Summary
Imageless navigation for total hip arthroplasty (THA) shows similar implant positioning and dislocation rates compared to conventional THA. While it slightly improves leg length discrepancy, it increases surgical duration.
Area of Science:
- Orthopedic Surgery
- Surgical Navigation Technologies
- Biomechanical Engineering
Background:
- Growing interest in imageless navigation for primary total hip arthroplasty (THA).
- Debate exists regarding its superiority over conventional THA.
- This meta-analysis evaluates key outcomes of imageless navigation versus conventional THA.
Approach:
- PRISMA 2020 guidelines followed for study conduct.
- Comprehensive database search (PubMed, Web of Science, Google Scholar, Embase) without time constraints.
- Inclusion of clinical trials comparing imageless navigation with conventional primary THA.
Key Points:
- Twenty-one studies (2706 procedures) were analyzed.
- Imageless navigation showed a slight reduction in leg length discrepancy (P=0.02).
- Navigated procedures had a longer surgical duration (P<0.0001), with similar cup positioning, Harris Hip Score, and dislocation rates.
Conclusions:
- Imageless navigation is a viable option for total hip arthroplasty.
- Further research may explore optimizing surgical time.
- Clinical outcomes suggest comparable efficacy to conventional THA.
