3-D printing creates knee model for evaluating patellar disorders and surgical approaches

A new, low-cost approach to building a knee model for studying knee pain and impaired mobility caused by abnormal movement of the patella uses a 3D printer to create a femur, tibia, patella, and the navigation system to guide knee reconstruction. The reconstructed knee model closely simulates the movement of the patella observed in cadaver knee models, as reported in the study published in 3-D Printing and Additive Manufacturing.
