Although this approach is not covered in this article, it seems that ultrasound-guided arthrocentesis and injection of the knee are superior to arthrocentesis and injection guided by anatomic landmarks and palpation, resulting in significantly less procedural pain, improved arthrocentesis success, greater synovial fluid yield, more complete joint decompression, and improved clinical outcomes.
