Abstract
Objectives.
The purpose of this paper is to identify the traumatic lesions of the
anterior cruciate ligament, as well as the associate osteo-meniscal-
ligamentous lesions.
Material and Methods.
We have made a
retrospective study on a plot of 1080 patients between January 2007 and
December 2008 with trauma injuries of the knee. The magnetic resonance
machine used is Siemens, Magnetom, Harmony 1T.
Results.
Of the 1080 patients from our study, 912 patients (84,4%) were
diagnosed through MRI with ACL injuries, 648 patients (71,1%) with
partial ACL rupture and 264 patients (28,9%) with ACL tear.
The
ACL injuries were associated with bony contusions (osteochondral
lesions and bone marrow edema) at: the tibia plateau (81,6%), the
lateral (57,9%) and the medial femoral condyle (52,6%); with medial
collateral ligament injury (50%) and lateral collateral ligament
injury (36,8%), as well as lateral (47,4%) and medial (42,1%)
meniscus injury. The PCL was injured in a very small percentage of
2,45%, due to its strength and structure.
Conclusions.
After knee trauma ACL injuries appear frequently. Most of the ACL
injuries are partial tears; the torn ACLs aren’t as frequent.
The
ACL injuries are often associated with bony contusions, especially in
the lateral femoral condyle and in the postero-lateral tibia plateau,
with MCL injuries and torn lateral meniscus.
