Knee pain is the most common joint problem seen in older adults. Osteoarthritis is the leading cause of this. Learn more about this condition here.
Osteoarthritis (OA) is a chronic joint disorder in which there is progressive softening and disintegration of articular cartilage accompanied by new growth of bone at the joint margins and capsular fibrosis. Osteoarthritis may be asymmetrically or symmetrically distributed and often localized to only one part of the joint. It is related to abnormal loading. OA is a dynamic phenomenon; it shows features of both destruction and repair.
Age is the most common factor associated with OA. As one gets older, the cartilage, meant to prevent the articular bones from rubbing against each other, gradually starts to wear off causing reduction in the lubricant oil in the joint. This does not mean that age is the only factor that affects OA. OA is the commonest of all the conditions that affect the joints in particular. It is truly a universal disorder, affecting both sexes and all races. Everyone who lives a long enough life is expected to suffer from it sometime in their life.
Being a weight bearing joint, congenital bony disorders, trauma, certain occupations that cause repetitive stress on the knee, knee bending activities, weak bones, obesity, family history of OA are a few risk factors that increase the chance of getting OA.
Knee pain is usually the presenting symptom in the early stages. Other symptoms include stiffness, swelling, restriction of knee movements and difficulty in doing activities of daily living like getting up from a sitting position. The deformity may occur in late stages.
In late stages, progressive joint destruction, increasing pain, instability and deformity usually require treatment options like joint replacement. The destroyed joint is replaced by a new synthetic one. This knee replacement surgery has transformed the lives of millions of patients till now and continues to be a blessing for such patients.
