Only MR can safely exclude patients from arthroscopy.

Objective: The aim of this study was to determine in patients with subacute knee complaints and normal standardized physical examination the fraction of magnetic resonance imaging (MRI) studies showing arthroscopically treatable intra-articular pathology.

Material And Methods: There were 290 consecutive patients (between 16 and 45 years) with at least 4 weeks of knee complaints and low clinical suspicion of intra-articular pathology based on physical exam. Two hundred seventy-four patients were included.

Are radiographs needed when MR imaging is performed for non-acute knee symptoms in patients younger than 45 years of age?

Objective: The objective was to determine the value of radiographs in young adults with non-acute knee symptoms who are scheduled for magnetic resonance imaging (MRI).

Materials And Methods: Nine hundred and sixty-one consecutive patients aged between 16 and 45 years with knee symptoms of at least 4 weeks' duration were prospectively included in three participating hospitals. After applying exclusion criteria, 798 patients remained.

MR imaging: effectiveness and costs at triage of patients with nonacute knee symptoms.

Purpose: To prospectively evaluate the cost and effectiveness of magnetic resonance (MR) imaging performed to exclude the need for arthroscopy in patients with nonacute knee symptoms who are highly suspected clinically of having intraarticular knee abnormality.

Materials And Methods: The study was approved by the institutional review boards of three hospitals; informed patient consent was obtained. All 584 included patients (406 male, 178 female; mean age, 31.

Objectives: To evaluate the efficiency of the anterior approach for displaced supracondylar pediatric humeral fractures.

Design: A retrospective analysis.

Setting: Clinical and outpatient clinic care.
