Ultrasound-guided Arthrocentesis

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-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.

Orthopedic surgeons, sports medicine doctors, and rheumatologists commonly perform arthrocentesis
