At closer look you will notice that the horizontal structure has a lower signal intensity than the meniscus and looks funny. femoral condyles (most common site;~95% of all cases): the high signal line demarcating fragment from bone usually indicates an unstable lesion however false positives can result from edema, low signal loose bodies, outlined by high signal fluid, donor defect filled with high signal fluid, high signal intensity rim at the interface between the fragment and the adjacent bone on T2-weighted sequences, high signal intensity line extending through the articular cartilage overlying the lesion, focal osteochondral defect filled with joint fluid, indicating complete detachment of the fragment, persistent pain with activity: occurs in ~66%following surgical management of the knee and in 40% following surgical management of the elbow, normal irregular distal femoral epiphyseal ossification, 1.

Ayurveda. When the fragment is unstable or displaced, without treatment patients are susceptible to premature secondary osteoarthritis. 1990;41(1):173-6. The location of a meniscal tear is of importance because tears in this vascular portion of the meniscus are more likely to heal spontaneously than tears in the avascular portion or white zone of the meniscus. Radiographics. WebDiagnosis is made radiographically with displaced injuries but CT/MRI may be required to diagnosis nondisplaced fractures. 11. This is essential in determining management. 5/7: Anteriorly there is extrusion of the meniscus. Osteoarthritis of the knee. Notice displaced inner fragment of the meniscus. A Segond fracture has a high association with a tear of the anterior cruciate ligament (75-100%) and injuries of the medial and lateral menisci (66-70%). The condition usually spontaneously resolves once the physis closes. Over time, this can lead to symptomatic knee osteoarthritis. AY. The ACL is a band of dense connective tissue which courses from the femur to the tibia.It is considered as a key structure in the knee joint, as it resists anterior tibial translation and rotational loads.
