Abstract

Context

ACL injury continues to be the largest single problem in orthopedic sports medicine. MRI has become the prime diagnostic tool of the various knee pathological and anatomical variability conditions.

Aim

To test the integrity of the new combined method for assessment of tibial plateau anatomic variables using conventional MRI.

Settings and design

Retrospective control study.

Methods

We evaluated the medial tibial plateau slope (MTPS), lateral tibial plateau slope (LTPS), and medial tibial plateau depth (MTPD) in ACL-injured group of patients (156) and non-ACL-injured control group (93) using MRI scan. Inclusion criteria for ACL-injured group—as surgically confirmed—were isolated ACL injury, while inclusion criteria for non-ACL-injured group were minor trauma, bruises, etc.

Statistical analysis used

Student’s t test and ICC were used. A p value of <0.05 was assigned as significant.

Results

Both male and female patients in the ACL-injured group showed increased LTPS in comparison to control group (p = 0.0197), whereas no significant difference in MTPS and MTPD was detected (p = 0.75 and 0.9, respectively). Steeper LTPS was detected in males of the patient group than in control group (p = 0.0001). Control group males had less steep MTPS (p = 0.002) and LTPS (p = 0.035) and deeper MTPD (p = 0.004) than control group females.

Conclusion

We conclude that the combined method conducted by Khan et al. (Int Orthop (SICOT) 2011 35(8):1251–1256) using conventional MRI for measurement of MTPS, LTPS, and MTPD as risk factors for ACL injury is solid and reproducible.
Level of evidence: III. Diagnostic study
