A tear of a meniscus is a rupturing of one or more of the fibrocartilage strips in the knee called menisci. When doctors and patients refer to "torn cartilage" in the knee, they actually may be referring to an injury to a meniscus at the top of one of the tibiae. Menisci can be torn during innocuous activities such as walking or squatting.
Injuries to the ACL are common, 250,000 ACL injuries occur on an annual basis. This corresponds to a 1 in 3,000 chance of an individual sustaining an ACL injury. Ligaments in the ACL or meniscus are usually torn with an external force being applied to the knee joint. The ACL can be torn without an external force being applied [11]

A bucket-handle tear of the knee is a specific type of meniscal injury characterized by a longitudinal tear of the medial or lateral meniscus, where a displaced inner fragment resembles the appearance of a "bucket handle". [1]
ACL injuries can be categorized into groups- contact and non-contact based on the nature of the injury [6] Contact injuries occur when a person or object come into contact with the knee causing the ligament to tear. However, non-contact tears typically occur during the following movements: decelerating, cutting, or landing from a jump.
Damage to the outer third of the meniscus has the best healing potential because of the blood supply, but the inner two thirds of the medial meniscus has a limited blood supply and thus limited healing ability. Large tears to the meniscus may require surgical repair or removal. In terms of a meniscus tear, the doctor can categorize the injury ...
However, recent research has called into question whether many meniscus tears actually cause pain or are simply part of the normal degenerative process of aging. A 2008 study in the New England Journal of Medicine which shows that about 60% of meniscus tears cause no pain and are found in asymptomatic subjects. [1]
