Over 50 per cent of the population has arthritis in one or more of their joints. By the time you are 75 years old, there is an 85 per cent chance that you will have developed arthritis somewhere, particularly in the larger joints such as the hip or knee. Treatment of arthritis can be either medical, with the provision of drugs and other n-invasive therapies, or surgical. The purpose of this book is to look at the various surgical solutions. Despite the frequency of surgery, there are few places a patient may go to learn about the relative merits and disadvantages of surgery; we hope this book will help fill that gap.
