Hypothesis
Higher femoral anteversion could be a risk factor for non-contact ACL injury.
Conclusion
Increased femoral anteversion is associated with a higher risk of ACL injury among male athletes.
Supporting Evidence
- The mean anteversion in patients with ACL tears was higher compared to ACL-intact patients.
- Correlation analysis revealed an excellent correlation between femoral anteversion measured by CT scan and Craig's test results.
- Cut-off values for femoral anteversion were calculated to find the best margin for a high probability of ACL tearing.
Takeaway
This study found that athletes with a certain leg angle called femoral anteversion are more likely to hurt their knees without any contact.
Methodology
A retrospective comparative study was conducted on 137 adult male athletes with high suspicion of ACL injury, measuring femoral anteversion using CT scans and physical examinations.
Potential Biases
Potential selection bias due to the retrospective design and exclusion of certain demographics.
Limitations
The study's retrospective nature may increase biases, and results may not be generalizable to female athletes.
Participant Demographics
137 active male athletes aged 18–35, primarily involved in volleyball, basketball, and soccer.
