We undertook a cross-sectional study to evaluate the pennation angle and muscle thickness of the vastus lateralis muscle in patients undergoing unilateral anterior cruciate ligament (ACL) reconstruction with bone-patellar tendon-bone autograft, and compared these values with the contralateral non-operated limb.
Twenty three consecutive athletic males who underwent ACL reconstruction using the central third of the patellar ligament were evaluated at 25.9±1.5 months. The International Knee Documentation Committee (IKDC) score was administered, and angles of pennation and muscle thickness were measured by ultrasonography.
There was no significant difference in the pennation angle of the operated leg comparing to the contralateral leg (12.5°±1.81° in the operated leg; 13.25°±2.40° after the test; p=0.117). Quadriceps thickness in the operated leg was significantly decreased in all subjects compared to the contralateral leg (28.4±5.3mm in the operated leg; 32.7±4.85 mm in the contralateral leg; p=0.007).
Two years after surgery, there is no difference in pennation angle of the vastus lateralis when compared to the contralateral side in patients undergoing unilateral ACL reconstruction with bone-patellar tendon-bone autograft. There is a significant difference in quadriceps muscle thickness, which was less in the operated side on the operated side in all patients. Further studies are required to study the influence of muscle architecture on clinical outcome after ACL reconstruction surgery, and whether there are differences associated with the use of different grafts.
Case-control study; level IV.
我们进行了一项横断面研究，以评估接受自体骨-髌腱-骨移植进行单侧前交叉韧带（ACL）重建的患者股外侧肌的羽状角和肌肉厚度，并将这些值与对侧未手术肢体进行比较。
对连续23例使用髌韧带中三分之一进行ACL重建的男性运动员在术后25.9±1.5个月进行评估。采用国际膝关节文献委员会（IKDC）评分，并通过超声测量羽状角和肌肉厚度。
患侧与对侧腿的羽状角无显著差异（患侧为12.5°±1.81°；测试后为13.25°±2.40°；p = 0.117）。与对侧腿相比，所有受试者患侧的股四头肌厚度均显著降低（患侧为28.4±5.3mm；对侧为32.7±4.85mm；p = 0.007）。
对于接受自体骨-髌腱-骨移植进行单侧ACL重建的患者，术后两年患侧股外侧肌的羽状角与对侧相比无差异。股四头肌厚度存在显著差异，所有患者患侧均较薄。需要进一步研究肌肉结构对ACL重建手术后临床结果的影响，以及使用不同移植物是否存在差异。
病例对照研究；IV级。
