The menisci in the knee joint can be torn for a variety of reasons. Considering the structure of the menisci, would you expect these tears to heal on their own? Why or why not?

a.The medial meniscus is attached to the tibial collateral ligament, so fibroblasts in the ligament can divide and differentiate into chondrocytes to repair the meniscus.

b.Menisci tears do not heal on their own because the menisci are composed of hyaline cartilage and do not have an extensive blood supply.

c.Menisci tears do not heal on their own because the menisci are composed of fibrocartilage and do not have an extensive blood supply.

d.Menisci tears can heal quickly because of the nutrients surrounding them in the synovial fluid.

Expert Answer

Step 1

Meniscus are the two wedge shaped pieces of cartilage in our knee joints are acts as shock absorbers. They present between the thighbone and the shinbone. They are rubbery and tough in nature and helps to cushion the joint and keep the joint stable.

Step 2

 Considering the structure of menisci, the process of heal on the tears their own is depend upon the region of tear. Meniscus has two distinct regions Red zone and White zone. Red zone has rich blood supply, tear in red zone can heal its own because of blood supply.

While the white zone doesn’t have blood supply, and this region would not heal its own.

Step 3

Options given in the question are described below:

Option (a)- This option is incorrect because tear of meniscus can be repaired if it is on the outer one – third of the meniscus. And in the outer part of meniscus, rich blood flow is present, blood cells can regenerate meniscus tissue or heal it. There is no involvement of tibial ligament in meniscus tear healing.

Option (b)- this option is not correct because menisc...
