Aim Compared with the traditional position, we tried to explore the application of improved position for lower limb DR radiograph in hip and knee arthroplasty. Method Retrospective analysis of the traditional and improved DR radiographs from 60 cases for hip and knee arthroplasty, by comparing the division angle, lower limb mechanical axis length, mechanical deviation between the lower limb mechanical axis and the center of the tibial plateau. Results (1) Preoperative data from twenty cases of improved and 15 cases of traditional lower limb DR radiographs showed the mechanical deviations between the lower limb mechanical axis and the center of the tibial plateau were 28.18, 4.71, 30.66, 11.92; postoperative data from fifty cases of improved and 33 cases of traditional DR radiographs showed the mechanical deviations between the lower limb mechanical axis and the center of the tibial plateau were 5.04, 11.03 (P < 0.05). (2) Improved position much more clearly showed the full length of the lower limb, compared with traditional position. (3) Values preoperative correction angle of 31 cases of improved and 19 cases of traditional position were 5.9°, 6.7° (P < 0.05). Conclusion DR radiographs of improved position can realistically show the pre- and post-operative status of hip and knee. The data of correction angle, lower limb mechanical axis length, mechanical deviations between the lower limb mechanical axis and the center of the tibial plateau can be more accurate. It is more convenient for the selection of operation procedure and for the assessment of surgery and rehabilitation.
