I'll politely disagree with technique. A safer approach to avoid articular cartilage as well as the menisci and ACL/PCL is to use a superolateral entry and go retropatellar. Additionally, liquid contrast is unnecessary as air contrast outlines the suprapatellar recess in AP/Lat projections. I use 10cc air. But keep the videos coming. Excellent resource.

I would love to see a video of this air contrast that you mention; could be a great alternative to our Omnipaque/Isovue.

Thanks for the helpful comment. I use the superolateral parapatellar approach to aspirate large effusions (which I rarely see b/c they usually go to ortho first). But in residency, all of the Ortho, PM&R, and Anesthesia attendings I trained under did this medial or lateral parapatellar tendon approach. I can see your point about potential meniscus and ligament damage by the needle, but we don't use much force when resistance is encountered, and we don't inject under resistance.
