Three-dimensional (3D) reconstruction and printing is transforming orthopaedic surgery, driven by advancements in CT and MRI technologies. These innovations facilitate preoperative planning, the development of patient-specific instrumentation (PSI), and custom implants, ultimately improving surgical outcomes. The rise of 3D-printed implants allows for precise anatomical modelling, enabling surgeons to rehearse complex procedures and tailor approaches to individual patient anatomies. This can lead to reduced operative times, decreased bleeding, and lower risks of implant malposition. Furthermore, 3D printing addresses the limitations of “one-size-fits-all” implants by offering bespoke solutions for complex joint replacements and revision surgeries. The evolution of 3D Printing began in the 1980s, with significant technological advancements leading to diverse applications across industries, including healthcare. Setting up 3D printing services in orthopaedics requires careful planning, regulatory compliance, skilled personnel, and continuous evaluation. Despite its potential, challenges such as the steep learning curve associated with 3D printing workflows and integrating PSI into routine practice must be addressed. As the technology matures, costs are expected to decrease, making it more accessible, particularly for low-volume surgeons. Furthermore, bioprinting may revolutionize orthopaedic treatment by offering cartilage and bone repair alternatives, paving the way for new therapies that enhance recovery and outcomes. This chapter explores the current landscape, challenges, and future directions of 3D Printing in orthopaedics, highlighting its transformative potential in patient care.
