Porous Nitinol Knee Implants and 3D Printing

This assignment provides a detailed overview of porous nitinol, a high-strength, low-stiffness metal alloy that resembles bone. It discusses the use of porous nitinol in knee implants, its osseo integration properties, and the challenges of nickel leaching. The assignment also touches on the benefits of 3D printing in customizing these implants, including the ability to engineer porosity and promote osseo integration. A case study of a British opera singer who underwent total knee replacement surgery using 3D printed knee implants is presented, highlighting the potential of this technology.
