Abstract:
INTRODUCTION:Commonly used clinical tests for posterior cruciate ligament (PCL) rupture detection exhibit several limitations, thus requiring more precise clinical PCL tests. The lateral-anterior drawer (LAD) test has been proposed as a manually applied testing alternative but not yet been evaluated in vivo. METHODS AND ANALYSIS:Fifteen patients presenting with an MRI-confirmed acute or chronic unilateral PCL rupture and 15 subjects with no prior knee injury in their medical history will be included in this prospective single-blinded cross-sectional cohort study. Three examiners with different lengths of working experience (range 1-30 years), blinded to MRI outcomes and patient history, will use the LAD test on both knees of each participant to test for PCL integrity. Examiners will independently document the PCL status of each knee on a blank case report form. Fleiss-Kappa values will be calculated to investigate whether the LAD test shows clinically significant interrater and intrarater reliability. Furthermore, LAD test outcomes will be compared with MRI which serves as reference standard to check for concurrent validity. Moreover, LAD test accuracy with respect to tester experience will be evaluated. ETHICS AND DISSEMINATION:The study will be conducted in agreement with the World Medical Association Declaration of Helsinki (2013). Ethical permission (EK16-081-0616) to conduct this study was obtained from the review board of the city of Vienna on 1 September 2016. All personal and research data will be used in accordance with the Austrian Federal Data Protection Act and will be anonymised before publication in relevant international peer-reviewed journals. TRIAL REGISTRATIONNUMBER:DRKS00013268; Pre-results.
