Purpose:To evaluate the postoperative magnetic resonance image (MRI) findings of anterior cruciate ligament (ACL) reconstructed with a tension load technique using auto-Achilles tendon, and to compare the results with knees with a native ACL.
Materials and Method :We evaluated 21 postoperative MRI scan of 21 patients (group A) who had undergone ACL reconstruction between January 1995 and November 1996. The control group (group B) consisted of 50 patients whose meniscus tear had been operated by arthroscopy and whose ACL was intact. We measured the orientation of the graft in the sagittal and coronal planes and compared it with that of the native ACL.
Results:The mean sagittal angle of the ACL angle in group A (55.7±5.6˚, range 47.2~68.8˚) was statistically lesser than group B (58.7±3.8˚, range 50.4~67.5˚) (p=0.036). But there was no statistically significant difference between the two groups with regard to the mean ACL-Blumensaat line angle (group A: 8.1˚±4.9˚, range 1.7˚~22.0˚, group B: 8.6˚±3.6˚, range 2.6˚-18.1˚) and the mean coronal angle of the ACL (group A: 64.9˚±9.1˚, range 46.9˚~76.4˚, group B: 65.9˚±4.4˚, range 57.7˚~75.2˚)(p=0.88, p= 0.62). In the sagittal plane, the mean center of tibial insertion of the ACL graft in group A (31.9±7.1%, range 22.4-47.9%) was positioned more anteriorly than group B (37.0±4.9%, range 18.5~44.7%)(p=0.005). But in the coronal plane, there was no statistically significant difference between the two groups(group A: 46.3± 2.8%, range 42.1~52.5%, group B: 45.7± 2.8%, range 41.0~49.1%)(p=0.392).
Conclusions:We performed an ACL reconstruction with the tension load technique using auto-Achilles tendon and we found that the graft orientation in MRI was as good as that of the native ACL.
