The Causes of Knee Osteoarthritis
The precise cause of knee osteoarthritis is not known. There are two main factors that contribute to the development of knee osteoarthritis. These are being overweight and of mature age.
The joints in the knees support weight bearing so if a person is overweight then the chance of developing knee osteoarthritis increases. Almost 2 out of 3 overweight people develop knee osteoarthritis but even losing a few pounds will reduce the risk of this happening.
Knee osteoarthritis can develop at any age during adulthood but the chances increase from the age of 45 and beyond. This is due to the wear and tear of the joint and thinning of the cartilage over the years which leaves it open to developing osteoarthritis. This condition is known as ‘the degenerative joint disease’ due to deterioration of the joints.
There are many other factors that can lead to developing knee osteoarthritis, such as:
Above is a list of the factors that may lead to knee osteoarthritis but this doesn’t mean that these are the causes. People could have the above factors and never develop this condition and vice versa, there could be people who have nothing from above but still end up with knee osteoarthritis.
If knee pain comes about out of the blue then it is probably from an injury or trauma than knee osteoarthritis. If the skin around the joint turns red or hot then this could be from an infection which needs to be checked out by a medical practitioner as soon as possible.
