Comparative analysis of knee radiographs between weight bearing AP and Rosenberg PA flexion view for knee osteoarthrosis

Abstract

: Osteoarthritis of the knee is highly prevalent in our country and a significant cause of morbidity. An early diagnosis is of paramount importance to provide treatment and delay it’s progression.: To evaluate the role of Rosenberg PA flexion view for early diagnosis of osteoarthritis, the degree of articular degeneration and the advantages of these views using Kellgren-Lawrence classification (KL), Ahlback grading (AB) and International Knee Documentation Committee (IKDC). Rosenberg PA flexion view significantly increased the detection of medial and lateral joint space narrowing (p<0.001) as compared to the standard weight bearing AP view alone. The severity of KL, Ahlback & IKDC scores increased significantly on Rosenberg view. The Rosenberg view increases the sensitivity of detection of JSN & the knee scores significantly & is an important tool for early diagnosis of OA.
