Clinical value of questionnaires & physical tests for patellofemoral pain: Validity, reliability and predictive capacity

Objectives To determine the most appropriate method of functional assessment for "patellofemoral pain" (PFP)/“chondromalacia patella” for its diagnostic value, (validity, reliability, sensitivity, specificity, predictive value and clinical applicability); to outline initial interpretations of the questionnaires and their appropriateness, through the cut-off points determined in their scores based on physical test and Magnetic Resonance Imaging (MRI); to establish which methods should be used in conjunction with each other to obtain clinical diagnoses that are robust effective and efficient. Methods (1)Intra- and inter-observer reliability and of the relationship among PFP questionnaires/physical tests validated. (2)Predictive capacity of the questionnaires. Subject: 113 knees with PFP, assessed using “Knee-injury-and-Osteoarthritis Outcome-Score-for-Patellofemoral-pain-and-osteoarthritis” (KOOS-PF), “Kujala-Patellofemoral-Score” (KPS), “Victorian-Institute-of-Sports-Assessment-for-Patellar-tendons-questionnaire” (VISA-P), and the physical tests: “patellar-palpation”, “patellar-tilt”, “patellar-apprehension”, “Clarke” and “squat”.
