Arthrocentesis Training Package

Anatomically correct and perfect for practicing diagnosing and managing the presence of an effusion, our training package includes the Arthrocentesis Trainer with an additional replaceable tissue. The trainer represents an extended left leg and has ultrasound compatible features, including: the patella, patella ligament, tibia, fibula, femur, synovial sac, and synovial fluid. Synovial fluid can be aspirated from a joint cavity using either the medial or lateral approach and insertion sites include suprapatellar and parapatellar.
