Comment to: The Wave Sign Correlates with the Posterior Horn Medial Meniscus (PHMM) Tear in the Anterior Cruciate Ligament (ACL) Deficient Knee
Abstract
I am writing in regards to the retrospective “Wave Sign” study by Gan et al1. The authors propose that this sign correlates with the Posterior Horn Medial Meniscus (PHMM) Tear in the Anterior Cruciate Ligament (ACL) Deficient Knee. Despite a small sample size, they recommend the use of the sign as a valuable arthroscopic identification aid. In terms of the referencing, they make no reference to a strikingly similar study from 2022 by Murgier et al2,3 in which they describe an identical sign but named differently, as the crevice sign. The latter study confirmed the hypothesis that there would be a strong correlation between the presence of an unstable medial meniscal tear in patients with the crevice sign in ACL-deficient knees.
