“…On the con trary its use for detection of chondral lesion is less widely accepted; although it is very accurate for deep chondral defects (accuracy superior to 90% for the grades III and IV of the ICRS classification (3)), it is much less sensitive for ICRS grades I and II lesions (4). This means that morpho logical MRI shows chondral damage joint (9).…”

“…16,26,27 Whether or not MRI underestimates the number and size of cartilage lesions of the knee joint is a point of controversy. 28 There is general agreement that cartilage damage evaluation on standard MRI examination remains problematic. However, recently developed cartilage- specific MRI sequences were able to demonstrate, depending on the severity of the lesion, a sensitivity of 43-87% and a specificity of 89-97%.…”

“…However, several studies report cartilaginous lesions occurring preferentially in the medial compartment and/or in the medial femoral condyle. 1,12,28,31,[37][38][39][40] To recognize age-specific differences, patients were divided into two age subgroups: (A) subjects aged 18-50 years and (B) subjects aged 51-81 years. The majority of grade I lesions occurred in Group A (65%).…”

Objective: Arthroscopy is "the gold standard" for the diagnosis of knee cartilage lesions. However, it is invasive and expensive, and displays all the potential complications of an open surgical procedure. Ultra-high-field MRI now offers good opportunities for the indirect assessment of the integrity and structural changes of joint cartilage of the knee. The goal of the present study is to determine the site of early cartilaginous lesions in adults with non-traumatic knee pain. Methods: 3-T MRI examinations of 200 asymptomatic knees with standard and three-dimensional doubleecho steady-state (3D-DESS) cartilage-specific sequences were prospectively studied for early degenerative lesions of the tibiofemoral joint. Lesions were classified and mapped using the modified Outerbridge and modified International Cartilage Repair Society classifications.Results: A total of 1437 lesions were detected: 56.1% grade I, 33.5% grade II, 7.2% grade III and 3.3% grade IV. Cartographically, grade I lesions were most common in the anteromedial tibial areas; grade II lesions in the anteromedial L5 femoral areas; and grade III in the centromedial M2 femoral areas. Conclusion: 3-T MRI with standard and 3D-DESS cartilagespecific sequences demonstrated that areas predisposed to early osteoarthritis are the central, lateral and ventromedial tibial plateau, as well as the central and medial femoral condyle. Advances in knowledge: In contrast with previous studies reporting early cartilaginous lesions in the medial tibial compartment and/or in the medial femoral condyle, this study demonstrates that, regardless of grade, lesions preferentially occur at the L5 and M4 tibial and L5 and L2 femoral areas of the knee joint.

“…La sensibilidad de la RM es directamente proporcional a la magnitud en cuanto a superficie condral comprometida y profundidad de la lesión (2) . Por otro lado los cartílagos de mayor grosor como los de la rodilla son más fáciles de evaluar que lo cartílagos de aquellas articulaciones más pequeñas.…”

Articular cartilage injuries is a common event and imaging technique has become increasingly important in diagnosing them. Magnetic Resonance Imaging (MRI) is the imaging method of choice for the evaluation of chondral lesions. This article reviews the usefulness of this method compared to conventional as well as to advanced quantitative studies, thus enabling evaluation of initial cartilage alterations before being evident in normal MRI sequences. Keywords: Articular cartilage, Chondral lesions, Magnetic Resonance Imaging. RESUMENLas lesiones del cartílago articular son frecuentes y su diagnóstico por imagen cada día más importante. La resonancia magnética es el método de diagnóstico por imagen de elección para la evaluación de lesiones condrales. Este artículo revisa la utilidad de este método, en relación a estudios convencionales así como también estudios avanzados, cuantitativos, que permiten evaluar alteraciones condrales iniciales antes de ser evidentes en secuencias habituales de resonancia magnética. Palabras clave: Cartílago articular, Lesiones condrales, Resonancia magnética. INTRODUCCIÓNLas lesiones de los cartílagos articulares son frecuentes en las distintas articulaciones y sus etiologías multifactoriales, incluyendo causas traumáticas, artropatías inflamatorias, infecciosas (artritis séptica) y causas degenerativas. Las lesiones de origen degenerativo son las más frecuentes, siendo un problema de salud pública importante por el alto costo económico y social que representan los gastos directos o indirectos en relación al tratamiento y ausencia laboral. Se calcula que aproximadamente el 75% de la población mayor de 75 años presentan artrosis (1) . El cartílago articular o cartílago hialino es de vital importancia en las articulaciones de tipo diartrosis (articulaciones con amplio rango de movimiento) y sus funciones principales son disipar y transmitir las fuerzas sobre las superficies articulares, amortiguar las cargas y proveer una superficie de deslizamiento adecuada entre las superficies articulares. Como características principales el cartílago hialino es un tejido avascular (se nutre a través del líquido sinovial), no tiene inervación y no tiene capacidad de regenerarse con el mismo tejido, solo presenta capacidad reparativa limitada con fibrocartílago, el que es de menor resistencia.
