What did I do?

The overall aim of my thesis was to systematically evaluate medial meniscal ‘ramp’ lesions and how they affect anterior cruciate ligament reconstruction (ACLR).

Why did I do it?

There has been a recent surge in publications in the past decade regarding meniscal ramp lesions. Ramp lesions by definition are associated with ACL tears and have a high incidence (40%) in various ACL tear populations.1 A ramp lesion involves tearing of the posteromedial meniscus at the meniscocapsular junction and is of specific interest due to its reported ‘blind spot’ when viewing arthroscopically. Its name is derived from the arthroscopic appearance of a downwards slope or ramp and authors have associated an arbitrarily tear length of 2.5 cm to describe an unstable ramp lesion.2 Because of this slope or ramp area, the posteromedial capsule of the knee creates a fold which allows for a potential hidden space, thus resulting in misdiagnosis and failure …
