PURPOSE The purpose of this study was to determine the anterior cruciate ligament reconstruction (ACLR) failure rate in young patients utilizing the New Zealand (NZ) anterior cruciate ligament (ACL) Registry. The hypothesis was that the ACLR rupture rate would be lower for thicker hamstring graft and bone patellar tendon bone (BPB) grafts in comparison to the classic hamstring technique. The ACLR failure rate was assessed according to graft type and patients' sex. METHODS The NZ ACL registry was utilized to identify all patients aged 20 years or younger at the time of surgery who were skeletally mature and had a minimum 2-year follow-up. Graft ruptures, defined as an ACL revision, were identified according to graft type (traditional 4 strands hamstring semitendinosus and gracilis, 4 strands semitendinosus, 5-6 strands semitendinosus and gracilis, 7-8 strands semitendinosus and gracilis, bone-patella-bone graft). RESULTS Nine-hundred and ninety-two patients were included. At a mean follow-up of 38 months, 52 cases of graft rupture were recorded, (overall failure rate: 5.2%). The failure rate was not statistically influenced by the graft diameter. Patients with a thinner graft (< 8 mm-196 patients) had a similar failure rate (6%) to patients with a thicker graft (8 mm or more-485 patients) (6.2%). There was a lower failure rate in the BPB group (3.1%) versus all hamstrings group (6%) (ns). Finally, BPB in females had a lower failure rate than all hamstring constructs together (0% versus 5.1%; p = 0.023) CONCLUSION: In a young population traditional four-strand hamstring grafts, multiple strand configurations or BPB ACLR, whatever their size (> or < 8 mm), showed no significant difference in the failure rate in the NZ ACL registry. Female patients who had an ACL reconstruction with BPB graft had a significant lower failure rate than patients who had a hamstring graft. LEVEL OF EVIDENCE III.

在年轻患者的前十字韧带重建中，较厚的绳肌或graft骨肌腱移植物可降低移植失败率。

目的本研究的目的是利用新西兰（NZ）前交叉韧带（ACL）注册系统确定年轻患者的前交叉韧带重建（ACLR）失败率。假设是，与传统的绳肌腱术相比，较厚的string绳肌腱移植物和bone骨腱骨（BPB）植株的ACLR破裂率会更低。根据移植物类型和患者性别评估ACLR失败率。方法使用NZ ACL注册中心来识别所有在手术时年龄在20岁以下的年轻患者，这些患者骨骼成熟并且至少接受了2年的随访。根据移植物类型（传统的4股semi腱肌和gra肌，4股半腱肌，5-6股半腱和gra肌，7-8股半腱和ino肌，bone骨-骨移植。结果纳入了92例患者。平均随访38个月，记录了52例移植物破裂病例（总失败率：5.2％）。失败率不受移植物直径的统计影响。移植物较薄的患者（<8 mm-196位患者）的失败率（6％）与移植物较厚的患者（8 mm或更多485位患者）（6.2％）相似。与所有腿筋组（6％）（ns）相比，BPB组的失败率（3.1％）更低。最后，女性的BPB的失败率低于所有绳肌构建体（0％比5.1％; p = 0.023）结论：在年轻人群中，传统的四链four绳肌移植，多股构型或BPB ACLR，无论其大小如何（ > 或<8 mm），则NZ ACL注册中心的失败率没有显着差异。用BPB移植进行ACL重建的女性患者的失败率显着低于使用绳肌移植的患者。证据级别III。
