This is most often due to wear and tear of the knee joint and is age- and activity-related. Osteoarthritis may also be due to previous injuries of the knee as well as pre-existing malformations.
This condition often affects individuals over the age of 50 but with increasingly active lifestyles, even younger people may be affected.
In the early stages, sufferers can seek pain relief from knee arthritis with activity modification, medications and other non-surgical means. However in more severe cases, surgery may offer the best chance of long-lasting results, and this may range from simple procedures such as arthroscopy, to more complex operations, such as realignment surgeries and knee replacement.
