[Objective]To investigate the risk factors of anterior cruciate ligament injury(ACLI)caused by vault training and the effect of postoperative rehabilitation training.[Methods]A retrospective study was done on the patients who underwent arthroscopic ACL recon-struction for ACLI due to vault training in The 940th Hospital,Joint Logistics Support Force of PLA from October 1,2019 to October 31,2022.The data regarding their general information,injury status,follow-up and re-training data were compared.[Results]A total of 356 patients with knee joint injury caused by vault training were included into this study,including 117 patients with knee joint injury caused by vault training I,158 patients with knee joint injury caused by vault training Ⅱ and 81 patients with knee joint injury caused by vault training Ⅲ.The VAS score,Lysholm score and ROM were significantly improved in the patients after operation compared with those preop-eratively(P＜0.05).However,there were no significant differences in the main evaluation parameters,including different age,different mili-tary ranks,different time periods after injury and different injury subjects(P＞0.05).During the follow-up,99(27.8％)of the 356 patients reached the standard of re-training,and it took an average of 16 months to recover to the state of re-training.[Conclusion]Vault training is an important cause of ACLI.Although the patients are well recovered in clinic state,the recovery period after injury is long and the re-train-ing rate is low.
