- Surgical Instrumentation
- Biomedical Engineering
Background:
- Total knee arthroplasty (TKA) has seen significant instrumentation advancements.
- Navigation technology has become a key development in TKA over the past decade.
Purpose of the Study:
- To review the evolution and application of navigation in TKA.
- To discuss the established benefits and remaining questions regarding navigation's impact on TKA outcomes.
Main Methods:
- Review of literature on surgical navigation in TKA.
- Analysis of incorporated surgical steps and parameters controlled by navigation systems.
Main Results:
- Navigation offers precision control for alignment, component rotation, and ligament balancing.
- Proven efficacy in improving lower-limb axis alignment during TKA procedures.
Conclusions:
- Navigation is a valuable precision tool in TKA, enhancing surgical accuracy.
- The clinical significance of navigation-assisted alignment and its effect on long-term TKA survival remain areas for further research.
