Health technology assessment of magnetic resonance imaging of the knee. (Eur J Radiol. 2008) "For the detection of meniscal injury, MR has the same accuracy as arthroscopy and should be performed in order to avoid unnecessary surgical interventions. A negative MR also obviates further investigation in suspected cartilage damage. This is not true for anterior and posterior cruciate ligament problems where MRI is less accurate than clinical investigation."

High-resolution Magnetic Resonance Imaging and Conventional Magnetic Resonance Imaging on a Standard Field-strength Magnetic Resonance System Compared to Arthroscopy in Patients with Suspected Meniscal Tears. (Acad Radiol. 2008 ) “CONCLUSION: High-resolution MRI, using a surface dual-loop coil and specific sequences, which can be performed on every standard-field-strength MRI scanner, is able to significantly improve diagnostic performance for the detection of a meniscal tear of the knee joint.”

Pathologic characteristics of the torn human meniscus. (Am J Sports Med. 2007 ) “CONCLUSION: Patient age had a significant effect on the cellularity of the torn meniscus, with patients older than 40 years having significantly fewer meniscus cells than did those younger than 40 years. Further studies are needed to define the relative importance of the individual histologic findings in the clinical setting of meniscus tear and repair. CLINICAL RELEVANCE: In light of their decreased cellularity, menisci from patients older than 40 years may be more vulnerable to degeneration and retear after repair than are menisci of younger patients.”

Physical examination tests for assessing a torn meniscus in the knee: a systematic review with meta-analysis. (J Orthop Sports Phys Ther. 2007 ) “CONCLUSIONS: No single physical examination test appears to accurately diagnose a torn tibial meniscus and the value of history plus physical examination is unknown. Differences between studies in diagnostic performance remain unexplained, presumably due to local differences in the way the tests are defined, performed, and interpreted. We recommend a more standardized approach to performing and interpreting these tests and the development of a clinical prediction rule to aid clinicians in the diagnosis of a torn tibial meniscus.”

Post-traumatic glenohumeral cartilage lesions: a systematic review. (BMC Musculoskelet Disord. 2008) “CONCLUSIONS: The great majority of glenohumeral cartilage lesions without any bony lesions are the results of overuse. Glenohumeral cartilage lesions with an intact subchondral bone and caused by an acute trauma are either rare or overlooked. And at increased risk for such cartilage lesions are active sportsmen with high shoulder demand or athletes prone to shoulder injury.”

Radial tear of the medial meniscal root: reliability and accuracy of MRI for diagnosis. (AJR Am J Roentgenol. 2008 )

Radial tears in the root of the posterior horn of the medial meniscus. (Knee Surg Sports Traumatol Arthrosc. 2008 ) “Radial tears in the root of the medial meniscal posterior horn, which may not be visible in about one-third of the preoperative MRI scans, are common. That type of meniscal tear is strongly associated with obesity and older age and is morphologically different from the degenerative tears that often occur in the posterior horn. Partial meniscectomy provides symptomatic relief in most cases but does not arrest the progression of radiographically revealed osteoarthritis.”

Knee Injury - Meniscus Cartilage Tear (Patient UK)

Medial Cartilage Meniscus Injury “Each knee joint has two crescent-shaped cartilage menisci. These lie on the medial (inner) and lateral (outer) edges of the upper surface of the tibia (shin) bone. They are essential components, acting as shock absorbers for the knee as well as allowing for the proper interaction and weight distribution between the tibia and the femur (thigh bone). As a result, injuries to either meniscus can lead to critical impairment of the knee itself.”
