Additive Manufacturing in Total Joint Arthroplasty.

Additive manufacturing (AM) has demonstrated the potential to revolutionize manufacturing for various applications across the medical, aerospace, automobile, and energy sectors. It is a layer-by-layer manufacturing process in which the computer-aided design model is sliced into layers and each layer is deposited successively to realize the final product. This article provides a general overview of AM and discusses current state-of-the-art AM methodologies as they apply to total joint arthroplasty. Specifically, details on their applications and current challenges are summarized to provide orthopedic surgeons with a basic understanding of current and potential applications of AM in total joint arthroplasty.
