The purpose of this study is twofold: 1) to define the anatomy and structure of the anterior horn lateral meniscus (AHLM) and posterior horn medial meniscus (PHMM) root ligament attachments in human cadaveric knees on an 11.7T MR scanner with histologic correlation, and 2) to identify commonly encountered patterns of failure and associated lesions in these root ligament attachments based upon review of 500 clinical MRI knee studies.  

The anatomy and structure of the AHLM and PHMM root ligaments will be profiled in cadaveric specimens using an 11.7T MR scanner with 112 x 112 x 120 μm resolution (TR20 ms; TE 7 ms), with histologic correlation. The transition of meniscal tissue/ root ligament/ enthesis will be profiled, as well as the relationship of the root ligaments to surrounding structures. Commonly encountered patterns of AHLM and PHMM root ligament failure documented on clinical MR studies will be demonstrated. Patterns of failure will be related to AHLM and PHMM anatomy and structure, and classification systems will be proposed.  

AHLM and PHMM Root ligament anatomic and structural characterization will facilitate a better understanding of patterns of failure in these tissues and allow development of clinical classification systems that better characterize disease.
