Fig. 1From: Weight-bearing knee flexion angle better correlates with patient-reported outcome measures than non-weight-bearing condition in total knee arthroplasty: a three-dimensional analysis study(a) The non-weight-bearing (NWB) knee flexion angle was measured using a goniometer. (b) The NWB knee flexion angle was measured using a fluoroscopic three-dimensional (3D) analysis. (c) The weight-bearing (WB) knee flexion angle was measured using fluoroscopic 3D analysisBack to article page
