The knee is one of the main weight-bearing joints in your body.
The knee consists of :
  • Your thigh bone (femur) which turns on the upper end of the shin bone (tibia)
  • Your kneecap (patella) which slides in a groove on the end of the thigh bone.

A healthy knee requires intact articular cartilage (the smooth surface lining the end of the bones); intact meniscii (two protective "cushions" inside the joints); intact ligaments (structures inside and outside the joints that keep the knee stable); and, good muscle control.

What causes knee pain?

Knee pain is sometimes caused by deformity or injury, but one of the most common causes is osteoarthritis (OA), also known as degenerative joint disease. In a joint that has been damaged by arthritis, the cartilage wears down, causing bone to rub against bare bone, creating pain, stiffness, deformity and loss of mobility.

Other common causes of joint pain include rheumatoid arthritis or post-traumatic arthritis which you can read more about at www.drdeepakinamdar.com.
