Objective:
To evaluate short-term clinical outcomes and radiographic implant alignment in hip resurfacing procedures performed with and without intraoperative navigation.
Methodology:
A retrospective cohort study of 76 hips (38 with navigation, 38 without), with a minimum 2-year follow-up, examining postoperative function, pain scores, and radiographic component placement accuracy.
Key Findings:
- Clinical outcomes (pain relief and function) were similar across both groups.
- Navigation significantly improved the accuracy of component alignment.
- Odds of placing implants within safe alignment zones increased 6.8× and 28.8× with navigation for two key radiographic parameters.
Conclusion:
While short-term outcomes are comparable, navigation improves component placement accuracy, which may reduce future revision risk due to malalignment.
What Does This Mean for Providers?
For surgeons performing hip resurfacing, especially in younger or more active patients, navigation can enhance precision in component positioning—an important factor in long-term implant survival and function. While immediate outcomes may be similar, improved alignment may lower complication rates such as edge loading, early wear, and implant loosening. Consider navigation technology particularly in patients with abnormal anatomy or high functional demand.
