Knee arthroplasty or knee replacement surgery is a procedure which is aimed at the replacement of the damaged surfaces of the knee joint with an artificial prosthesis to relieve pain and disability. It is performed when the knee joint is affected by osteoarthritis, psoriatic arthritis and rheumatoid arthritis. Knee arthroplasty can be total or partial. Total knee arthroplasty is intended to correct bone and knee joint trauma, or correct varus deformity or mild valgus. Obesity is often seen to present complications in total knee arthroscopy, and therefore bariatric surgery is recommended in morbidly obese patients. This book elucidates the concepts and innovative models around the techniques of total knee arthroplasty. It strives to provide a fair idea about this operative procedure and to help develop a better understanding of the complications involved in this surgery, and their management strategies. For all readers who are interested in orthopedics and orthopedic surgery, the case studies included in this book will serve as an excellent guide to develop a comprehensive understanding.
