Imaging used for the evaluation of knee pain has historically included weight-bearing anteroposterior (AP), lateral, and sunrise radiographs. We wished to evaluate utility adding (WB) posteroanterior (PA) view in flexion. hypothesize that (1) WB tunnel can detect radiographic osteoarthritis (OA) not visualized on AP, (2) combination AP increases detection OA, (3) this may provide additional information clinician evaluating pain. retrospectively reviewed radiographs 100 knees (74 patients) presenting with analyzed evidence arthritis. The significantly increased joint space narrowing lateral (p < 0.001) medial = 0.006) compartments over alone. combined views improved identification subchondral cysts 0.022), sclerosis tibial plateau 0.041), moderate-to-large osteophytes compartment 0.012), intercondylar notch 0.001), spine 0.001). is an effective tool affected painful knee, provided by image
