Limitations and Future!
And by definition ‘the future’ is Unlimited & Ours to create!!
3D Printing Video
3D printing Avenues
Anatomical Models & Simulation tools
Patient Specific Jigs/ Instruments
3D printed Implants and Instruments
Bio Printing & Tissue Engineering
Models: where we started!
And today..
And yet..
Imaging dependant: Trash In -> Trash Out
Processing software are expensive time consuming
Surgeon dependant
Time Consuming
SEGMENTATION
Hopefully…
Better Images
Better Processing Algorithms
Artificial Intelligence to reduce Surgeon dependency
Quicker Turn around time
Cost: Well it is already rock bottom now!
Patient Specific Jigs/Instruments
Uses data from CT/ MRI/ X-rays
Planning is carried out in the preoperative stage
Surgeons and Engineers formulate a plan
Jigs are 3D printed and Shipped
Where we started…
Where we are now?
Current Limitations
No intraoperative measure to test the accuracy
Accuracy depends on the images/ Operators
Issues with the materials used for making these Jigs
Deals with all the deformities as static
The Future
Intraoperative integertaion with realtime navigation systems
Expansion to different areas beyond TKR/ Osteotomies and Resurfacing
Tactile feedback incorporation into the instrumentation systems
3D printed Implants
Era of ‘personalised medicine’
Newer materials are found suitable for implantation
Driven by better understanding of the human anatomy, physiology and biomechanics
Metal printing cost has dramatically fallen in last 2 years.
Exciting times!
Acetabular defects
Patient Specific Knees
Limitations
Still grappling with accuracy to match mass production
Material issues
Turn around time
Cost issues
Operator dependant
The Future
Newer Biocompatible materials: HA TCP printing/ Biopolymers
Faster turn around
Manufacture anywhere even in the OT
Get exactly what you and your patient require/ wish
Today - Limitations??
The Future is ‘Unlimited’
Bio printing - The Big Question?
Can we recreate what God created?
Yes we can - atleast try
Bioprinters
In vitro..
Regenerating Cartilage , Bones & Scaffolds
Use natural polymers: Collagen/HA/Silk Proteins/Alginate
Coupled with hydrogels - PGA/ PCL/Methacrylate
Cross linked chemically, thermally or using UV
Sprayed with hMSCs
We look forward to..
Going beyond the ‘hype’ phase to real action phase
Long term survivorship data
TKR becoming obsolete in my life time!
