摘要
目的探讨关节镜下经前内侧入路(anteromedial,AM)建立股骨隧道的膝关节前交叉韧带(anterior cruciateligament,ACL)移植重建手术的改良方法的安全性。方法 2010年1～10月采用改良AM方法完成ACL重建20例(实验组),2009年1～12月采用传统AM方法完成ACL重建20例(对照组),比较2组股骨隧道的长度,股骨隧道斜度,股骨外髁后壁爆裂和后外侧管神经损伤的情况。结果实验组术中股骨隧道长度为(41.8±4.1)mm,显著长于对照组(37.2±4.4)mm(t=3.421,P=0.002)。实验组股骨隧道冠状角度为51.9°±7.7°,显著大于对照组39.1°±5.8°(t=5.938,P=0.000)。对照组1例出现股骨隧道后壁爆裂,2组其余患者未发现后壁爆裂和后外侧血管神经损伤。结论改良AM方法可以增加ACL重建手术的安全性。
Objective To investigate the safety of modified reconstruction of anatomic anterior cruciate ligament （ACL） by using anteromediai （AM） portal drilling technique. Methods During the period between January 2010 and October 2010, 20 patients who underwent ACL reconstruction with modified AM technique was set as the experimental group, and another 20 patients who recieved traditional AM technique between January 2009 and December 2009 was made as a control. The femoral tunnel length, blow- out along the back wall of the lateral femoral condyle, the coronal angle of the femoral tunnel and peroneal nervevascular structures injuries of the two groups were recorded and the assessments were analyzed statistically. Results The femoral tunnel length of the modified AM technique group was （41. 8 ± 4. 1 ） （32 -50） mm, which was significantly longer than that in the traditional AM technique group [ （37.2 ± 4.4） （29 -45） mm, t = 3. 421, P = 0. 002]. Moreover, the coronal angle of femoral tunnel in the modified technique group was 51.9°±7.7 °（35.0 °±61. 1 °） , which was significantly larger than that in the traditional technique group [ 39.1 °± 5.8 ° （ 30.2 °± 52.1 ° ） , t = 5. 938, P = 0. 000 ]. Back wall blowout was observed in one patient in the control group, and no peroneal nervevascular structures injuries was found in either of the groups. Conclusion Modified AM technique can increase the safety of the procedures of anatomic ACL reconstruction.
