MRI Classification of Posterior Medial Meniscal Root Injuries: (AJR 2014; 203:1286–1292)

• Choi et al. introduced an MRI-based classification for posterior medial meniscal root lesions. 
• This classification encompasses a range of MRI findings related to meniscus posterior root attachment issues, including degeneration, partial tears, and complete tears.

 

Arthroscopic Classification of Meniscal Root Tears: (Am J Sports Med 2015; 43:363–369)

• In 2015, LaPrade et al. outlined a classification system for meniscal tears based on their morphology during arthroscopic surgery. 
• This classification comprises five distinct tear types and applies to tears in both the medial and lateral menisci occurring within 9 mm of the root attachment, as well as avulsion fractures of the meniscal root attachment.

 

Arthroscopic Classification Type 1: 

• This type represents a partial tear of the posterior root of the medial meniscus, characterized by fluid signal intensity at the root insertion point. 
• Additionally, subchondral and/or subenthesial linear bone marrow signal intensity is a secondary sign of a meniscal tear.
