Pearls and Pitfalls

Pearls	Pitfalls
Patient positioning must allow for free mobilization of the limb	If there's no crevice sign, it doesn't mean that there's no meniscal tear. Surgeons should still assess meniscus status meticulously.
The crevice sign is generally seen at roughly 90° of knee flexion, so it's important to seek for it at this flexion.	This sign does not occur on the lateral compartment.
In case of a crevice sign, it is paramount to assess properly the stability of the medial meniscus with a probe.	Be careful when you palpate the crevice sign not to damage the cartilage.
