OBJECTIVE
The purpose of this study was to evaluate the influence of patient age on the effects of conservative treatment of the anterior cruciate ligament (ACL).
METHODS
A total of 102 consecutive patients with acute ACL injury were allowed to heal without surgery. Final magnetic resonance imaging images of the ACL were classified from grade I, indicating good morphological recovery, to grade IV, indicating poor recovery. Chi-square analysis was used to determine significant differences in the incidence of grades I and II among those less than 20 versus those 20 years or more of age.
RESULTS
The mean follow-up to final magnetic resonance imaging was 9 months. A significant difference in the frequency of grades I and II was observed between age groups (<20 years, 13.0%; ≥20 years, 69.6%; P < 0.0001).
CONCLUSION
ACL injury was more severe, and morphological recovery with conservative treatment was poorer among younger patients than among adults.
目的
本研究旨在评估患者年龄对前交叉韧带（ACL）保守治疗效果的影响。
方法
共102例急性ACL损伤患者未经手术而接受自行愈合。ACL的最终磁共振成像图像分为I级（表示形态恢复良好）至IV级（表示恢复较差）。采用卡方分析确定年龄小于20岁与20岁及以上患者中I级和II级发生率的显著差异。
结果
至最终磁共振成像的平均随访时间为9个月。在不同年龄组之间观察到I级和II级频率存在显著差异（<20岁，13.0%；≥20岁，69.6%；P<0.0001）。
结论
年轻患者的ACL损伤比成人更严重，保守治疗后的形态恢复也比成人差。
