Abstract Objective: To explore the application value of improved double lower limbs full-length standing X-ray photography, splicing technology in total knee arthroplasty. Methods: We used the image data collected by same focal distance, X-ray vision, the tube center and exposure conditions points three times, obtaining 180 pieces from 60 patients by digital X-ray equipment. Using Microsoft office Excel and PicPick software to synthesise over 60 pieces of digital double lower limbs standing X-ray film, and to analyze the stitching double lower limbs length X-ray film, including the sites, image clarity, film density to see whether they have obvious differences, to evaluate the quality of image distortion and the reason of the knee joint deformity of abnormal line measurement. Results: The success rate of double lower limbs image matching is up to 95%. Besides, after mosaics of images tissue density is the same, and the image is clear and coherent. Most importantly, it can accurately measure and analyze the cause of abnormal line in knee joint deformity. Conclusion: The improved double lower limbs full-length standing X-ray photography, splicing technology has certain application value in total knee arthroplasty, and is worthy of popularization and application in grassroots hospital.
