Is the femoral lateral condyle’s bone morphology the trochlea of the ACL?

Is the femoral lateral condyle’s bone morphology the trochlea of the ACL?

Abstract


Purpose

The purpose of this study was to investigate the association of different osteoarticular femoral and tibial morphology and morphometric parameters with the risk of anterior cruciate ligament (ACL) rupture.


Methods

Thirty-six patients (29 male and 7 female) with an ACL rupture (

Results

It was found statistically significant smaller heights of femur’s lateral condyle, AP distances of the tibial plateaus and smaller XY and WX distances, as well as, higher XY/AB and B/AB ratios (p < 0.05). In turn, women had smaller AP distances of the femur’s lateral condyle, AP distances of the femur’s diaphysis, AP distances of the tibial plateaus and heights of femur’s lateral condyle, as well as, higher values of XY/AB (Porto ratio) and B/AB ratios (p < 0.05).


Conclusions

Several femoral and tibial bone morphological parameters were identified as potential risk factors for sustaining an ACL injury. These parameters are clinically relevant to identify individuals with higher risk of ACL injury, decide between conservative or surgical treatment and identify individuals who may benefit from preventive neuromuscular programs.
