This book approaches the ACL deficient knee from a different perspective than those of the previous classical ways. The common approach is the analysis of closed compartments; anatomy, biomechanics, physical findings, imaging, surgical treatment and rehabilitation. The approach of this book is completely opposite, focusing on questions, controversies, problem analyses and problem solving, besides analyzing the possibility of prevention. Therefore, in each chapter, the biomechanics, anatomy, and other areas that are relevant to the topic are reviewed. There are chapters where highly specialized surgical techniques are presented (acute ACL repair, double bundle reconstruction, chondral lesions treatment or meniscal transplant). These chapters are written by internationally renowned specialists that are pioneers in the topic analyzed. Another interesting aspect of this book are the step by step surgical techniques videos, that will allow a knee specialist to perform the technique presented by the author. Moreover, the videos will include anatomy and physical therapy techniques.

Among all the extensor mechanism pathologies, lateral patellar instability is of great interest not only for the knee specialist, but also for the general orthopedic surgeon and trainee. The procedure that is most frequently performed to treat lateral patellar instability is the medial patellofemoral ligament (MPFL) reconstruction. The reason for this great interest in this procedure is obvious. Medial patellofemoral ligament reconstruction is the most frequently performed procedure in the extensor mechanism. It also is the most predictable and has the best clinical results of all the procedures in the extensor mechanism. In this handbook we analyse the different reconstruction techniques, step by step, for the MPFL reconstruction, as well as other techniques less frequently used in the patient with lateral patellofemoral instability. We also analyse the treatment of medial patellofemoral instability. It is a very practical book, aimed at the general orthopedic surgeon and also the ones specialized in the knee.
