Arthroscopic diagnosis was used to determine the incidence of the most frequent injuries to the knee's internal structures associated with ACL tear as well as ones without ACL tear. The most frequent finding associated with a recent ACL tear was the LM tear (72.7%). There is a statistically significant incidence of recent LM tear in knees with a recent ACL tear compared with recently injured knees without an ACL tear (P < 0.001). A statistically significant incidence of longitudinal LM tear was found in knees with a recent ACL tear compared with recently injured knees without an ACL tear (P < 0.001). Longitudinal tears were present in 63.6% of the knees with a recent ACL tear or in 87.5% of all knees with a recent LM tear. No statistically significant difference was found in the incidence of LM tear in the knees with a recent ACL tear compared to the incidence of LM tear in knees with an old ACL tear (P > 0.05). The posterior horn was most frequently injured (71.5% vs 64.0%). A significant difference between the findings in the various patient groups studied supports the hypothesis that longitudinal LM tears in an ACL-deficient knee do not involve secondary meniscal pathology but that their onset derives from a primary recent injury. Most probably, the recent LM lesion does not evolve in meniscal length and depth. This hypothesis needs thorough investigation.
关节镜诊断用于确定与前交叉韧带（ACL）撕裂相关以及无ACL撕裂的膝关节内部结构最常见损伤的发生率。与近期ACL撕裂相关的最常见发现是外侧半月板（LM）撕裂（72.7%）。与近期无ACL撕裂的受伤膝关节相比，近期有ACL撕裂的膝关节中近期LM撕裂的发生率具有统计学意义（P < 0.001）。与近期无ACL撕裂的受伤膝关节相比，近期有ACL撕裂的膝关节中纵向LM撕裂的发生率具有统计学意义（P < 0.001）。在近期有ACL撕裂的膝关节中，63.6%存在纵向撕裂，在近期有LM撕裂的所有膝关节中，87.5%存在纵向撕裂。与陈旧性ACL撕裂的膝关节中LM撕裂的发生率相比，近期有ACL撕裂的膝关节中LM撕裂的发生率无统计学意义（P > 0.05）。后角最常受伤（71.5%对64.0%）。所研究的不同患者组的发现之间的显著差异支持以下假设：ACL缺失膝关节中的纵向LM撕裂不涉及继发性半月板病变，但其发病源于近期的原发性损伤。很可能，近期的LM损伤在半月板长度和深度上不会发展。这一假设需要深入研究。
