Abstract:
Objective To compare the distribution of femoral osseous tunnels between using the em-pirical and fluoroscopic methods during anatomical reconstruction surgery for anterior cruciate ligament(ACL)rupture.Methods Between July 2019 and June 2022,46 patients who underwent arthroscopic ACL single-bundle anatomical reconstruction in our department were enrolled,including 34 males and 12 females,with 27 left and 19 right affected knees and a mean age of 31.8±4.9 years.The initial positioning of the femoral tunnel was based on the operator's experience,and later adjusted using the fluoroscopy.A rectangular box was drawn on the lateral view of the femoral tunnel,and the position of the tunnel was determined according to the proportion of the center of the tunnel in the deep-shal-low and the high-low directions.Then,the distribution of the femoral tunnel position in each direction and the degree of good positioning were compared between the initial and fluoroscopic localizations.Re-sults In the initial localization,in the x-axis direction,7 were too left,29 were correct and 10 were too right,with the corresponding number being 4,36 and 6 using the fluoroscopic localization.More-over,in the y-axis direction,30 and 3 cases were too high or too lower,with 14 norms using em-pirical method,while the numbers were 19,0 and 27 using the fluoroscopic positioning.The femoral tunnel was well-positioned in 11 cases(24%)at the time of initial positioning,and in 25 cases(54%)after fluoroscopic positioning adjustment.Conclusion The use of intraoperative fluoroscopy helps to im-prove the dispersion of the femoral osseous tunnel position in ACL single-bundle anatomical reconstruc-tion surgery.
