目的：本研究的目的是阐明解剖双束前交叉韧带（ACL）重建中股骨和胫骨隧道角度。研究方法：对50例连续患者进行了前瞻性研究，这些患者通过腘绳肌腱移植物接受解剖双束ACL重建术治疗单侧膝关节的慢性ACL缺损。在该手术中，使用Endopolymerase（Smith & Nephew Endoscopy，Andover，MA）将2个腘绳肌腱移植物固定在股骨上，并使用2个斯台普斯固定在胫骨上。每例患者在术后1年进行放射学检查。结果：前后位视图中后外侧束的胫骨隧道角平均为40.7度，侧位视图中平均为35.4度。前内侧束的胫骨隧道角度在前后位视图中平均为15.6度，在侧位视图中平均为41.4度。后外侧束的股骨隧道角度在前后位视图中平均为44.0度，在侧位视图中平均为52.0度。前内侧束的股骨隧道角度在前后位视图中平均为18.0度，在侧位视图中平均为49.8度。结论：这些数据将有助于外科医生在解剖双束重建中评估隧道位置和术后标准化。证据等级：11级，基于具有普遍应用的参考金标准的连续患者制定诊断标准。
Purpose: The purpose of this study was to clarify femoral and tibial tunnel angles in anatomic double-bundle anterior cruciate ligament (ACL) reconstruction. Methods: A prospective study was performed in 50 consecutive patients who underwent anatomic double-bundle ACL reconstruction via hamstring tendon grafts for chronic ACL deficiency in the unilateral knee. For this procedure, 2 hamstring tendon grafts were secured with EndoButtons (Smith & Nephew Endoscopy, Andover, MA) on the femur and with 2 staples on the tibia. Each patient underwent radiologic examination I year after surgery. Results: The tibial tunnel angles of the posterolateral bundle averaged 40.7 degrees in the anteroposterior view and 35.4 degrees in the lateral view. The tibial tunnel angles of the anteromedial bundle averaged 15.6 degrees in the anteroposterior view and 41.4 degrees in the lateral view. The femoral tunnel angles of the posterolateral bundle averaged 44.0 degrees in the anteroposterior view and 52.0 degrees in the lateral view. The femoral tunnel angles of the anteromedial bundle averaged 18.0 degrees in the anteroposterior view and 49.8 degrees in the lateral view. Conclusions: The given data will be useful for surgeons to evaluate the tunnel positions and standardization postoperatively in anatomic double-bundle reconstruction. Level of Evidence: Level 11, development of diagnostic criteria on the basis of consecutive patients with universally applied reference gold standard.
