Application of the radiographic joint line distance (RJLD) measurement in revision knee arthroplasty, which is associated with significant bone loss. a The RJLD of the contralateral knee measured 48.18 mm on the scaled X-ray image. b During operation, an addition of a total of 16-mm thickness augmentation almost restored the planned joint line distance, as was shown by the intraoperative joint line distance measurement. c The RJLD (48.13 mm) measured on the postoperative radiograph confirmed the restoration of the joint line position in surgery
