What Is New in Knee Surgery?

The traditional orthopaedic principle of restoration of anatomy has experienced a renaissance within the field of extra-articular knee reconstruction in recent years. Knee surgeons have moved again toward more anatomical ligament restoration, while continuing to develop extra-articular augmentation procedures to protect these anatomical reconstructions. Interesting recent developments in the field of extra-articular knee reconstruction include advances in the anatomical management of patellofemoral instability, posterolateral corner injury, medial collateral ligament injury and paediatric anterior cruciate ligament injury, and in the understanding of allograft and platelet-rich plasma use. Extra-articular knee reconstruction has evolved to a state where surgeons have seen improved results when advances in biological and antomical understanding are applied to surgical techniques. This chapter outlines a number of the recent advances that have improved knee surgery outcomes.
