Reliability of measurements obtained with four tests for patellofemoral alignment.

Abstract

BACKGROUND AND PURPOSE: A series of patellofemoral (PF) alignment tests have been described that are used to determine when and how PF taping techniques should be applied. The reliability of measurements obtained with these tests has not been reported. The purpose of this study was to determine the intertester reliability of measurements obtained with four PF alignment tests: medial/lateral displacement, medial/lateral tilt, medial/lateral rotation, and anterior tilt. SUBJECTS: Twelve physical therapists from four clinics served as testers. A total of 66 patients were evaluated. METHODS: Paired testers performed all four PF alignment tests on the same patient. The intertester reliability of ..
