Diagnosis of Knee Joint Osteoarthritis using Synovial Fluid Density Measurement based Bioelectrical Impedance
Main Article Content
Abstract
According to the World Health Organization (WHO), arthritis is the biggest cause of disability worldwide. It is also one of the most common inflammatory conditions affecting the musculoskeletal system. Synovial fluid is often present in the joint area and serves as a lubricant, which is an essential function. The fluctuation in density of synovial fluid may be used to detect arthritis. This might be done to assess the severity of the disease. This work provides a non-invasive approach for measuring changes in synovial fluid density based on the electrical bio-impedance idea. The purpose of this study approach is to measure change. The current research studied the parameters estimated by bioelectric impedance spectroscopy (BIS) in persons with healthy knees and knees with osteoarthritis (OA). A comparison was done between the two groups of people. Because tissue may be represented as both resistance and capacitive reactance, bio-impedance values are calculated using the voltage drop in relation to the joint tissue area. When the frequency and voltage are held constant, the resistance and reactance values change from a healthy individual to a patient with arthritis. This happens even when everything else stays the same.
