Our SynAtomy Arthrocentesis Knee trainer is a high-fidelity synthetic knee ideal for teaching students how to perform or assist in arthrocentesis. Continuous practice on this lifelike simulator will help students build their skills and confidence in a safe and biohazard-free environment.


This right knee model utilizes lifelike capabilities such as aspiration resistance when a needle tip is superficial to the joint capsule. Ultrasound compatible anatomic features include the patella, tibia, fibula, femur, synovial sac and synovial fluid. Simulated synovial fluid may be removed medially or laterally.

Extraordinary Features: SynTissue synthetic human tissues are made from salt, water and fiber—which feature the world’s most realistic tactility. SynTissue synthetic human tissues match the acoustical characteristic of real human tissue.
