The main objective of this review was to present a synthesis of the current literature in order to provide a useful tool to clinician in radiologic analysis of the meniscus. All anatomical descriptions were clearly illustrated by MRI, arthroscopy, and/or drawings. The value of standard radiography is extremely limited for the assessment of meniscal injuries but may be indicated to obtain a differential diagnosis such as osteoarthritis. Ultrasound is rarely used as a diagnostic tool for meniscal pathologies and its accuracy is operator-dependent. CT arthrography with multiplanar reconstructions can detect meniscus tears that are not visible on MRI. This technique is also useful in case of MRI contraindications, in postoperative assessment of meniscal sutures and the condition of cartilage covering the articular surfaces. MRI is the most accurate and less invasive method for diagnosing meniscal lesions. MRI allows confirming and characterizing the meniscal lesion, the type, the extension, its association with a cyst, the meniscal extrusion, and assessing cartilage and subchondral bone. New 3D-MRI in three dimensions with isotropic resolution allows the creation of multiplanar reformatted images to obtain from an acquisition in one sectional plane reconstructions in other spatial planes. 3D MRI should further improve the diagnosis of meniscal tears.

The association of an anterior cruciate ligament (ACL) tear and a posterior cruciate ligament (PCL) injury is rare in athletes, and to our knowledge it has never been described in a professional rugby player. We report the case of a 27-year-old international professional rugby player who presented with an ACL tear associated with chronic posterior laxity on a former PCL tear. The procedure associated arthroscopic ACL and PCL reconstruction in a one-stage operation with two autografts, bone-patellar tendon-bone and hamstring tendon, respectively. At 7 months postoperatively, the patient had returned to playing rugby at the same level of play. The therapeutic strategy successfully met the established goals of returning to sports at the same level of play with excellent functional results after 2 years of follow-up. A literature review was performed via PubMed. The inclusion criteria were the studies in English language, assessing the return-to-sport after bicruciate ligament reconstruction in athletes. Eight studies were included in analysis. Only one study has focused on the return-to-sport in 24 competitive athletes and two other studies have included 1 professional athlete each. The overall rate of the return-to-sport after bicruciate reconstruction varied between 100% and 50%.
