Abstract
Background: Knee osteoarthritis is a degenerative and inflammatory disease causing pain and worsening patients' quality of life. Various conservative treatment options exist, but a gap between scientific evidence and clinical practice is still present. The aim of this prospective multicenter observational study is to describe the real outpatient territorial management of patients with knee osteoarthritis and to analyze the correlation between the anthropometric and clinical characteristics of the population of patients suffering from symptomatic knee osteoarthritis who were screened in the national survey. Methods: The educational national project was divided into three modules: the first and the last through webinars; and the second held in daily practice. The participants had to register structured observations, which were then stored in a national database and analyzed in order to identify correlations. The subgroups were stratified by body composition, radiological severity of knee osteoarthritis, pain, and functional ability. Results: The project has been joined by 155 physicians, and 2.656 observations about real-world outpatients being treated for knee osteoarthritis in Italy were collected. Data relating to real-world pharmacological and rehabilitation therapies in correlation with body composition, the radiological severity of knee osteoarthritis, pain, and functional ability were reported. Conclusions: Currently, there are no standardized protocols using effective combinations of therapeutic exercises, physical agents, and medications to control the progression of knee osteoarthritis. This real-word national survey proved to be useful for describing the current state of the art of therapeutic management of knee osteoarthritis and for emphasizing the need to fill the gap between scientific evidence and clinical practice.
