Abstract

Magnetic resonance imaging (MRI) was performed on 15 patients, an average of 2.5 years after arthroscopically assisted bone-tendon-bone (BTB) anterior cruciate ligament (ACL) reconstruction, to evaluate the patellar tendon donor site. Five patients who had arthroscopically assisted ACL reconstruction using the semitendinosus tendon as a graft also were scanned bilaterally and evaluated. The mean difference between the involved and uninvolved patellar tendon length was -0.2 mm for the BTB patients and -2.6 mm for the semitendinosus patients. The mean difference between patellar tendon width for the BTB patients was 1.1 mm and 1.9 mm for the semitendinosus patients. The mean difference between patellar tendon thickness was 0.4 mm for the BTB surgery group and 0.02 mm for the semitendinosus surgery group. None of the differences were statistically significant. Results indicate that harvesting the central one third of the patellar tendon does not significantly affect the length, width, or thickness of the tendon at least 22 months after arthroscopically assisted BTB-ACL.

摘要

对15例患者进行了磁共振成像(MRI)检查,这些患者在关节镜辅助下进行骨-肌腱-骨(BTB)前交叉韧带(ACL)重建术后平均2.5年,以评估髌腱供区情况。对5例使用半腱肌肌腱作为移植物进行关节镜辅助ACL重建的患者也进行了双侧扫描和评估。BTB组患者患侧与未患侧髌腱长度的平均差异为-0.2毫米,半腱肌组患者为-2.6毫米。BTB组患者髌腱宽度的平均差异为1.1毫米,半腱肌组患者为1.9毫米。BTB手术组髌腱厚度的平均差异为0.4毫米,半腱肌手术组为0.02毫米。这些差异均无统计学意义。结果表明,在关节镜辅助BTB-ACL术后至少22个月,取髌腱中央三分之一对肌腱的长度、宽度或厚度没有显著影响。
