Abstract: BACKGROUND: Most patients with anterior cruciate ligament fracture need surgical reconstruction of knee stability, but there are still controversies in the location of bone canal, graft selection and fixation method during reconstruction.  
OBJECTIVE: To investigate the safety and efficacy of double suspension titanium plate for anterior cruciate ligament reconstruction.
METHODS: The clinical data of 65 patients undergoing arthroscopic anterior cruciate ligament reconstruction with autogenous tendon from January 2019 to May 2021 were retrospectively analyzed. They were divided into two groups. In the double suspension group (n=30), only the semitendinosus tendon was obtained from the autologous tendon transplantation, and the anterior cruciate ligament was reconstructed by the whole-internal technique double-loop titanium plate suspension. In the conventional surgery group (n=35), the semitendinosus and gracilis tendons were obtained from autologous graft tendon, and fixed with tibial sheath and tibial absorbable conical screws. Operation duration, length and diameter of grafted tendon after braiding were compared between the two groups. Postoperative visual analogue scale score, knee stability (KT2000), knee function score: International Knee Documentation Committee score, Lysholm score, Tegner score; perioperative complications and other indicators were analyzed.  
RESULTS AND CONCLUSION: (1) There were no statistically significant differences in surgical duration, perioperative visual analogue scale score, knee function score and stability between the two groups (P > 0.05). (2) Graft length and diameter after tendon braiding were longer in the conventional surgery group than those in the double suspension group (P < 0.05). (3) These results suggested that reconstruction of anterior cruciate ligament by double-loop titanium plate suspension under arthroscopy can achieve the same function and stability of knee joint as that of the conventional surgery group, and the function of gracilis muscle and more tibial bone mass are retained in the double suspension group, which is safe and effective in clinical application.
