This issue of Clinics in Sports Medicine, Guest Edited by Alexander K. Meininger, MD, is devoted to Leg Pain in Athletes.? Leg pain is a common manifestation of many ailments for which the athlete is vulnerable. In this issue, authors will discuss the most common causes of leg pain, including tibial stress syndrome, stress fractures, and exertional compartment syndrome. Attention will also be given to the evaluation of the injured runner, risk factors (such as the female athlete triad), and useful imaging adjuncts will be discussed.

This issue of Clinics in Sports Medicine will focus on patellofemoral disorders and how they are among the most common clinical conditions managed in the orthopaedic and sports medicine setting. The correct diagnosis at an early stage is essential if subsequent treatment is to be successful and secondary complications are to be avoided. Nonoperative intervention is usually the first form of treatment; however, there is no consensus on the most effective method of treatment.
