Summary
Computer-assisted surgery (CAS) enhances orthopaedic procedures by making them patient-specific and quantitative. Establishing clinically relevant specifications with known targets and tolerances is crucial for effectively utilizing CAS tools in navigated and robotic surgeries.
Area of Science:
- Orthopaedic Surgery
- Medical Technology
- Surgical Navigation
Background:
- Computer-assisted surgery (CAS) aims to personalize orthopaedic procedures, making them minimally invasive and data-driven.
- CAS integrates preoperative planning, intraoperative execution, and postoperative evaluation for precise surgical interventions.
- The shift towards quantitative data in CAS necessitates defined clinical specifications for decision-making.
Purpose of the Study:
- To provide an overview of computer-assisted surgery in orthopaedics.
- To highlight the importance of quantitative data and specifications in CAS.
- To discuss the application of CAS in knee replacement and ligament reconstruction.
Main Methods:
- Review of computer-assisted surgery principles and components.
- Examples of quantitative surgery in navigated total knee replacement and anterior cruciate ligament reconstruction.
- Discussion of robotic unicondylar knee replacement as a recent CAS application.
Main Results:
- CAS tools facilitate patient-specific, minimally invasive, and quantitative orthopaedic surgery.
- Quantitative data and surgeon intuition are increasingly integrated in CAS for clinical decisions.
- Defined technical specifications with targets and tolerances are essential for CAS effectiveness.
Conclusions:
- Computer-assisted surgery provides tools for quantitative surgical approaches.
- Further clinical and basic-science research is needed to define precise technical specifications for navigated procedures.
- Effective use of CAS requires reliable measurement of clinically relevant specifications by the technology.
