title: Evaluation of the knee.
abstract: The knee is frequently injured and affected by a variety of diseases. A precise history of injury or onset of symptoms is essential. The joint is ideally examined as soon after injury as possible. Examination should include observation of swelling, palpation of bony prominences, determination of the presence of effusion, recording of range of motion and evaluation of joint stability. Although x-ray studies constitute an important part of overall assessment, they only augment and not supplant thorough physical examination. Aspiration of joint effusion should be performed for diagnostic purposes, or to relieve pain. Arthrocentesis is indicated when effusion of uncertain etiology is present.
