[Comparison of total knee arthroplasty with computer navigation systems and conventional techniques]
Summary
Computer navigation in total knee arthroplasty (TKA) shows similar mechanical alignment to conventional TKA but increases operation time. This method may also elevate risks of infection and fractures during the procedure.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Total knee arthroplasty (TKA) is a common procedure for knee osteoarthritis.
- Computer navigation systems aim to improve surgical accuracy and outcomes.
Purpose of the Study:
- To compare the clinical outcomes and safety of computer-navigated TKA versus conventional TKA.
Main Methods:
- Retrospective analysis of 45 primary unilateral TKAs (22 navigated, 23 conventional).
- Comparison of operation time, blood loss, complications, and functional outcomes (HSS score, ROM).
Main Results:
- Computer navigation did not significantly alter patellar retinacular release rates, blood loss, or final HSS scores and ROM.
- Navigated TKA showed significantly longer operation times and reduced drainage volume.
- Higher incidence of fracture and infection was observed in the navigated group.
Conclusions:
- Computer navigation in TKA achieves comparable mechanical alignment to conventional methods.
- The navigated approach prolongs surgery and may increase complication risks, including infection and fracture.
