Your knee joint is the largest joint in your body and also a very complex one. Because it is very important for your daily activities and you use it a lot, it can get injured and damaged.

Your knee joint is made up of:

3 bones	Thigh bone (femur), shinbone (tibia) and knee cap (patella).
Cartilage	Thin covering which keeps bones apart and provides a smooth, slippery surface for painless, free movement of your knee.
4 Ligaments	Thick rubber-bands like structures that holds the two bones together and provide stability.
2 Menisci	C - shaped cushions between the femur and tibia which act as shock absorbers.

Your knee can get damaged due to accidental fall, twisting, injury while walking, running, playing sports. Arthritis - damage and wear of the cartilage can occur due to Osteoarthritis, Rheumatoid Arthritis, Previous Injury, Fracture or Dislocation.

Cartilage damage	Early arthritis, osteonecrosis and injuries may lead to cartilage damage of a limited area leading to pain, stiffness, swelling and difficulty in performing daily activities such as walking, standing, sitting for long, climbing stairs and sitting cross legged.
Meniscal tear	Results from injury, when one excessively bends the knee as in squatting, or due to twisting. Apart from pain, swelling, stiffness and difficulty in walking, there may be 'locking'.
Ligament tears	Sports injuries or accidents may cause ligaments to tear causing instability and 'giving way'.
