A picture is worth a thousand words, and the goal of this atlas is to better understand patellofemoral conditions through pictures. Hence the reason we have decided to publish this book,  which is a collection of the finest images of patellofemoral joint surgery, ​supplied by world renowned specialists in Knee surgery. 
All the images, footnotes and summaries are compiled in order to convey a simple understanding of this complex problem. This is a very practical book, aimed at the general orthopedic surgeon and also those that specialize in surgery of the knee.

The book is divided into four sections, the first section focuses on the etiopathogenic bases, the second section focuses on emerging technologies, the third section includes difficult clinical cases

studied, and the fourth section provides a description of the most important surgical techniques for the knee extensor mechanism.
