Analysis of radiographic findings of osteoarthritis (OA) of knee joint using kellgren-lawrence scores in osteoarthritis of knee patients

Abstract

Background: The aim of this study was to investigate the radiographic findings in patients with knee osteoarthritis (OA). Methods: The present study was conducted on 120 symptomatic knees fulfilling American College of Rheumatology criteria for OA were included in the study. Patients with trauma, inflammatory, and infective conditions of the knee and with a history of intra‑articular interventions and surgery were excluded. Demographic data, body mass index (BMI), visual analog scale (VAS) were obtained. Kellgren–Lawrence (K‑L) score was obtained on radiography. Results: A total of 120 consecutive symptomatic knees were examined. The participants with a mean age of 50.66 ± 7.28 years, mean duration of disease of 4.20 ± 4.16 months, mean BMI of 28.20 ± 5.40 kg/m2, and mean score of VAS scale of 6.30 ± 1.50. K‑L grading of 1, 2, 3, and 4 was reported in 25%, 33.33%, 29.16%, and 12.5% of the knees, respectively. The mean VAS score showed statistically significant correlation with KL grading (P < 0.05). Conclusion: Our study found that K‑L grading and few ultrasonographic criteria showed a significant positive correlation with pain scores, while few other ultrasonographic criteria did not. Both imaging modalities are complementary to each other, rather than one being superior to the other.
