Health Imaging reports:
An analysis of MR scans of male and female athletes with non-contact
anterior cruciate ligament (ACL) injuries and similar athletes without a
history of ligament injury found that injured athletes had shorter,
more highly convex articulating surfaces than non-injured athletes,
according to a study published Feb. 1 in The Journal of Bone and Joint Surgery.
Women
have an ACL injury rate two to five times greater than men. Cumulative
annual costs of ACL ruptures in the U.S. are estimated at $1 billion,
and a great deal of research has attempted to uncover the cause of
female athletes’ predisposition to ACL injury.
Christopher J.
Wahl, MD, of the department of orthopaedics and sports medicine at
University of Washington in Seattle, and colleagues hypothesized that
articular surfaces of the lateral aspect of the tibial plateau and/or
the distal aspect of the femur would be more highly convex in patients
with ACL injuries. They also suspected that the convex geometry would be
more prevalent among female athletes.
Three observers, blinded
to patient information, analyzed knee MRI scans of 112 athletes with a
non-contact ACL injury and 61 activity-matched athletes without an ACL
injury. They measured femoral anteroposterior length (FAP), tibial
plateau anteroposterior length (TPAP), tibial plateau radius of
curvature (TPr) and fibonacci femoral radius of curvature (Fr).
