Abstract

In clinical settings, where arthrometers are mainly used by different clinicians, knowing the inter-rater reliability of the instrument is crucial in order for the results from different examiners to be accurately interpreted and limitations fully understood. The aim of this study was to evaluate the inter-rater reliability of the GNRB® knee arthrometer. Knee anterior laxity in both knees was tested in a group of young, uninjured subjects (N=27, 13 females) by two examiners. Knee anterior laxity was calculated at test forces of 134 N and 250 N with values presented for the unstandardised and standardised conditions (relative to patellar stabilisation force). The ICCs ranged from 0.220 to 0.424. The inter-rater reliability of the GNRB® knee arthrometer is low.
