背景资料：最近的文献将前交叉韧带（ACL）重建失败与收获的腘绳肌（HS）自体移植物直径较小相关。然而，这种方法可能是一种简化，因为移植物大小与自体ACL大小的关系通常不进行评估，过大的移植物可能会产生其自身的并发症。目的：评估体内数据，以确定常用的自体移植物是否可靠地恢复自体ACL大小。研究设计：描述性实验室研究。方法：收集并回顾性评价了46例使用HS自体移植物进行ACL重建的患者的胫骨插入面积和HS移植物直径的术中数据。还对每例患者进行了可能的髌腱（PT）和四头肌腱（QT）自体移植物的横截面积（CSA）的磁共振成像测量。结果：ACL胫骨止点面积平均为107.2 mm（2）（60.5-155.5 mm（2））。PT、HS和QT的平均CSA分别为33.2、55.3和71.4 mm（2）。当所有移植物被评估时，胫骨部位的插入面积重建百分比从16.2%到123.1%不等，股骨部位的插入面积重建百分比从25.5%到176.7%不等，每种移植物类型差异显著（P
Background: Recent literature correlated anterior cruciate ligament (ACL) reconstruction failure to smaller diameter of the harvested hamstring (HS) autograft. However, this approach may be a simplification, as relation of graft size to native ACL size is not typically assessed and oversized grafts may impart their own complications.Purpose: To evaluate in vivo data to determine if the commonly used autografts reliably restore native ACL size.Study Design: Descriptive laboratory study.Methods: Intraoperative data of the tibial insertion area and HS graft diameter were collected and retrospectively evaluated for 46 patients who underwent ACL reconstruction with HS autografts. Magnetic resonance imaging measurements of the cross-sectional area (CSA) of the possible patellar tendon (PT) and quadriceps tendon (QT) autografts were also done for each patient. The percentages of tibial insertion site area restored by the 3 possible grafts were then calculated and compared for each individual.Results: The mean ACL tibial insertion area was 107.2 mm(2) (60.5-155.5 mm(2)). The mean CSAs of PT, HS, and QT were 33.2, 55.3, and 71.4 mm(2), respectively. When all grafts were evaluated, the percentage reconstruction of the insertion area varied from 16.2% to 123.1% on the tibial site and from 25.5% to 176.7% on the femoral site, differing significantly for each graft type (P
