Sports Medicine and Arthroscopy Review: March 2006 - Volume 14 - Issue 1 - p 44-50 Buy Abstract Chronic posterolateral rotatory instability of the knee was introduced as a diagnostic classification by Hughston and associates in the early 1970s and occurs as a result of dysfunctional healing of a strained arcuate complex, causing a patulous posterolateral capsuloligamentous complex to exist. This capsular redundancy allows varying degrees of recurvatum and adduction instability during single-limb stance. Eradication of the redundant pouch with a capsular shift-type reconstruction has been shown to eliminate the instability and hold up under long-term follow-up studies. Understanding the complex normal and injured anatomy of the posterolateral corner of the knee is essential for effective reconstruction of this instability. © 2006 Lippincott Williams & Wilkins, Inc.
