-To identify meniscal variants and pitfalls to avoid unnecessary surgery.
-To review the ISAKOS classification consensus for meniscus tears to adequately plan surgery
-To provide a better understanding of the various surgical techniques to differentiate normal postsurgical meniscus appearance from retears and other complications, assessed with conventional MRI, direct CT-MR arthrography and arthroscopic correlation.
The menisci are semilunar fibrocartilaginous structures positioned between the femoral condyles and the tibial plateau which play an important role in the knee joint, including force transmission, shock absorption, lubrication, and stability. (Fig.2,3).
Meniscal tears are by far the most common knee injuries, and MRI is the non-invasive technique of choice to diagnose this pathology. (Fig.4,5,6A). Radiologists should keep pitfalls of meniscal tears in mind to make an accurate diagnosis. (Fig.7,8,9).
For treatment planning it is essential to describe the different meniscal tears using the...
Findings and procedure details
In this work, we review clinical indications, expected post-surgical findings on MRI and potential complications regarding three major surgical options related to meniscal tears: meniscectomy, meniscal repair, and meniscal replacement. (Fig.23). Some meniscal replacement options are still under development, so the information collected in this text will be limited.
One of the most important starting points for evaluating a postoperative meniscus is knowing what type of surgery has been performed and reviewing previous radiological tests. The clues to prior arthroscopic surgery on MR...
Knowledge of normal imaging findings and potential complications after meniscal surgery is essential to make an accurate diagnosis. The ISAKOS classification should be used to standardize communication between radiologists and surgeons.
