The knee meniscus is tough fibrocartilage that is positioned between the thigh(femur) and shin bone(tibia).
Each knee has a two meniscus: lateral and medial. They are C shaped.
They function as a shock absorber protecting the delicate cartilage in your knee.
Injury can result in a meniscal tear. There are several different types: horizontal, radial, oblique and longitudinal.
Surgery is often recommended despite the fact that 60% of meniscal tears are not associated with pain.
Menisectomy is where a portion of the “damaged” meniscus is surgically removed. While the “damaged” area is removed often patients fail to obtain significant pain relief. Furthermore studies have demonstrated that menisectomies increase the rate of cartilage loss in the joint. This make sense since by removing a portion of the shock absorber, the forces of daily living are transmitted to the delicate cartilage. The cartilage was not intended to bear this increased stress and therefore starts to degenerate.
