View abstract on PubMed
Summary
This summary is machine-generated.Artificial intelligence (AI) and human control in total hip arthroplasty navigation show similar accuracy for acetabular component positioning and leg length discrepancy. This study found no significant difference between AI-assisted and manual navigation systems in achieving optimal surgical outcomes.
Area Of Science
- Orthopedic Surgery
- Medical Technology
- Artificial Intelligence
Background
- Accurate implant positioning is crucial for successful total hip arthroplasty (THA).
- Intraoperative fluoroscopic-assisted computer navigation can enhance THA accuracy.
- The comparative accuracy of AI-driven versus human-controlled navigation for acetabular component position and leg length discrepancy (LLD) remains unstudied.
Purpose Of The Study
- To compare the accuracy of AI-controlled navigation software with human-controlled software in assessing acetabular component position and LLD during THA.
Main Methods
- A retrospective analysis of 420 primary THAs using fluoroscopic-assisted computer navigation.
- Two cohorts were compared: 211 THAs with manual (human technician) navigation and 209 THAs with AI-automated navigation.
- Acetabular component inclination, anteversion, and LLD were recorded intraoperatively and compared with postoperative radiographs.
Main Results
- Cup placement within the Lewinnek "safe zone" was high in both groups (94% manual vs. 95% AI, P = 1.0).
- Accuracy for LLD within ±2 mm was similar (69% manual vs. 66% AI, P = 0.47).
- High accuracy for LLD within ±5 mm was also observed in both groups (99% manual vs. 98% AI, P = 0.45).
Conclusions
- AI-controlled and human-controlled navigation platforms demonstrate comparable accuracy in achieving optimal acetabular component positioning and LLD during THA.
- The findings suggest AI can be a reliable tool in navigation-assisted THA without compromising accuracy.
