Patient discussion about meniscus

Q. I am scheduled for scope surgery for a torn meniscus on my knee and what is the duration for recovery? Has anyone had this surgery for a torn meniscus? How did you deal with this recovery?

A. The recovery process is individual, and you cannot predict it in advance. I know someone who has done it and was able to go back to exercising regularly after 2 months. I would think the recovery from the surgery itself is a matter of few weeks until you can walk properly, however you should still give your knee a break and rest for a while after.

Instead, it should be emended to represent ichnocoenoses comprising simple burrows, trackways, striate and bilobate pits, bilobate/trilobate burrows and trails, simple meniscate burrows, and vertical burrows (groups VII, VIII, X, XI, XII XIII in Tables 1 and 3).
Meniscate burrows (group XII), like resting traces (group X), represent mostly infaunal predation (Jensen 1990), scavenging, of fugichnial activity (from desiccation/salinity or temperature fluctuation/ predators/erosion).
