This site is devoted to providing access to concise and unbiased information related to Total Knee Replacement and Knee Replacement Surgery. Here you will get an in-depth, yet easy to understand overview of the knee replacement operation as well as the implants used in Total Knee Replacement.
Total Knee Replacement, which is also known as Total Knee Arthroplasty, is a surgical procedure where:
In a normal knee, the ends of the bone are covered in a shiny, ultra-low friction material known as articular cartilage. If these surfaces become worn (as in osteoarthritis), joint pain and limited mobility may result. The X-ray on the right is that of a knee where osteoarthritis is present. Note the close proximity of the two large bones. In a normal knee, a clear, evenly spaced "gap" between the bones (the femur and tibia) would be observed. This "gap" is actually a healthy layer of articular cartilage which in an X-ray, is not visible. In the X-ray shown here, the cartilage has been worn away allowing the visible bony surfaces to come painfully in contact with one another.
Often, the surfaces of the bone will wear unevenly causing a bow-legged (varus) or knock-kneed (valgus) deformity. In an X-ray, this is seen as a “gap” on one side and a small or “closed-gap” on the other side.
If the pain and deformity become severe enough, Total Knee Replacement may be indicated....
