Study on Knee Osteoarthritis How X-Ray Alignment Relates to Pain and Fear of Movement

What this Trial Is About

Knee osteoarthritis is a common joint disease that causes pain, stiffness, and limits daily activities, especially in older adults. This research aims to explore how changes in the alignment of the lower limb, measured as the anatomical axis on knee X-rays, relate to patients pain levels, functional abilities, quality of life, and fear of movement kinesiophobia. The study is observational and cross-sectional, focusing on adult patients diagnosed with knee osteoarthritis. Participants will be adults with knee osteoarthritis who have had a standard anteroposterior knee X-ray taken within the last six months. The study involves no experimental treatment but includes clinical evaluations using validated scales pain measured by the Visual Analog Scale VAS, functional status by the Western Ontario and McMaster Universities Osteoarthritis Index WOMAC, quality of life by the Short Form-36 SF-36, and kinesiophobia by the Tampa Scale for Kinesiophobia TSK. Radiographic measurements of the femoro-tibial angle and joint space width will be performed by two independent observers. During the single study visit, participants will complete questionnaires assessing pain, function, quality of life, and fear of movement. Their existing knee X-rays will be reviewed for alignment and joint space. The study will analyze how these radiographic findings relate to clinical symptoms and patient-reported outcomes. No treatment interventions are given, and the study will help to better understand the role of anatomical alignment in knee osteoarthritis management.
