Effectiveness of weight bearing x-ray of both knees in classification of osteoarthritis

Abstract

This article is about the comparison of non-weight bearing single leg x rays with weight bearing x-rays of both knees. A study was done in 2023 from April to October where x-rays of 30 patients having non-weight bearing single knee x-rays were compared with weight bearing both knee x-rays. X rays were classified as per clinical staging and Kellgren and Lawrence grading system of knee osteoarthritis. Out of 30 patient 3 patients with minimal joint space narrowing earlier, diagnosed as mild osteoarthritis. 12 patients with mild osteoarthritis earlier, diagnosed with moderate osteoarthritis and 15 patients with moderate osteoarthritis earlier, diagnosed with severe osteoarthritis. It was found that weight bearing X-ray is better diagnostic tool than non-weight bearing as intra articular gap especially on medially side is much lesser in weight bearing X-ray.
