Abstract

Purpose: The aim of the study was to investigate the relationship between pain, function and quality of life with radiographic findings in patients with knee osteoarthritis (OA).

Methods: A total of 86 patients diagnosed with knee OA were included in the study. Demographic, physical, and pathological information was collected. Visual analog scale (VAS) was used to determine pain levels. The evaluation of radiographic findings was conducted by Kellgren-Lawrence (K&L) rating scale. The Turkish version of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire was used to evaluate the patient's disability and functional status. The objective functional status was assessed using the commonly used physical performance test, the Timed up and Go Test (TUG). The Turkish version of the Short Form 36 (SF-36) questionnaire was used for quality of life assessment. The "Spearman rank correlation coefficient" was used to investigate the relationship between pain, function and quality of life with radiographic findings.

Results: The mean age of the participants was 61.08 ± 9.27 years. There was a strong correlation between VAS at activity and K&L (p < 0.05). There was a negative correlation between Physical Function (PF) (p < 0.05) and General Health (GH) (p < 0.05) subscore of the SF-36 with K&L. In addition, K&L and TUG were positively correlated (p < 0.05).

Conclusion: Radiographic findings were associated with pain in activity and functional status based on physical performance, but not with clinical results based on Patient Reported Outcome Measures (PROMs). As the patient's radiographic findings worsened, the level of pain increased and functionality decreased.
