INTRODUCTION Anterior cruciate ligament (ACL) rupture in skeletally immature athletes is becoming an injury with increasing incidence. Choices of treatment are still debated, including conservative management vs. various surgical techniques. The lack of long-term reports has been highlighted in the literature. AIM To evaluate long-term results of ACL reconstructions performed in skeletally immature patients using the Over the Top technique with lateral extra-articular tenodesis. METHODS Retrospective study. All surgeries performed by same surgeon. A total of 42 patients included. All patients had pre-operative radiological studies. SUBJECTS 30 males and 12 females. Average age: 12.5 years (range 11-14 years). Average follow-up: 96.1 months. Clinical evaluation: Pedi-IKDC, Tegner-Lysholm, KT-1000 and plain radiographs. Standardized rehabilitation protocol. RESULTS No instability or leg length discrepancy was recorded. Average pre-operative Tegner-Lysholm and Pedi-IKDC scores were 55 and 40, respectively, with a score of 94.8 (p < 0.05) and 94.78, respectively, at final follow-up (p < 0.05). Average post-operative (1 month) Tegner-Lysholm score: 75 (range: 62-79). Median post-operative Tegner activity: 8. Mean side-to-side (KT-1000): 1.2 mm. A total of 22 patients could go back to pre-injury sport activity, with an average rehabilitation of 7.3 months. DISCUSSION A significant number of cases were included in our structured standardized study and follow-up. Functional scores were excellent overall. Excellent results are testified by a final achievement of 22 patients going back to pre-injury sport activity, which is in keeping with the literature. Our experience exhibited a low complication rate and no metalwork failure. We correlate our results to the use of the Over the Top technique with lateral extra-articular tenodesis. CONCLUSION The studied procedure seems to be an excellent option and an effective, feasible and safe technique when treating ruptured ACLs in skeletally immature patients.

开放性植骨患者的前交叉韧带上方重建：一项长期随访研究。

简介骨骼未成熟运动员的前交叉韧带（ACL）破裂正成为一种伤害，发病率不断上升。治疗的选择仍在争论中，包括保守治疗与各种手术技术。文献中强调了缺乏长期报告。目的评估使用未成年人骨骼外伸术的Over Top技术对骨骼未成熟患者进行ACL重建的长期结果。方法回顾性研究。所有手术均由同一位外科医生执行。总共包括42例患者。所有患者术前均接受放射学检查。受试者30例男性和12例女性。平均年龄：12.5岁（范围11-14岁）。平均随访：96.1个月。临床评估：Pedi-IKDC，Tegner-Lysholm，KT-1000和X线平片。标准化的康复方案。结果未记录任何不稳定性或腿长差异。术前Tegner-Lysholm和Pedi-IKDC的平均评分分别为55分和40分，在最终随访时分别为94.8分（p <0.05）和94.78分（p <0.05）。术后平均（1个月）Tegner-Lysholm得分：75（范围：62-79）。术后Tegner活度中位数：8。平均左右（KT-1000）：1.2毫米。总共有22名患者可以恢复到受伤前的体育活动，平均康复时间为7.3个月。讨论我们的结构化标准化研究和随访中包括了大量病例。功能评分总体上很好。22名患者恢复到受伤前的运动活动的最终成就证明了其出色的结果，这与文献资料相符。我们的经验表明并发症发生率低，没有金属制品故障。我们将我们的结果与“外侧”技术与外侧关节外腱膜的使用相关联。结论研究的方法似乎是治疗骨骼不成熟患者破裂的ACL的绝佳选择，是一种有效，可行和安全的技术。
