WebDegenerative Meniscal Tears. Knee pain that arises with minimal or no trauma (for example – rising from a chair or getting out of a car). The most common age range for this to occur is between 40 and 60 years. The most common problem caused by a torn meniscus is pain.

The meniscus material only renews itself to a minor extent, so it is reduced with increasing age. The menisci become brittle and small cracks form. WebThe number of apoptotic cells were increased with tissue degeneration. On electron microscopy, the typical chromatin condensation in the OA meniscus was shown in apoptotic cell. The number of Fas-expressing cells was significantly higher in the OA meniscus(p 0.05). Nitrotyrosine immuno reactivity was prominent in the degenerative menisci(p 0.05). purely mechanical rockhampton
