Summary
The first robot-assisted total knee arthroplasty (TKA) in Brazil was successfully performed. This innovative procedure for TKA revision surgery offers enhanced precision and reduced tissue trauma, marking a significant advancement.
Area of Science:
- Orthopedic Surgery
- Robotic Surgery
- Arthroplasty
Background:
- Robotic-assisted joint replacement offers improved precision and reduced trauma.
- Studies on robotic-assisted total knee arthroplasty (TKA) revisions are limited.
- Brazil introduced robotic-assisted hip and knee arthroplasty in 2021.
Purpose of the Study:
- To report the first robot-assisted TKA revision in Brazil.
- To highlight the pioneering use of robotic technology in complex knee revisions.
Main Methods:
- A 61-year-old female patient with a failed unicompartmental knee arthroplasty (UKA) underwent robot-assisted TKA.
- The Mako robotic system was used for anatomical marking, bone preparation, and component placement.
- Procedure involved removal of previous components and ligament balancing.
Main Results:
- The robot-assisted TKA revision was performed successfully.
- The surgery demonstrated precise bone cuts and component alignment.
- The patient experienced a favorable postoperative course.
Conclusions:
- Robot-assisted TKA is a viable option for revision surgery.
- This case represents a pioneering step in robotic knee arthroplasty in Brazil.
- Further research is needed to standardize protocols for robotic TKA revisions.
