It is therefore quite important in treatment planning for the pre-operative MR to provide information that can be used to determine whether meniscal repair rather than partial meniscectomy is to be performed. Biomechanical studies have demonstrated that repair of medial meniscus posterior root tears leads to improved contact mechanics. How is Oblique Fracture Treated? There is a history of sudden inability to fully extend the knee, with a rotational flexion/extension 'trick' required to regain full extension. Oblique Tear | definition of Oblique Tear by Medical dictionary MR imaging is reliable in the detection of meniscal tears and identification of meniscal fragmentation and displacement [1, 2, 3, 4].Displaced meniscal fragments are often clinically significant lesions requiring surgical intervention and, therefore, are important to identify.
