Enhatch Earns FDA Nod for AI-Powered TKA Patient-Specific Instrumentation

Enhatch has gained U.S. Food and Drug Administration (FDA) 510(k) clearance for a patient-specific instrumentation system for total knee arthroplasty (TKA).
 
The system features artificial intelligence (AI) algorithms that convert patient X-rays or CT images into detailed, 3D anatomic models for use in treatment plans. This creates personalized surgical guides more efficiently, according to the company.
 
Enhatch said using X-ray-based preoperative planning can offer reduced exposure to radiation compared to traditional full-knee CT scans. X-rays are more accessible and widely reimbursed in the U.S., boosting operational efficiency and cost-effectiveness.
 
Enhatch senior project R&D manager Scott Mozelski said harnessing AI-drive technologies can optimize surgical workflows for patient-specific surgeries.
 
“Surgeons can effortlessly submit X-ray or CT images, along with treatment details and preferences,” he told the press. “Our advanced AI algorithms then go to work to generate precise anatomic models, information for preoperative plans, and surgical guide designs. Planners assess the generated outputs and actively collaborate with surgeons to ensure thorough review and approval of the preoperative plans.
 
The patient-specific instrumentation is manufactured, packaged, and shipped by Enhatch’s manufacturing partner 3D Systems to provide the instrument kits at the point of care. The duo began this partnership in June 2022.
 
“The recent FDA clearance represents a major company milestone in advancing surgical precision and elevating the standard of patient care. Our Intelligent Surgery Knee software plays a pivotal role in streamlining preoperative planning and crafting patient-specific guides with enhanced efficiency. Leveraging cutting-edge AI technology for accurate modeling of individual anatomies and planning treatments, we are setting new benchmarks within the industry,” commented Enhatch president and chief technology officer Michael Phipps.
