Hubungan Derajat Nyeri dengan Derajat Kelainan Radiologi Pada Lutut Pasien Osteoarthritis di Rumah Sakit Pendidikan Prof. Dr. Chairuddin Panusunan Lubis Universitas Sumatera Utara

Abstract

Background: Knee osteoarthritis (OA) is a degenerative joint disease characterized by progressive damage to the articular cartilage resulting from an imbalance between the synthesis and degradation processes within the joint tissues, including the extracellular matrix, chondrocytes, and subchondral bone. This condition commonly occurs in older adults and is primarily associated with pain, with varying intensity levels among individuals. Objective: To determine the relationship between the degree of pain and the degree of radiological abnormalities in patients with knee osteoarthritis at Prof. Dr. Chairuddin P. Lubis Universitas Sumatera Utara Hospital, Universitas Sumatera Utara, Medan, 20155, INDONESIA. Methods: This study waan analytical observational research with a cross-sectional approach involving 110 samples obtained from secondary data of knee OA patients’ medical records from January 2023 to May 2025. The degree of pain was assessed using the Visual Analogue Scale (VAS), while the degree of radiological abnormality was evaluated using the Kellgren–Lawrence (KL) classification. Data were analyzed using the Chi-Square test with a significance level of p ≤ 0.05. Results: Of the 110 samples, most patients were female (83.6%) and aged between 61–70 years (44.5%). The majority experienced moderate pain (74.5%) and had moderate radiological abnormalities (56.4%). The Chi-Square test showed χ² = 6.481 with a p-value of 0.371, indicating no significant relationship between the degree of pain and the degree of radiological abnormality in knee osteoarthritis (p > 0.05). Conclusion: There is no significant relationship between the degree of pain measured using the Visual Analogue Scale (VAS) and the degree of radiological abnormality of knee osteoarthritis assessed using the Kellgren–Lawrence (KL) classification (p = 0.371).
