Perform a comparative study of non-weight bearing and weight bearing x-ray of both knees in classification of kellgren and Lawrence (KL). This study was done in 2024 from January to June where x-ray of 50 patients having non-weight bearing compared with weight bearing both knee x-ray were classified as per KL grading system of knee osteoarthritis. Out of 50 patients, 9 who were previously diagnosed with grade0 and No joint space narrowing were found to have grade1 osteoarthritis. Of the 13 patients initially diagnosed with grade1 osteoarthritis were reclassified as having grade2, 12 were reclassified as having grade2 to grade3 osteoarthritis, while 16 patients initially diagnosed with grade3 osteoarthritis were reclassified as having grade4 osteoarthritis. The study revealed that weight-bearing X-rays are a more effective diagnostic tool than non-weight-bearing X-rays, as they show a significantly reduced intra-articular gap, particularly on the medial side.
