“…Meniscal tears showed no significant associations in either cohort. Bone marrow lesions are known to be a consequence of acute injury and trauma, especially after fractures [30] and anterior cruciate ligament (ACL) rupture [31]. Very few studies have looked at the long-term risk of developing BMLs after a knee injury.…”

History of knee injury and MRI-assessed knee structures in middle- and older-aged adults: a cross-sectional study

The aim of this cross-sectional study was to describe the associations between history of knee injury and knee structure using magnetic resonance imaging (MRI). This study included two population-based samples: the Tasmanian Older Adult Cohort (TASOAC) study (n = 430; mean age, 63.0 years; range, 51-79 years; 51 % female) and the Offspring study (n = 372; mean age, 45.0 years; range, 26-61 years; 57.5 % female). In both studies, 1.5 T MRI scans of the right knee were performed to measure bone marrow lesions (BMLs), cartilage volume, tibial bone area, cartilage defects and meniscal pathology. History of knee injury was assessed using a self-administered questionnaire. The association between knee injury and knee structure was determined using multiple linear and log binomial regression models. Nineteen percent of the middle-aged and 12 % of the older adults reported a history of knee injury. In middle-aged adults, BML presence (prevalence ratio (PR) = 1.6 (95 % CI, 1.2; 2.1)), tibial bone area (difference of means (DM) = +86 (+23, +149)) and meniscal extrusion presence (PR = 2.7 (1.1, 6.8)) were significantly higher in those with knee injury. In older adults, cartilage defect presence (PR = 1.3 (1.0, 1.7)), lateral (DM = -265 (-439, -92)) and total tibial (DM = -325 (-600, -51)) cartilage volume, BML presence (PR = 1.4 (1.0, 1.9)) and tibial bone area (DM = +140 (+19, +260)) were significantly associated with knee injury. Meniscal tears showed no significant associations in either cohorts. The association between knee injury and MRI-assessed structural pathology in the knee joint is moderate and appears to be stronger in older adults compared to middle-aged adults.

“…This bone marrow edema is precisely localized at the site of ligamentous attachment, especially the deep meniscofemoral fibers of the medial collateral ligament (MCL) (see clinical case 3 [ Fig. 2C]), and may reflect reactive change or traction transmitted to bone by the partially torn ligament [10,11].…”

MRI findings can reveal the traumatic mechanisms in many acute knee injuries. By applying a biomechanical approach in MRI interpretation, it is possible to use easily detected lesions, such as osseous contusion and ligament rupture, to predict subtle but important abnormalities that might otherwise be missed. This systematic focused analysis enables a more accurate and rapid interpretation of knee MR studies.

“…At the acute or subacute onset, a localized pattern of bone marrow edema adjacent to the avulsion site is usually present (Fig. 1d) [2,3] and may become the diagnostic clue when displacement of the avulsed fragment is minimal. Finally, MR imaging may help to detect associated soft tissue injuries including meniscal tears and ligamentous injuries.…”

“…Secondly, a pattern of localized bone marrow edema may associate with acute avulsion fractures [2]. Magnetic resonance imaging has proved useful in distinguishing avulsion from impaction bone marrow edema patterns, based on the different extension of the edema in both entities [2,3]. Finally, MR imaging may facilitate interpretation of mechanism of injury and recognition of associated soft tissue abnormalities in both acute and chronic conditions, thus allowing a more thorough evaluation of the patient [2,3,4].…”

Avulsion fractures and chronic avulsion injuries of the knee: role of MR imaging

et al. 2002

View full text Add to dashboard Cite

Avulsion fractures and chronic avulsion injuries of the knee are common lesions in sports-related trauma, especially among adolescents. Magnetic resonance imaging may prove useful in detecting and characterizing such lesions, and has several advantages with regard to other imaging modalities. We review, illustrate, and discuss the MR imaging features of some of the more frequent avulsion fractures and chronic avulsion injuries of the knee, including avulsion fractures of the cruciate ligaments, avulsion fractures of lateral and medial stabilizers, avulsion fractures and chronic avulsion injuries of the extensor mechanism, and avulsive cortical irregularities of the distal femur. The role of MR imaging in evaluating such lesions is emphasized.
