Abstract

The localization of pain made by a valid and reliable instrument to perform differential diagnosis of knee osteoarthritis (OA) and guide decision making. Objectives: To describe the location of pain in patients with knee OA and to verify which variables interfere with the presence of symptomatology. Methodology: A cross-sectional study evaluated 122 individuals with symptomatic knee OA. The instruments used were: assessment form, Numeric Pain Rating Scale (NPRS) adapted PKPM, 30-s chair-stand test (CST), Timed Up and Go (TUG) test, Lequesne Index and the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire. For statistical analysis, mean and standard deviation, frequency and percentage, Kolmogorov-Smirnov test, chi-square chi-square test and Classification and Regression Tree (CART). Data were analyzed using the statistical software SPSS, version 18.0 for Windows (Statistical Package for the Social Sciences Inc., Chicago, IL, USA). Results: Individuals assessed with symptomatic knee OA are more likely to have patellar pain (site 6) and less chance of quadricipital tendon, tibia, superior lateral site, patellar tendon and superior medial (site 5, 8, 2 and 7). The variable predictor of patellar pain was KOOS activities of daily life (ADL). Conclusions: The ADL are the variable that most interferes with the presence of patellar pain. Secondarily, we can consider age, TUG, Sports and Leisure Activity and TSL.
