About the Collection

With the aging population and increasing demand for improved quality of life, hip and knee arthroplasty has become crucial in modern healthcare. While effective, traditional methods often lack precision and optimal outcomes. Recent advancements in technology, particularly robotic assistance, have revolutionized these procedures. Additionally, integrating navigation systems, 3D-printed implants, and other innovations have enhanced surgical precision and patient outcomes.

This Special Collection aims to explore the latest advancements in hip and knee arthroplasty technologies. It focuses on robotic assistance while also examining other cutting-edge technologies, analyzing clinical applications, and identifying future research directions. The goal is to foster innovation and broader application of these technologies in joint replacement surgeries.
Scope and specific themes include:

•   Innovative Preoperative Planning Technologies: Utilizing advanced algorithms and AI to optimize surgical plans based on CT and MRI data, ensuring precise osteotomy and implant positioning.
•   Robotic and Navigation Systems: Exploring the synergy between robotic arms and navigation technologies to enhance surgical accuracy and stability.
•   3D-Printed Implants and Customization: Analyzing the impact of custom implants tailored to individual anatomy, improving fit and function.
•   Clinical Outcomes and Case Analysis: Evaluating the effectiveness of these technologies through clinical cases, focusing on metrics like surgical time, blood loss, complication rates, and recovery periods.
•   Strategies for Complex Cases: Discuss the application of advanced technologies in handling complex conditions, such as developmental dysplasia of the hip and severe knee deformities.
•   Cost-Effectiveness and Promotion Analysis: Examining the economic aspects of these technologies, and exploring strategies to enhance accessibility and affordability.
•   Future Technological Integration and Prospects: Looking at the integration of technologies such as virtual and augmented reality, and their potential impact on the future of joint replacement surgeries.
