Arthroplasty is a surgical procedure within the domain of orthopedics. In this procedure, the articular surface of a musculoskeletal joint is replaced, remodeled or realigned by osteotomy. The aim of arthroplasty is to relieve pain and restore function to the joint after damage by arthritis or some other type of trauma. The most successful and common form of arthroplasty is the joint replacement arthroplasty. Other types of arthroplasty include interpositional arthroplasty, excisional arthroplasty, resurfacing arthroplasty, mold arthroplasty, etc. However, arthroplasty can cause various complications, such as deep vein thrombosis, infection, bleeding and periprosthetic fracture. The prosthesis selected in arthroplasty must be non-toxic yet resistant, compatible and durable. The technology has been improved in the recent years with a porous-coated prosthesis which helps in bonding to the body. This book strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field. It consists of contributions made by international experts. This book is a vital tool for all researching or studying arthroplasty as it gives incredible insights into emerging trends and concepts.
