Abstract
Introduction:Meniscus injury is now widely being diagnosed and managed. Meniscus acts as a shock absorber and transmits forces from femur to tibia. However, if the meniscus is torn, the hoop strength is lost. In hidden meniscus injuries, budding arthroscopy surgeons tend to miss the tear. AMR sign acts as a light-bearer for identifying the breach in the collagen architecture. Methods and Materials: 267 patients were included in the study. Informed written consent was taken from all the patients operated and included in the study. Following a fixed protocol of diagnostic arthroscopy, documentation of AMR sign and its relation with intactness of the medial meniscus was done. If medial meniscus tear was found, after repair, its relation with AMR sign was documented.

Summary
Meniscus acts as a shock absorber and transmits forces from femur to tibia. If the meniscus is torn, the hoop strength is lost. In hidden meniscus injuries, budding arthroscopy surgeons tend to miss the tear. Meniscus does not justplays an important role in the knee joint by force transmission. It maintains congruency of the joint, lubrication and provides. AMR sign acts as a light-bearer for identifying the breach in joint stability.[1,2,3] Meniscus is injured in almost all the the collagen architecture
