How can a meniscus be torn?
The medial and lateral menisci are fixed between the two weight-bearing surfaces within the knee, and as such can become “pinched” by the other structures of the knee between the joint when an injury occurs. Typically, the injury involves twisting on a bent knee. When this happens the menisci can become torn (“torn cartilage”). Any form of physical movement can potentially cause a meniscal tear, although they tend to be associated with sporting activities. A classic example is of a footballer tackling another player, but meniscal tears can occur following everyday pursuits, such as gardening or even just taking a long walk.
