Navigation system helps surgeon to perform surgeries basis on 3D bone model therefore surgeon can avoid mal-positioning of implant intraoperatively.
Even for Knee replacement we need technology that gives us accurate, consistent & faster results . Computer Assisted Surgery (CAS) works in all patients, deformities with great deal of customization that Assured Success in TKR.
CAS results are proven and time tested. System can be compared with a GPS for automobile navigation. The camera replaces the satellite. The surgical instruments replace the car. Patient Anatomy compares with roadmap.
Advantages of CAS
- Increase in accuracy and precision of surgical interventions
- Less invasive operations (no intra-medullary instruments in case of Knee)
- Better planning and simulation
- Fewer Steps & Faster Procedures
- Step by step verification of surgical procedures
- Reduction of radiation exposure for both patient and surgeon
- Reproducible and comparable results
CAS TKR V/s Conventional TKR
|CAS TKR||Conventional TKR|
|CAS TKR increase in accuracy and precision of surgical interventions||CONVENTIONAL TKR is less accurate and lesser surgical interventions.|
|Less invasive operations (no intra-medullary instruments)||More invasive operations ( have to use intramedullary instruments )|
|Better planning and simulation||Lesser planning and simulation intra-operative.|
|Step by step verification of surgical procedures||No step by step verification of surgical procedures|
|Reduction of radiation exposure for both patient and surgeon||Radiation exposure is more for both patients and surgeon.|
|Reproducible and comparable results||No reproducible and comparable results.|
|Reduction of “tourniquet time”.||Increase “ tourniquet time ”|
|4’’ Scar with 15’’ penetration or 6’’ scar with no penetration.||Requires penetration of femoral medullary canal by 15’’ long rod increasing the chances of fat embolism.|
|Less blood loss||More blood loss|
|Faster recovery||Slower recovery.|
