**Arthrocentesis** Ultrasound is a useful adjunct in the evaluation of the patient
with a swollen, painful knee. Ultrasound can identify a suspected knee effusion 
as well as assist with Closed joint aspiration .

 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 Closed joint aspiration success, greater synovial
fluid yield, more complete joint decompression, and improved clinical outcomes.

### **Which ultrasound scanner is best for arthrocentesis?**

A linear transducer (7.5 – 10 MHz) [SIFULTRAS-](https://sifsof.com/product/wireless-linear-probe-portable-ultrasound-scanner-sifultras-5-31/)
[5.31](https://sifsof.com/product/wireless-linear-probe-portable-ultrasound-scanner-sifultras-5-31/)
for both the identification of the effusion and needle guidance for the arthrocentesis

  Point-of-care ultrasound can accurately determine the presence of a joint effusion
as well as guide synovial fluid aspiration

 A simplified in-plane technique can easily be incorporated into the evaluation 
of the patient with a suspected septic knee. Ultrasound is effective in the identification
of knee effusion as well as allow for real-time visualized technique for joint aspiration.

 The suprapatellar bursa, the largest communicating bursa of the knee joint, allows
for a location that is easily visualized with ultrasound and can be rapidly and 
safely accessed for joint arthrocentesis.

  In the emergency department setting, ultrasound-guided knee arthrocentesis helps
minimize attempts as well as improve procedural confidence in the hands of novice
providers. Additionally, the suprapatellar approach under ultrasound guidance avoids
any tendons or bony or ligamentous structures and facilitates simple and accurate
Closed joint aspiration for the provider.

 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 Closed joint aspiration success,
greater synovial fluid yield, more complete joint decompression, and improved clinical
outcomes.
