Acute meniscal tears occur after the rotatory trauma of the knee, whereas chronic degenerative meniscal tears often occur in the elderly after minimal rotatory trauma or stress on the knee. In older adults, attritional changes in the meniscus lead to fragmentation of the meniscus and a variety of tears (usually occur at the posterior horn of the me...
On plain radiographs, meniscal tears are not visible. In rare cases secondary signs can be seen, such as a soft tissue swelling next to the meniscus when a meniscal cyst is present 4. Only when associated with more complex injuries plain film may suggest a meniscal tear, e.g. arcuate sign, reverse Segondfracture, tibial plateaufracture. With a sens...
Surgical arthroscopy is done in most cases. Meniscopexy or complete or partial meniscectomy can be performed, depending on the degree and type of meniscal tear.
The differential can be variable, depending on the type of tear but in general, consider: 1. meniscal degeneration(can be associated with a tear) 2. meniscal contusion 3. discoid meniscus 4. meniscal flounce(rare) 5. ring meniscus(rare) 6. meniscal ossicle(rare)
