However, in recent years, thanks to studies conducted on the disease, it has been confirmed that the process which takes place and which triggers the disease is highly active, due to the imbalance between joint tissue destruction and repair.<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a></p><p id="par0010" class="elsevierStylePara elsevierViewall">OA is also considered to be a disease of the whole diarthrodial joint which is currently defined as an organ (the combination of specialized tissues which possess a certain structure and organisation for meeting with a specific function).<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">3</span></a> The trigger for the disease is usually damage brought about by one of the components involved (joint cartilage, synovial membrane, bone tissues, intra and periarticular soft tissues), which leads to joint failure. Furthermore, it is characterised by the progressive degradation and loss of the hyaline cartilage and subchondral bone, in addition to damage which occurs in the synovial tissues, associated with a thickening and sclerosis of the subchondral film, the formation of osteophytes, the distention of the joint capsule and changes to the periarticular soft tissues.<a class="elsevierStyleCrossRef" href="#bib0020"><span class="elsevierStyleSup">4</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">All of these conceptual changes are possible, due to the continuous study in the field of medicine and more specifically in that of rheumatic diseases.

To do so, the creation and follow-up of patient cohorts may be of significant contribution.</p><p id="par0020" class="elsevierStylePara elsevierViewall">Against this backdrop, for further study of this disease, in the year 2006 we initiated the creation and follow-up of a cohort of patients diagnosed with OA, called PROCOAC (PROspective COhort of A Coruña) in our centre. This enabled us to carry out incidence and progression studies that are associated with different OA phenotypes.

This project started with the study of a group of patients who attended the Emergency Services of our hospital due to abdominal pain and who had an X-ray of the abdomen where we were able to assess both hips in our population. With that information we also studied the presence of hip osteoarthritis. Thus, the inclusion criteria of the population making up the cohort were: a) patients over 55 who attended the Emergency Services of our hospital and those who had undergone a plain X-ray of the abdomen (including both hips, which allowed us to detect the presence or absence of osteoarthritis); b) patients who attended our Rheumatology Service with pain in their hands and with a radiographic diagnosis of OA in keeping with the American College of Rheumatology (ACR)<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">5</span></a> criteria; c) patients with knee pain and with a radiographic OA diagnosis of the knee in keeping with the ACR<a class="elsevierStyleCrossRef" href="#bib0030"><span class="elsevierStyleSup">6</span></a> criteria and patients with hip pain and diagnosed radiographically with OA of the hip, also in keeping with ACR<a class="elsevierStyleCrossRef" href="#bib0035"><span class="elsevierStyleSup">7</span></a> criteria.</p><p id="par0030" class="elsevierStylePara elsevierViewall">This inclusion process began in the year 2006 and remains active to date. All patients signed an informed consent form approved by the local ethics committee. After this, data were collected (review of medical record and interview with the patient) to complete the medical history (demographic and clinical information), biological samples (general analysis and genetic studies) and X-rays of both hands, knees and hips were taken.</p><p id="par0035" class="elsevierStylePara elsevierViewall">The recorded variables included a complete medical history (personal and family background), review of comorbidities (psoriasis, high blood pressure, diabetes, dyslipidaemia), a physical examination (anthropometry and joint examination).

One is that it only represents patients in a hospital environment and comparison with healthy patients (very low number) is limited. Furthermore, there were few patients who sought medical attention for OA of the hip as a reason for primary care, since they usually consulted this event in another specialty, such as the trauma unit. We cannot therefore state with these data that our cohort is representative of OA in Spain, because cohort creation and design was mainly directed at the study and advance of this disease regarding the concept of the different phenotypes and therapeutic attitudes based on them.</p></span><span id="sec0045" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0105">Conflict of interests</span><p id="par0165" class="elsevierStylePara elsevierViewall">The authors have no conflict of interests to declare.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:10 [ 0 => array:3 [ "identificador" => "xres1666363" "titulo" => "Abstract" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "abst0005" "titulo" => "Introduction and objective" ] 1 => array:2 [ "identificador" => "abst0010" "titulo" => "Methods" ] 2 => array:2 [ "identificador" => "abst0015" "titulo" => "Results" ] 3 => array:2 [ "identificador" => "abst0020" "titulo" => "Conclusions" ] ] ] 1 => array:2 [ "identificador" => "xpalclavsec1480655" "titulo" => "Keywords" ] 2 => array:3 [ "identificador" => "xres1666364" "titulo" => "Resumen" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "abst0025" "titulo" => "Introducción y objetivo" ] 1 => array:2 [ "identificador" => "abst0030" "titulo" => "Material y métodos" ] 2 => array:2 [ "identificador" => "abst0035" "titulo" => "Resultados" ] 3 => array:2 [ "identificador" => "abst0040" "titulo" => "Conclusión" ] ] ] 3 => array:2 [ "identificador" => "xpalclavsec1480654" "titulo" => "Palabras clave" ] 4 => array:2 [ "identificador" => "sec0005" "titulo" => "Introduction" ] 5 => array:3 [ "identificador" => "sec0010" "titulo" => "Material and methods" "secciones" => array:2 [ 0 => array:2 [ "identificador" => "sec0015" "titulo" => "Patients (PROCOAC cohort)" ] 1 => array:2 [ "identificador" => "sec0020" "titulo" => "Statistical analysis" ] ] ] 6 => array:3 [ "identificador" => "sec0025" "titulo" => "Results" "secciones" => array:2 [ 0 => array:2 [ "identificador" => "sec0030" "titulo" => "Cohort description" ] 1 => array:2 [ "identificador" => "sec0035" "titulo" => "Polyarticular osteoarthritis" ] ] ] 7 => array:2 [ "identificador" => "sec0040" "titulo" => "Discussion" ] 8 => array:2 [ "identificador" => "sec0045" "titulo" => "Conflict of interests" ] 9 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2020-04-08" "fechaAceptado" => "2020-08-08" "PalabrasClave" => array:2 [ "en" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Keywords" "identificador" => "xpalclavsec1480655" "palabras" => array:3 [ 0 => "Osteoarthritis" 1 => "PROCOAC" 2 => "Cohort" ] ] ] "es" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Palabras clave" "identificador" => "xpalclavsec1480654" "palabras" => array:3 [ 0 => "Osteoartritis" 1 => "PROCOAC" 2 => "Cohorte" ] ] ] ] "tieneResumen" => true "resumen" => array:2 [ "en" => array:3 [ "titulo" => "Abstract" "resumen" => "<span id="abst0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0010">Introduction and objective</span><p id="spar0060" class="elsevierStyleSimplePara elsevierViewall">The use of well characterized osteoarthritis (OA) cohorts is mandatory for the study and knowledge of this disease.
