3D Surgical Planning for Personalised Joint Arthroplasty

The symposium was held at the Royal Society of Medicine in London on 28 March 2023 and brought together engineers, implant manufacturers, software developers, surgeons and regulatory bodies, to better understand how to optimise joint arthroplasty.  The focus was on the latest advancements in medical imaging, image analysis for surgical planning and evaluation of the outcomes of joint arthroplasty.  

The presentations in the 4 sessions exposed the need for orthopaedic surgeons to embrace the advances and incorporate the new technologies in their practice.  

3D surgical planning of hip and knee arthroplasty

Focus on the use of surgical planning for positioning tools, systems available, pros and cons for their use, and the clinical need for hip and knee personalized arthroplasty.

Michael Hirschmann from Basel presented on Personalised Alignment and Phenotypes in Knee Arthroplasty and underpinned his strategy on this subject.

3D surgical planning-enabled technologies and implant design

Emphasis on implant positioning technology, CT imaging segmentation in the presence of metal and implant design. In this session the speakers delivered consummate presentations based on their in-depth knowledge of their subject.

A panel discussion was held with industry (implant manufacturers and software experts) in the hot seats which generated a lively debate and at the same time emphasised the need for collaboration by all parties to obtain the maximum benefit from the technologies.

Post-operative implant position assessment and monitoring

Presentations on post-operative clinical assessment, radiographic and CT-based methods for implant migration analysis.

The session was led by Anna Di Laura, one of the co-organisers of CT Image Analysis for

Implant Monitoring. Demien Broekhuis from Leiden detailed his research on How to Perform RSA on Large Custom Hip Implants.

The future of 3D planning of joint arthroplasty

Talks on in-silico trials, planning and augmented reality, CT protocols and the need for harmonisation, and statistical shape modelling of the joints.

This session was anchored by Rebecca Bryan from Synopsys, who provided an insight into  the future with In Silico Trials - The Future for Implant Design, Testing and Certification.

The symposium achieved the goal of demonstrating the vital need to engage advanced technologies in all aspects of complex surgery, to improve patient care and outcomes in joint arthroplasty.
