Publication trends and knowledge mapping in 3D printing in orthopaedics

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Medical Imaging

Background:

• Three-dimensional (3D) printing, also known as additive manufacturing, is revolutionizing medical applications.
• It enables the creation of patient-specific anatomical models from CT/MR images for enhanced surgical planning and customized implants.
• Emerging areas include 3D bioprinting and artificial cartilage scaffold development.

Purpose of the Study:

• To analyze publication trends of 3D printing applications in orthopaedics.
• To identify key research areas, publication types, and geographical distribution of 3D printing research in orthopaedics.

Main Methods:

• Comprehensive literature search conducted on PubMed, Web of Science, and SCOPUS databases using specific keywords.
• Data analysis focused on publication volume, research type (basic science vs. clinical), and geographical origin.
• Citation analysis and identification of top-cited articles were performed using SCOPUS and Web of Science.

Main Results:

• A notable increase in publications related to 3D printing in orthopaedics was observed.
• China, the United States, the United Kingdom, and India are leading countries in publications.
• A significant portion of engineering-focused publications were identified, with fewer in the medical field.

Conclusions:

• There is a clear surge in research interest and publications concerning 3D printing in orthopaedics.
• While the field is still developing with challenges in knowledge and cost, 3D printing shows significant future potential for orthopaedics and trauma.
• Continued research and development are expected to drive further innovation in patient-specific orthopedic solutions.
