that most common pattern seems to be doing it two to three times in the first year and then about once a year after that.
