Meeting Information

2023 PAS Scientific Session & Annual Meeting
for Personalized Hip and Knee Replacement

This meeting supports the Society’s goal of bringing together the world’s most innovative surgeons and ingineers alongside the most forward-thinking companies in order to advance the state of personalized Hip and Knee arthroplasty to all patients, promoting the evolution of arthroplasty through education and discussion.

During this meeting, we will create clarity around the variations of the theme of personalized hip and knee surgery, while also considering the repercussions from surgical techniques, implant design and management of complex deformity in our space.

The world of arthroplasty is shifting from rudimentary systematic techniques to more sophisticated, personalized and physiological ones. If you share our vision and want to contribute to the paradigm shift, please join us at this grand mess of modern surgery!
