“Sports injuries” are injuries that happen when playing sports or exercising. The severity of these injuries can range from minor to very serious, with some injuries requiring surgery to fully heal. There are many reasons for these injuries, such as poor training practices, improper equipment, or may just be an accident. Injuries can also occur when a person is not in proper condition to play the sport. Youth athletes often begin their competitive sports careers as early as age seven, if not sooner. With so many youth programs in the United States, the opportunity for injury in children and adolescents is enormous. Sports injuries are one of the leading causes of emergency room visits for children and adolescents.

The authors of these sections have done an excellent job of including types of sports injuries that they see in their patients, and treat. In lieu of an Adult Reconstruction Section, we are including a Special Section, The Future of Arthroplasty, that we feel is relative to this issue and very informative. All of these articles are written by experienced surgeons in orthopedics, and we thank them for providing their wisdom.
