Background
The purpose of this study was to investigate the influence of posterior femoral
condylar depth on risk of sustaining anterior cruciate ligament (ACL) injury among
the Egyptian population.
Patients and methods
A total of 400 patients (200 ACL ruptured and 200 ACL intact) were included.
Morphometric parameters were measured on knee lateral radiographs, with
overlapping of the femoral condyles. Radiographic measurements included the
posterior femoral condyle offset (PCO) and ratio.
Results
The PCO and ratio showed significant differences between both groups. The
receiver-operating characteristic curve revealed that the PCO cutoff value of
more than 67.8 was associated with increased ACL injury with 76% sensitivity
and 74% specificity.
Conclusions
The data from our study demonstrated that an increase in posterior femoral condyle
ratio was associated with an increased prevalence of ACL injuries in Egyptian
population. However, further research is needed to determine the distal femur
morphology in the Egyptian population and its effect on the risk of primary and
secondary ACL injury.
