Age – the cartilage gets more brittle as age advances and their capacity to repair themselves becomes low. With age, arthritis can develop.

Weight – as joint damage depends to some extent on the load the joint supports, excess body weight may result into arthritis. It is particularly true in case of knees and hips that worn out faster in heavier people.

Previous injury – damage to the joints may result into irregularities. Previous injuries can be a part of knee arthritis cause, where the broken bone area enters the knee joint cartilage.

Occupational dangers – in some particular occupations, the workers are prone to greater risk of developing arthritis like heavy construction and assembly line workers.

Infection or illness – people experiencing joint infection, other medical conditions or several episodes of gout may possibly develop knee arthritis.

  • Avoid kneeling – kneeling at work, home or church is a knee killer. It puts pressure on the front knee where arthritis is seen under the knee cap. Hence, it is suggested to avoid kneeling.
  • Don’t carry heavy loads – each extra pound carried or lifted by you exerts pressure and increase stress on the arthritic knee. You can take help form your family or friends or make use of assistive tools and devices in this case.
  • Avoid standing longer – if you stand for long hours, lot of stress is put on the knees. This may not be felt at that moment; however, you may experience it later. The standard rule is standing for one hour at a time. Then, take a break or sit for some time and then stand again, if needed.
  • Using both hands for support – while getting up from a sitting position, make use of both your arms and hands to push down and lift yourself slowly. This will decrease the stress on the bent knee and decrease further damage or pain.
  • Stretching the legs – keep your legs in motion and change its position often when seated. Never fold the legs under the chair, since it exerts more pressure on the knees.
  • Do not walk up or down hill – if possible, avoid going to up or down hills, since flat surfaces do not put any pressure on the knee arthritis, but an incline does.
  • Avoid stairs, use elevator – stair steps put strain to the arthritic knees. So, wherever you have an option of elevator over steps, do prefer them.
