BACKGROUND: It is very important to evaluate intraarticular knee pathologies carefully to make a proper diagnosis. The most important diagnostic tools are history-taking, physical examination including special knee tests, and radiology including magnetic resonance imaging. The purpose of this study is to make a comparison between physical examination and magnetic resonance imaging for intraarticular knee pathologies before knee arthroscopy which is accepted as the gold standard for these types of pathologies.
METHODS: Knee arthroscopy was performed for 968 knees of 918 patients. Physical examination, magnetic resonance imaging and arthroscopic findings were evaluated and compared. Arthroscopy was accepted as the gold standard diagnostic technique. Sensitivity, specificity, and accuracy rates of physical examination and magnetic resonance imaging were compared.
RESULTS: Comparisons were made for medial meniscus, lateral meniscus, anterior cruciate ligament and cartilage lesions. The sensitivity and specificity of physical examination and magnetic resonance imaging were found high for medial meniscus lesions and anterior cruciate ligament lesions. Sensitivity and specificity were found similar between the two groups for these four types of intraarticular knee pathologies. No statistical difference was found.
CONCLUSIONS: Intraarticular knee pathologies such as medial meniscus, lateral meniscus, anterior cruciate ligament and cartilage lesions can be detected similarly by physical examination and magnetic resonance imaging. A careful physical examination is very important to detect intraarticular knee pathologies before magnetic resonance imaging.
