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'.|
