Gphantom Knee is an anatomical simulator of the anterior region of the knee intended for the training of ultrasound-guided procedures. Made of Gphantom material, which offers realistic tactile sensation and precise anatomy, the model simulates the bony structures (patella, tibia and femur), synovial bag and tendons of the quadriceps and patellar. Gphantom Knee is indicated for practice, training and learning of ultrasound-guided procedures such as periarticular anesthesia, joint infiltrations, synovial fluid aspiration, biopsies, and others.
