Knee Arthrocentesis and Intraarticular Injection

Dr. Jess Mason reviews how to do either a knee arthrocentesis or intraarticular joint injection, with procedure demonstrated by Physician Assistant Felicia Trasca. The approach is the same but for an arthrocentesis (aspiration) fluid is removed and for a joint injection pain medication and/or steroid is injected into the knee.

Not sure why you would not use Ultrasound for this. There is no guess work and in knees with small joint effusions it's a no brainer.

I would not use bupivicaine IA (ever). It's toxic to chondrocytes. Low concentration preservative free lidocaine (0,2%) and ropivacacaine (if you have it) are better options. (I inject hundreds of knees a year in an interventional pain clinic, hence the interest.) Thanks for the great videos!

Thanks for bringing this up. A quick search reveals many articles on this topic and I'm interested in discussing it further.
