Relationship between the Serum Cartilage Oligomeric Matrix Protein Concentration against Degree of Knee Osteoarthritis Pain in Elderly Patients at the Public Health Service Clinic

Abstract

This study aims to assess the relationship between the serum concentration of Cartilage Oligomeric Matrix Protein (COMP) and the degree of osteoarthritis pain in elderly patients. The study was conducted at a public health service clinic, Faculty of Medicine, Syarif Hidayatullah State Islamic University (UIN) Jakarta, Indonesia. The indexes used to assess patients with OA in the knee are the Western Ontario and Mcmaster University Osteoarthritis Index (WOMAC). Sampling using the cross-sectional technique as many as 146 respondents with elderly knee OA patients. First, a physical and radiological examination is performed to confirm the diagnosis of knee OA. Second, measuring the degree of pain WOMAC. Third, the measurement of the COMP serum concentration used the ELISA test. Based on the Spearman correlation test, it was found that there was a statistically significant relationship between the COMP serum concentration and the degree of knee OA pain with the WOMAC scale in the elderly (p = 0.012). From the results of the study, it is suggested that patients maintain effective health management. Elderly patients come to community health service clinics to carry out routine/periodic checks to reduce pain. The main reason is that there is no truly effective and consistent method to prevent and cure this disease, especially for patients with age-related risk factors, excessive joint load, and a history of joint injury. AO also has an impact on a person's psychosocial well-being. These findings contribute to the study of the risk of degenerative diseases and the use of biomarkers with a level of evidence that will be more valid in the future.
