Intraoperative Planning Platform for Personalized Joint Arthroplasty
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing total joint replacement surgeries face significant intra-operative technical errors and challenges in personalizing surgical plans, leading to unsatisfactory clinical outcomes due to improper cut parameters and soft-tissue management.
Innovation Solution
A computer-based platform that receives surgeon-specific and patient-specific data to generate a personalized surgical plan, incorporating bone registration, movement-related data, and implant profiles, using a surgical plan model to achieve desired functional performance, and outputs this plan on a graphical user interface for implantation guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical planning is used without personalization, then the surgical procedure can be performed with standard protocols, but intra-operative technical errors increase and clinical outcomes become unsatisfactory
Solution Approach 1:
The system changes surgical parameters from standard fixed values to personalized dynamic values by calculating patient-specific cut parameters based on bone registration data, functional profiles, and movement-related data. This allows the surgical plan to adapt to individual patient anatomy and requirements, improving both precision and reliability.
Solution Approach 2:
The system performs preliminary surgical planning and parameter calculation before the actual surgery. By pre-calculating personalized cut parameters and creating a virtual surgical plan based on pre-operative data, the system prepares all necessary guidance information in advance, reducing intra-operative errors and improving outcomes.
2Reliability
If surgical plans are not personalized to individual patients, then the planning process remains simple, but soft-tissue management and functional performance are compromised
Solution Approach 1:
The computer-based system acts as an intermediary between pre-operative data and intra-operative execution. It processes bone registration data, functional profiles, and movement-related data to generate personalized surgical plans, serving as a mediator that translates complex patient-specific requirements into actionable surgical guidance without overwhelming the surgeon.
Solution Approach 2:
The system incorporates feedback loops where movement-related data from intra-operative measurements is fed back into the surgical plan model. This allows continuous refinement of the surgical plan based on actual joint behavior during distraction, ensuring functional performance requirements are met while managing complexity through automated adjustments.
3Ease of operation
If standard surgical protocols are used without surgeon-specific guidance, then the workflow remains straightforward, but surgeon-specific techniques and preferences are not optimized
Solution Approach 1:
The surgical planning system transitions from static standard protocols to dynamic personalized plans that adapt to surgeon-specific preferences and intra-operative conditions. The system maintains ease of operation by presenting guidance information in an intuitive interface while enabling optimization of surgeon-specific techniques through customizable parameters and real-time adjustments.

AI summary
A method includes receiving by a controller, a surgeon-specific surgery profile for an implantation of an implant into a joint, implant profiles, a patient-specific post-surgery desired functional profile of the joint after the implantation, and bone registration data for a first bone member and a second bone member of a patient are inputted into a surgical plan model to generate a surgical plan. The surgical plan model is designed to achieve the patient-specific post-surgery desired functional profile based at least in part on a plurality of dependencies between a plurality of surgical parameters, the implant profiles, at least one functional parameter representative of the expected functional performance of the joint, and movement-related data of the joint. The surgical plan is outputted on a graphical user interface (GUI) on a surgery assistant device to facilitate the implantation.
