Comparison of knee arthrocentesis first‐attempt success between Ultrasound‐Guided, Ultrasound‐Localised and Landmark‐Guided techniques in the novice: A crossover study with random order of events

In simulated knee arthrocentesis, ultrasound-guided techniques increased first-attempt success over landmark-guided techniques among medical students. This increase was most evident for arthrocentesis of smaller volume effusions.
