Distance between tibial tubercle and trochlear groove correlates with lower limb axial alignment
Maximiliano Barahona Vasquez
University of Chile, Chile
Purpose:
To correlate the tibial tubercle to trochlear groove distance with axial limb alignment. The hypothesis is that
as internal torsion of the distal femur or external torsion of the proximal tibial increase, the tibial tubercle to trochlear
groove distance increases.
Methods:
We designed a cross-sectional study approved by our institutional ethics review board. We reviewed 32
computed tomography angiographies of asymptomatic patients. Lower limb torsion, femoral torsion, tibial torsion and
tibial tubercle to trochlear groove distance were measured. A regression analysis between the tibial tubercle to trochlear
groove distance and the articular torsion was performed.
Results:
Apositive correlation between the tibial tubercle to trochlear groove distance and the articular torsion was found.
Conclusions: As external torsion between proximal tibia and distal femur increased the tibial tubercle to trochlear groove
distance does so. For a correct interpretation of the tibial tubercle to trochlear groove distance, the axial alignment should
be included in the regular analysis of patellofemoral disease.
