Torn meniscus symptoms Symptoms are usually sudden onset, however, can develop gradually over time. A magnetic resonance imaging (MRI) scan is often used to diagnose meniscal injuries. The meniscus is a piece of C-shaped cartilage that helps cushion the knee. If mechanical symptoms are present in this subset of patients, a partial or subtotal meniscectomy may improve symptoms; although, these tears are not usually associated with traditional meniscal-based mechanical symptoms. Trauma to medial collateral ligament usually also involves medial meniscus. The preferred nomenclature for this tear pattern is: A gradient-echo T2*-weighted sagittal image, A. Sometimes these tears require surgical repair. Most commonly it is impossible to fully extend the knee; more accurately described as stiffness (termed 'pseudo locking') due either to a small effusion (requiring increased force to bend the tense joint capsule) or to pain inhibition as the femoral condyle compresses the torn meniscus. In the early days of MR, it was often felt that the role of MR was simply to identify whether a tear was present or not, and treatment of meniscal tears was largely composed of operative resection. If you undergo surgery it will likely be followed by physical therapy to optimize knee strength and stability. Athletes, particularly those who play contact sports, are at risk for meniscus tears.

A recent study demonstrated 46% of patients with degenerative meniscal tears elected not to have surgery after 4 weeks of nonoperative treatment, and their functional improvement matched patients in the operative group.21 Another study of degenerative tears demonstrated that supervised exercise caused the same reduction in knee pain and the same increase in function and satisfaction as partial meniscectomy plus exercise.23 As degenerative tears are more common in elderly patients, this group is more likely to respond to conservative treatment. Fat-suppressed coronal images demonstrate before and after images following repair of a bucket handle tear. Inferiorly Displaced Flap Tears of the Medial Meniscus We believe these tears are more degenerative in nature, and there is no evidence to support that by repairing these medial meniscal root tears, knee degeneration will be postponed or stopped.

Conservative management is important in all patients with acute rest, intensive rehabilitation with physiotherapy and modification of activity. Those that extend through the entire width of the meniscus are particularly harmful (16a,16b), and even if such tears appear stable following repair, they are unlikely to regain the ability to provide hoop stress to the meniscus.13 Radial tears have therefore classically been treated with partial meniscectomy, though evolving surgical techniques have led to successful reports of the repair of radial tears that communicate with the meniscal periphery.11 A recent report has even described the successful repair of radial tears of the medial meniscal root,14 utilizing a tibial tunnel through which sutures are placed in the avulsed meniscus, a technique similar to that used in patients undergoing meniscal transplantation. Meniscal pain occurs during torsional, weight bearing knee movements (classically pivoting on the knee while walking) as a sharp stab lasting several seconds, often followed by a dull ache for several hours.
