The indications for hip arthroscopy have been well established. The results among athletes appear to be favorable and, in fact, are somewhat better than those reported among a general population.

Intraarticular disorders in athletes may go unrecognized for a protracted period of time, most commonly being diagnosed as a strain. With an increasing awareness of these intraarticular problems and the intensity of services often available to athletes, joint injuries are now being diagnosed earlier. However, this emphasis for earlier diagnosis must be tempered. It is still likely that extraarticular in

juries vastly outnumber injuries within the joint, and thus one should avoid the temptation for an extensive intraarticular workup for every simple muscle strain. Also, it is unknown whether early diagnosis necessitates early intervention. There is much that is not understood regarding the natural history of some of these intraarticular disorders. Thus, while it is difficult to say that a labral lesion identified by MRI will heal, it is uncertain how many of these may become clinically quiescent and asymptomatic or whether some of the signal changes evident on imaging may be caused by remote trauma that had previously become silent.

Nonetheless, arthroscopy has defined various sources of intraarticular hip pathology. In many cases, operative arthroscopy may result in significant symptomatic improvement. For some, arthroscopy offers a distinct advantage over traditional open techniques, but for many, arthroscopy now offers a method of treatment where none existed before.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
