Determining the Relationship between Severity of Clinical Symptoms and Severity of Radiographic Findings in Patients with Knee Osteoarthritis
Keywords:Knee osteoarthritis, Clinical signs, Radiographic findings, Morning stiffness
Objective: This study was conducted to determine the relationship between severity of clinical symptoms
and severity of radiographic findings in patients with knee osteoarthritis.
Methods: In this cross-sectional analysis, 84 patients with knee osteoarthritis were studied. Clinical signs,
including pain, joint effusion, morning stiffness, and limb deformity, were compared with the Kellgren and
Lawrence radiographic classification reviewed by each patient.The relationship between K/L garde and
BMI, age, duration of disease and gender was also investigated.
Results: This study conducted on 84 patients with knee osteoarthritis found a significant direct relationship
betweenquantitative pain, VAS, and K/Lscore,as well asqualitative pain and K/L score(P=0.000).Moreover,
there was a significant relationship between morning stiffness duration and gender (P=0.012). A direct
relationship was also reported between disease duration and K/L score of patients (P=0.000) and Pearson
coefficient was positive.
Conclusion: this study proved that with increasing VAS and patients’ pain, patients are in a higher
classification of K/L score.
