Significant focus has recently been placed on the contribution of the anterolateral ligament (ALL) to controlling anterolateral rotatory laxity of the anterior cruciate ligament (ACL) injured knee. Many recent studies have investigated the use of magnetic resonance imaging and ultrasound on determining the degree of ALL injury and whether this is correlated to high-grade rotatory laxity. Unfortunately, most studies lack a reference standard, and as such it is challenging to determine whether it truly is the ALL that is injured or if the capsule-osseous layer and deep iliotibial band are involved...

From an orthopaedic perspective, our military personnel truly are warrior athletes. Distilling the information available in these subjects provides an enlightening microcosm of the management of femoroacetabular impingement (FAI). Symptoms associated with damage caused by FAI represent the culmination of a process present since childhood. Thus, while arthroscopic correction can result in significant improvement, it does not invariably result in full restoration of function. Numerous factors influence an individual's response to injury and recovery from surgery, including subjective parameters such as resiliency...
