At MD Health in Doncaster, the allied health experts often help people with knee problems, especially injuries related to the menisci of the knee. The menisci are two C-shaped pieces of cartilage that sit inside your knee joint. They act as cushions between your thigh bone (femur) and shin bone (tibia), helping your knee move smoothly and absorb shock. When the menisci get damaged, it can cause pain, swelling, and trouble moving the knee.
