Abstract: BACKGROUND: After an anterior cruciate ligament rupture, the proprioception of the knee joint will be damaged,  which thereby impacts the stability of the knee joint. Reconstruction of the anterior cruciate ligament through surgery is the current main treatment method; however, the recovery of proprioception of patients undergoing different reconstruction surgeries is different after different reconstruction methods.
OBJECTIVE: To investigate the recovery of proprioceptive function of the knee joint after the single-bundle anatomical reconstruction of the anterior cruciate ligament with residual stump under arthroscope.
METHODS: Seventy patients with anterior cruciate ligament rupture who were admitted at the Department of Sports Medicine, the First Affiliated Hospital of Kunming Medical University  from January 2015 to December 2018 and met the selection criteria were enrolled and randomly divided into two groups. In the experimental group, the anterior cruciate ligament was reconstructed through a single-bundle anatomy with residual stump, while in the control group the anterior cruciate ligament was reconstructed through a single-bundle anatomy without residual stump. After operation, the Lysholm score, International Knee Documentation Committee score, and threshold to detection of passive motion were used to evaluate the knee joint function and proprioception recovery of the patients. All enrolled patients signed the relevant informed consent forms, and the trial protocol was approved by the Ethics Committee of the First Affiliated Hospital of Kunming Medical University.
RESULTS AND CONCLUSION: At 3 and 6 months after operation, the Lysholm score and International Knee Documentation Committee score in the experimental group were significantly higher than those in the control group, and the threshold to detection of passive motion was significantly lower than that in the control group (P < 0.05). There was no significant difference in these scores between the two groups at 12 months after operation (P > 0.05). To conclude,  single-bundle anatomical reconstruction of the anterior cruciate ligament with residual stump is beneficial to the early recovery of proprioception and stability of the knee joint. 

Key words: anterior cruciate ligament, proprioception, single-bundle anatomical reconstruction with residual stump, follow-up, threshold to detection of passive motion
