Summary
This study found that a high-grade Lachman’s exam and male sex were significantly associated with patients with an ACL tear with a concomitant medial meniscus ramp tear. These findings suggest that an ACL tear with concomitant medial meniscus ramp tear may be better diagnosed based upon the clinical evaluation rather than other secondary radiological findings.

Abstract
Background
Medial meniscus ramp tears are present in 22.9–40.8% of anterior cruciate
ligament tears. The diagnosis of ramp tears is difficult on MRI, with sensitivity reported around
48%, which has recently emphasized the importance of proper arthroscopic probing for ramp tears.
Methods
A prospective evaluation was performed on patients undergoing a single bundle ACL
reconstruction to assess patient demographics, posterior tibial slope, posterior cruciate ligament
angle, Lachman’s exam, and rotational instability to determine secondary findings associated with
medial meniscal ramp tears.
Results
A total of 96 patients underwent ACL reconstruction, of these,
63 patients had an isolated ACL tear, and 33 patients had an ACL tear with a concomitant medial
meniscus ramp tear. A high-grade Lachman’s exam and male sex were associated with medial
meniscus ramp tears. There were no differences in posterior tibial slope, posterior cruciate ligament angle, or rotational instability between groups.
Conclusions
This study found that a high-grade Lachman’s exam and male sex were significantly associated with patients with an ACL tear with a concomitant medial meniscus ramp tear. These findings suggest that an ACL tear with concomitant medial meniscus ramp tear may be better diagnosed based upon the clinical evaluation rather than
other secondary radiological findings.
