To systematically review the relationship between version and torsional abnormalities of the acetabulum, femur, and tibia in patients with primary femoroacetabular impingement (FAI) and assess its clinical significance.
Key Findings:
68% of hips with FAI or dysplasia showed abnormal femoral and/or acetabular version, indicating a high prevalence of these abnormalities.
42% of patients with FAI and dysplasia exhibited abnormal tibial torsion, suggesting a need for comprehensive assessment.
A significant correlation exists between the combined index of acetabular and femoral version with hip rotation, which may influence treatment approaches.
Interpretation:
Version abnormalities are prevalent in patients with symptomatic FAI and may impact surgical outcomes, highlighting the need for careful assessment in clinical decision-making to optimize treatment strategies.
Limitations:
No systematic reviews previously characterizing version and torsional deformities in FAI, indicating a gap in the literature.
Potential biases in included studies as assessed by the MINORS criteria, which may affect the reliability of the findings.
Conclusion:
Understanding version and torsional abnormalities in FAI is crucial for optimizing treatment strategies and improving patient outcomes, warranting further research in this area.
