To help answer those questions we put together the following list of definitions for what each degree acronym stands for as well as explanations of the meanings behind all the different terminology. Here's a breakdown of some of the acronyms you'll find out there:
Meniscus Tears. Information on meniscus tears is also available in Spanish: and Portuguese: . Meniscus tears are among the most common knee injuries. Athletes, particularly those who play contact sports, are at risk for meniscus tears. However, anyone at any age can tear a meniscus. When people talk about torn cartilage in the knee, they are usually referring to a torn meniscus.
Each meniscus is curved in a C-shape, with the front part of the cartilage called the anterior horn and the back part called the posterior horn. There is also articular cartilage that lines the joint surfaces of the bones within the knee, including the tibia, femur, and kneecap (patella). The terminology torn knee cartilage refers to damage to one of the C-shaped menisci of the knee between the femur and tibia. As with any injury in the body, when the meniscus is damaged, irritation occurs. If the surface that allows the bones to glide over each other in the knee joint is no longer smooth, pain can occur with each flexion or extension.
