Meniscal root tears: diagnosis and treatment.
Meniscal tears within the body of the meniscus or at the meniscocapsular junction represent a well-understood and manageable condition encountered in clinical practice. In comparison, however, meniscal root tears (MRTs) often go unnoticed and represent a unique injury pattern with unique biomechanical consequences. Though first described decades ago, improvements in magnetic resonance imaging and arthroscopy have only recently enhanced our diagnostic and treatment capabilities with regard to MRTs. This review contains an anatomic description of the roots including their significance in meniscal function as well as the consequences of their loss. In addition, how to properly identify MRTs and when it is appropriate to surgically repair them are described. Finally, we review the surgical techniques available in the existing literature and present an illustrative case.
