The Knee Instability Matrix: Rotatory Knee Instability: An Evidence Based Approach
A standard Anterior Cruciate Ligament (ACL) tear causes straightforward forward-and-back (sagittal) instability. However, when the injury involves the complex structures of the posterolateral or anterolateral corners of the knee, the joint develops a devastating “rotatory” instability—the knee literally twists and buckles out from under the patient when they pivot. Rotatory Knee Instability: An Evidence Based Approach is a fiercely specialized, highly biomechanical surgical manual dedicated to this complex, multi-planar failure. This volume provides the exact blueprints required to recognize and reconstruct the most unstable knees.
Mastering the Pivot Shift
The core philosophy of this text is three-dimensional joint control. The authors aggressively detail the biomechanics of the Anterolateral Ligament (ALL) and the Posterolateral Corner (PLC). It dictates exactly how to perform and interpret a pivot-shift test under anesthesia, using quantitative devices to measure the exact degree of rotatory subluxation that a simple anterior drawer test completely misses.
Navigating Complex Reconstructions
The book provides a masterclass in extra-articular surgery. It dictates the exact surgical pathways for performing a lateral extra-articular tenodesis (LET) or an ALL reconstruction in conjunction with a standard ACL repair. It rigorously analyzes the massive clinical trial data demonstrating that adding these extra-articular procedures drastically reduces the re-rupture rate in high-risk, pivoting athletes.
Frequently Asked Questions (FAQs)
Does this book cover a standard, simple ACL repair?
Only as a baseline. The entire purpose of this book is to address the complex rotatory forces that cause standard ACL repairs to fail.
Who is the primary audience?
It is the absolute, mandatory surgical atlas for Orthopedic Sports Medicine Surgeons, Knee Specialists, and advanced Athletic Trainers.
