METHODS: Twenty-eight subjects with knee pathology diagnosed by a physician and with self-reported activity limitations were tested on one occasion using both methods. With subjects in sitting, the goniometric method used a standard goniometer to quantify the angle of the tibial surface relative to the subject’s sagittal plane in degrees of range of motion; whereas the MHT referenced the tibial tubercle relative to the patella, as either producing external rotation (positive test) or not (negative test).

A four-way analysis of variance (ANOVA) was used to compare the affected and unaffected knees for the goniometric method. A Sign Test and a Chi Square test were used to examine the frequencies of positive and negative MHT scores.
