Patient-Specific Guides for Knee Reconstruction (OJSM)
Our OJSM-published study validating 3D-printed patient-specific instrumentation for knee reconstruction — clinical accuracy and workflow.
Background
Patient-specific instrumentation (PSI) represents a paradigm shift in orthopaedic surgery — from generic, one-size-fits-all approaches to precision-engineered solutions tailored to individual patient anatomy.
Our research team at Salnus developed and validated a workflow for designing and manufacturing 3D-printed surgical guides for knee reconstruction procedures. This study, published in The Orthopaedic Journal of Sports Medicine (OJSM), represents the first clinical validation of our PSI technology.
Key Findings
The study demonstrated:
- Improved intraoperative precision compared to conventional freehand techniques
- Reduced surgical time through pre-planned guide placement
- Consistent alignment accuracy across different surgeon experience levels
- No adverse events related to PSI usage during the study period
Clinical Workflow
Our PSI workflow consists of four stages:
- DICOM Acquisition — Standard CT or MRI imaging of the patient's knee
- 3D Reconstruction — Automated bone segmentation and surface mesh generation
- Guide Design — Patient-specific cutting guides designed to match exact anatomy
- Manufacturing — Medical-grade 3D printing with biocompatible materials
Implications
This publication establishes the foundation for our broader platform vision: integrating AI-powered analysis with patient-specific surgical planning. The same 3D reconstruction pipeline that powers our PSI guides now feeds into our automated measurement and OA grading modules.
"The transition from academic research to clinical application is not just about technology — it's about building systems that surgeons can trust with their patients."
