The Blue Phantom MSK Ultrasound Knee Task Trainer includes all of the essential anatomy to accurately teach and practice ultrasound guided joint injections and aspirations. The Musculoskeletal anatomy of the knee consists of the Quadriceps Tendon, Distal Femur Bone, Proximal Tibia/Fibula, and Patella. The Patella Bursa, Femur Fat Pad, Quadriceps Fat Pad and Percutaneous Fat Tissue are also included to provide the user live feedback of where they are directing the needle. The Patellar Bursa and suprapatellar space can be adjusted with Blue Phantom refill fluid to simulate different pathology within the knee. The knee comes preset at a 15 degree flexion angle with the ability to flex the knee an additional 10 degrees to create different target angles.
