BACKGROUND The incidence of anterior cruciate ligament (ACL) injury in the adolescent population is increasing. The quadriceps tendon-patellar bone autograft (QPA) has been established as a reliable graft choice for ACL reconstruction in the adult population. PURPOSE To investigate graft failure, ability to return to sport, patient-reported functional outcomes, joint laxity, and subsequent injury among adolescent patients >2 years after primary ACL reconstruction with the QPA. STUDY DESIGN Case series; Level of evidence, 4. METHODS Consecutive patients who underwent QPA ACL reconstruction performed by a single surgeon were identified from an existing database. Information available in the database included demographics, concomitant/subsequent injuries, surgical procedures, graft failure, return to sport, and Lachman examination collected by medical record review. Pediatric International Knee Documentation Committee (Pedi-IKDC) and Lysholm scores were collected by telephone or during a clinic visit >2 years postoperatively. RESULTS The final cohort included 81 of 104 consecutive adolescent patients aged 10 to 18 years (mean ± SD, 15.9 ± 1.7 years at the time of surgery) for whom follow-up information was collected at >2 years after surgery. The cumulative incidence of graft failure within the 36-month follow-up period was 1.2% (95% CI, 0.1%-11.4%). The rate of ipsilateral non-ACL injuries was similar (1.2%; 95% CI, 0.2%-7.6%). Contralateral ACL and non-ACL injuries requiring surgical intervention were documented in 9.8% (95% CI, 4.9%-19.5%). The median Pedi-IKDC score was 94 (interquartile range, 89-98). The median Lysholm score was 99.5 (interquartile range, 89.0-100.0). At 36 months after surgery, 87.9% (95% CI, 81.4%-94.9%) of individuals had returned to play. CONCLUSION The quadriceps tendon-patellar autograft is a novel graft that demonstrates excellent stability and favorable patient-reported outcomes. Based on these results, the QPA is a reliable choice for primary ACL reconstruction in adolescent patients.

在最少随访2年的青春期患者中，股四头肌肌腱合并Block骨前交叉韧带重建术的结果。

背景技术在青少年人群中，前十字韧带（ACL）损伤的发生率正在增加。股四头肌腱-auto骨自体移植（QPA）已被确定为成年人口ACL重建的可靠移植选择。目的研究在QPA初次ACL重建后> 2年的青春期患者中，移植物衰竭，恢复运动的能力，患者报告的功能结局，关节松弛以及随后的损伤。研究设计案例系列；证据级别，第4级。方法从现有数据库中识别出由单名外科医生进行QPA ACL重建的连续患者。数据库中可用的信息包括人口统计资料，伴随/随后的伤害，外科手术，移植失败，恢复运动，并通过病历审查收集Lachman检查。儿科国际膝关节文献委员会（Pedi-IKDC）和Lysholm评分是通过电话或术后2年以上的临床就诊收集的。结果最后的队列研究包括104名年龄在10至18岁（平均±SD，手术时为15.9±1.7岁）的104名连续青春期患者，他们在手术后> 2年收集了随访信息。在36个月的随访期内，移植失败的累积发生率为1.2％（95％CI，0.1％-11.4％）。同侧非ACL损伤的发生率相似（1.2％； 95％CI，0.2％-7.6％）。有9.8％记录了需要手术干预的对侧ACL和非ACL损伤（95％CI，4.9％-19.5％）。Pedi-IKDC评分中位数为94（四分位间距为89-98）。Lysholm评分的中位数是99。5（四分位数范围，89.0-100.0）。术后36个月，有87.9％（95％CI，81.4％-94.9％）的人恢复了比赛。结论股四头肌腱-auto骨自体移植是一种新颖的移植物，具有出色的稳定性和患者报告的良好结局。基于这些结果，QPA是青少年患者原发性ACL重建的可靠选择。
