Anatomy of Knee Arthritis – Meniscus

knee meniscus

knee meniscus

The menisci of the knee joint is a crescent-shaped cartilage structure that disperses friction in the knee joint.  The knee menisci is flat on the bottom and concave on the top.  The menisci of the knee is divided into two parts: medial (inside) and lateral (outside).  Both sides of the menisci provide structural strength to the knee when tension and torsion are applied to it.

When the meniscus is injured doctors either repair it or remove part of it.  It depends on where the tear is located, the age of the patient, and the skill of the doctor.  Either a repair or removal of the meniscus can lead to osteoarthritis.
