Summary
Robot-assisted navigation (RAN) in total knee arthroplasty (TKA) is more efficient and accurate than computer-assisted navigation (CAN). RAN reduces navigation time, improves alignment, and shortens hospital stays for TKA patients.
Area of Science:
- Orthopedic Surgery
- Robotics in Medicine
- Surgical Navigation Technologies
Background:
- Limited research compares robot-assisted navigation (RAN) with computer-assisted navigation (CAN) in primary total knee arthroplasty (TKA).
- Investigating the efficiency and accuracy of different navigation systems is crucial for optimizing TKA outcomes.
Purpose of the Study:
- To compare the efficiency and accuracy of Praxim robot-assisted navigation (RAN) versus Stryker computer-assisted navigation (CAN) in primary TKA.
- To evaluate navigation time, surgical accuracy, and patient recovery metrics between RAN and CAN systems.
Main Methods:
- Retrospective study involving 52 patients for RAN and 29 patients for CAN in primary TKA.
- Primary outcome: navigation time. Secondary outcomes: mechanical axis alignment, bone cut accuracy, tourniquet time, and hospitalization length.
Main Results:
- RAN demonstrated an average of 9.0 minutes shorter navigation time compared to CAN.
- RAN procedures showed 0.5° less average absolute intraoperative malalignment than CAN.
- Patients receiving RAN tended to have a 0.6-day shorter hospitalization length.
Conclusions:
- Robot-assisted navigation (RAN) in TKA is associated with reduced navigation time and improved accuracy compared to computer-assisted navigation (CAN).
- RAN utilization in TKA may lead to shorter hospital stays, enhancing overall patient recovery.
- These benefits of RAN over CAN in TKA are independent of patient age, BMI, and pre-operative alignment.
