Purpose
To assess tibial translation and frequency of associated injuries in patients with partial or full thickness tear of anterior cruciate ligament (ACL) after acute trauma.
Methods and Materials
Retrospectively,
were evaluated 91 MRIs of patients with acute knee injury suspected for ACL tear.
MR was performed on 1.5T Simens Somatom Essenza and MR protocol was: T1 COR; T2FS COR,
PDFS SAG; PD SAG; PDFS TRA; T1 TRA and T2 PARACOR.
The mean age were 30 years (range 14 to 68 years). A full thickness ACL tear was present in 56 cases (61,5%) and partial ACL tear in 35 cases (38,5%)
Consecutive arthroscopy was done within one month.
On MRI tibial anterior translation was...
Results
The mean value of tibial translation in patients with complete tear was 6.75mm (range 0-12mm),
in comparison to translation in cases with partial tear which was 3.4mm (range 0-11mm),
with significant statistical difference between two groups (p<0.001,
α=0.05).
Joint effusion was more severe in patients with complete ACL tear grade 2 (22/56,
40%) or grade 3 (21/56,
37,5%) when compared to the group of partial ACL tear grade 2 (13/35,
37%) or grade 3 (6/35,
17%) (Fisher’s exact p-value 0.03001).
Articular chondral lesions were more...
Conclusion
Tibial anterior translation is present in cases with complete and partial ACL tear,
but is bigger in cases with complete tear.
Chondral lesions were more severe in patients with full ACL tear when compared to cases with partial ACL tear.
Meniscal abnormalities and bone marrow oedema are the same in both groups most probably due to same mechanism of injury,
only the force severity is different.
