手持超声用于个体化全软组织股四头肌腱前交叉韧带重建
简介
本研究介绍了一种利用手持超声设备个性化测量股四头肌腱形态的新方法，用于全软组织股四头肌腱自体移植物前交叉韧带（ACL）重建。传统上，推荐取长65-70mm、宽10mm的移植物以确保15-20mm的骨道内愈合，但股四头肌腱长度与身高相关：约80%成年女性和18%成年男性身高不足5英尺6英寸（约168cm），其肌腱长度可能不足以安全获取70mm移植物，易损伤肌肉…
英文摘要
BACKGROUND: The use of quadriceps tendon autograft for anterior cruciate ligament (ACL) reconstruction (ACLR) has substantially increased in popularity. Advantages include similar clinical outcomes to other autografts and greater intra-articular tendon volume. However, injury to the quadriceps muscle during graft harvest may compromise quadriceps recovery, which reduces clinical outcomes. Females have been identified as being at higher risk of poor quadriceps recovery after all soft tissue quadriceps tendon ACLR, with 61% of females reported to be unable to achieve terminal extension 6 weeks after surgery. INDICATIONS: To allow for 15 to 20 mm of graft-to-bone tunnel healing, autografts 65 to 70 mm long and 10 mm wide have been recommended for adults. A 3-dimensional magnetic resonance imaging study showed that quadriceps tendon length correlates with height and that 90% of patients 5'6" or taller had a quadriceps tendon length >70 mm. However, the Centers for Disease Control and Prevention (CDC) data show that 80% of adult females and 18% of adult males are shorter than 5'6" tall. This means that, for about half of adults and the vast majority of females, the quadriceps tendon may not support the harvest of a 70 mm all-soft-tissue graft without potentially injuring muscle tissue. TECHNIQUE DESCRIPTION: Quadriceps tendon length and morphology can be readily assessed by ultrasound. This video demonstrates an easy new method for measuring quadriceps tendon morphology using handheld ultrasound devices that takes <1 minute. RESULTS: This information provides surgeons with knowledge and tools to customize graft harvest to avoid quadriceps muscle injury. DISCUSSION/CONCLUSION: Avoiding the removal of the quadriceps muscle during graft harvest reduces the role that donor-site morbidity can play in compromising quadriceps recovery after ACLR.
