Knee Replacement surgery is a surgery performed for disabling arthritis of the knee joint. When the pain from knee arthritis starts hampering a person’s day-to-day life, and non-surgical methods fail to give lasting relief, it is the best time to consider the surgical option of either a partial or a total knee replacement. Although it is generally preferred to undergo surgery after the age of 55-60 years, there is no ideal age. The goal of performing a knee replacement is to reduce pain, improve one's quality of life and maintain fitness. There is one main concern of performing a Total Knee Replacement in younger patients, is that over time, the replaced knee can wear off and a revision surgery could be required. One of the factors that determine the longevity of the implant is the use and loading of the joint.
