Osteoarthrosis or osteoarthritis basically means wear and tear of the cartilage, which can be divided into primary (due to the normal ageing process - happens to almost every one universally) and secondary - due to a preexisting cause, disease , trauma or condition from birth. One must understand that primary osteoarthritis is more prevalent in knee joints in Asian population, due to lifestyle habits and in the West, a higher prevalence of osteoarthrosis of hips has been found as compared to Asian population.
Osteoarthritis affecting the knee joint - is universal and part of ageing process , cartilage is a tissue with a very low metabolic activity and hence cant be regenerated at a pace which can outrun its wear. Knee as a joint is abnormally shaped and unlike the ball and socket of the hip it is primarily designed to bear weight and provided stability but makes it vulnerable for wear. The wear happens more on the inner aspect of knee and later cases affects whole of knee joint resulting in pain in the whole of knee .
Therapies which work only in early osteoarthritis of knee are - Cartilage regenerating medication (dyacerin , glucosamines), viscosupplementation with hyaluronic injections , physiotherapy and analgesics. But one should know these things may prolong and help an individual to be pain free for a maximum of few years, and if lucky with activity modifications a good number of years.
Treatment for advanced osteoarthritis- High tibial osteotomy,uni knee replacement and Total knee replacement -is still the gold standard and only available option which has stood the test of time and which stands to reason for patients with advanced arthritis.
Questionable therapies exist widely all around the world which do not hold water,do not stand to reason for the simple fact that - no one can reverse ageing of a worn out cartilage, despite what ever the advance in science.
