Meniscal tears are one of the most common injuries encountered by medical specialists and physical therapists especially amongst the sports population. The diagnosis is based on detailed history taking and physical examination. The McMurray test and the joint-line tenderness test are often used for the diagnosis. In 2005, another potentially useful clinical test for the detection of meniscal tears was introduced, namely the Thessaly test. The aim of this study was to assess the diagnostic accuracy of the Thessaly test alone or in combination with the McMurray test.
