Meniscal Injuries

The meniscus acts as a shock-absorber or cushion inside the knee.

The meniscus is located between the femur (thigh bone) and the tibia (shin bone). There are two menisci in the knee, the medial meniscus (inside of the knee) and the lateral meniscus (outside of the knee). The menisci are made of fibrocartilage, a special type of cartilage. They function as shock absorbers and force distributors that help to stabilize the knee.

Meniscal tears can present with pain to the knee as well as symptoms of clicking, catching and locking.  Because of the poor blood supply to the meniscus, the majority of meniscal tears are unable to heal on their own.

In patients who continue to have pain and symptoms despite conservative treatments, surgery interventions such as a partial meniscectomy (excision) can be performed.  This is an outpatient surgery with an arthroscope (a camera used to look into the joint) and two or three small incisions around the knee to look and work inside.  In rare cases and depending on the location of the tear, a meniscal repair can also be performed arthroscopically.
