This book comprehensively discusses anterolateral rotatory instability in the ACL deficient knee, exploring anatomy, biomechanics, diagnostics, clinics, surgical techniques as well as short and long term outcomes.

The author also offers an historical perspective ranging from the birth of modern anterior cruciate ligament surgery to the renewed global interest towards the role of secondary restraints and extra-articular reconstructions. Step-by-step guidance throughout each surgical technique further equips the reader to handle this complex condition.

Covering all theoretical and practical aspects, as well as future perspectives, this book is a must-read for all orthopedic surgeons and sports physicians wanting to gain insights into this promising field.
