The meniscus is a fibro-cartilage located between the femur and the tibia. It is a structure that follows the femur and the tibia in the flexion-extension and rotational movements of the knee. It serves to make the knee more consistent, supports knee stability, and protects the articular cartilage of the tibia and the femur by better distributing the burden of the body weight.
There are two categories of meniscus injuries, acute (caused by trauma) or degenerative (caused by aging). Meniscus injury symptoms are pain when performing certain positions, painful limitation of knee motion, tear, lack of strength, and crackling or popping sounds.
Surgical treatment of a meniscal tear may be indicated if:
Symptoms are disabling
Symptoms persist for more than 2 – 3 months
A fracture causes knee locking
ACL associated rupture. In this case, the knee is unstable and there is excessive movement within the joint.
The patient is a high-level athlete
Through arthroscopic surgery, it is possible to make a partial resection of the meniscus and leave the remaining stable, fixed, consistent and non-degenerated part that partially allows the meniscus function. A magnifying optical device connected to a video camera is introduced to have a detailed view of the knee and define the characteristics of the injury to apply the required instruments.
