Meniscal Tears

A meniscal tear is an injury inside the knee joint often caused by twisting or turning while the foot is planted. It can occur in sports or everyday activities. Meniscal tears can be part of the degenerative changes in the knee associated with arthritis and are managed differently to acute sporting injuries.

Anatomy

The knee contains two menisci — a medial (inner) and a lateral (outer) meniscus. These C-shaped pieces of meniscus act as shock absorbers between the thigh bone (femur) and shin bone (tibia), helping to distribute weight and stabilise the joint.
