With increase in longevity, more number of senior citizens demand a better quality of life. A painful knee can seriously hamper a person's capacity to walk freely and make him dependent not only on drugs to relieve pain but also on others for mobility. The solution to painful arthritic knee is now easily available in form of Knee Surface Replacement. Imagine yourself pushing a fully loaded vehicle which has flat tyres. You would need considerable force to make it move. Same happens to an overweight person with an Arthritic Knee Joint. Their knee joints feel stiff and are deformed and hence the person needs more physical energy to get up from a sitting position, walk, climb stairs and negotiate slopes. To overcome this, he or she takes medicine to relieve pain and muscle spasm and may use a support to walk, but as the age advances, the ability to overcome pain decreases making the person confined to bed most of the time. Prolonged use of NSAIDS (pain relieving medicines) can even damage the liver and the kidneys of the elderly person. For an individual aged above 60 years, having painful knee joints which hamper day to day living, knee surface replacement is an ideal choice. With current state of progress in every field of medicine, conditions like diabetes, hypertension, cardiac insufficiency are no more contraindications for surgery. Even obesity is not a problem.
