Osteoarthritis is a degenerative joint disease where cartilage in the joints wears down over time, leaving bone rubbing on bone. It can affect any joint in the body, but most commonly affects the hands, hips, knees, neck, and lower back.


  • Joint pain during movement
  • Tenderness while applying light pressure
  • Stiffness, especially after waking up or after a period of inactivity
  • Loss of flexibility and ability to move the joint through its full range of motion
  • Hearing or feeling a grating sensation
  • Bone spurs form around the affected joint can add pain and feel like hard lumps

Common causes:

  • Aging
  • Joint injury or stress
  • Heredity
  • Muscle weakness
  • Obesity
  • Poor posture or body mechanics
  • Repetitive disuse or misuse of joints

Risk Factor:

  • Age - increases over age 40
  • Gender - women are at a higher risk
  • Bone deformities - malformed joints from birth can increase degeneration
  • Obesity - more stress on the weight-bearing joints
  • Occupation - repetitive stress on a particular joint may predispose the joint toward developing osteoarthritis
  • Deconditioning
