Meniscal tissue has been removed from your knee joint.

In the knee joint, the thighbone (femur) is connected to the shinbone (tibia). Between the two bones are two pieces of crescent-shaped cartilage. These pieces of cartilage and fiber are the menisci. There is a medial meniscus and a lateral meniscus. The medial meniscus is on the inside of the leg, while the lateral meniscus is on the outside of the leg. The menisci perform various functions. They balance out any unevenness in the joint surfaces of the bones. The menisci also act as shock absorbers. They absorb violent shocks.

Your meniscal tissue was removed via an arthroscopy. An arthroscopy first involves making a small incision in the skin. A camera was pushed through this incision. This camera sends images of the inside of the joint to a screen. Instruments such as forceps and scissors can be inserted into the joint through other small incisions.

The arthroscopy can involve removing tissue from one or both menisci. For example, damaged parts of a meniscus can be removed or the surface of the meniscus can be smoothed out. The meniscus concerned is not completely removed, however.
