Joint replacement surgery is one of the most revolutionary surgeries invented. It is the pinnacle of medical achievements, the breakthrough solution to joint pains. We have perfected the science of replacing human joint with artificially made parts over last several decades. Over these decades, we have understood the bio-mechanics of natural human joints better and examined the behavior of the replaced joint inside the human body very thoroughly. Culmination of these efforts and medical advancements in bio-materials is that we now have the solutions to resolve joint pain problems by replacing the very joint in a very safe, predictable and successful manner. Today, joint replacement surgery has become a commonly performed surgery by many well trained orthopedic surgeons across the world. The success of the surgery has been established by the fact that each year the number of surgeries performed or people choosing to undergo the procedure is increasing.

A joint replacement surgery is a procedure of replacing the damaged surfaces of a joint with a prosthetic implant. In common tongue, it can be termed as putting metallic cap on he damaged portion of the joint. The articular cartilage covering the joint surfaces is replaced with metallic or plastic material and the replaced parts articulate with each other.

The materials used for the prosthesis have been tested for their wear, fatigue resistance and bio-compatibility for years before they are finally approved for the use in the human body. As medical science improved and evolved over the years, our understanding of the properties of the materials used for joint replacement has grown significantly. The latest generation of implants have shown excellent durability, lower wear and fatigue. Their success has prolonged the life of the implant in the human body and most of the surgeries done in the patients in their 60s can last for lifelong without having to be revised later on.
