The length and cross-sectional area of human semitendinosus and gracilis tendons were measured in both single- and multi-strand configurations for the purpose of anterior cruciate ligament graft preparation. The average lengths of the semitendinosus and the gracilis tendons were 235 +/- 20 mm (mean +/- SD) and 200 +/- 17 mm, respectively. The cross-sectional area of a doubled semi-tendinosus tendon (two strands) was significantly less than that of a 10-mm-wide patellar tendon graft (P < 0.001). The cross-sectional area of the tripled semitendinosus tendon (three strands) and the 10-mm-wide patellar tendon were similar. Doubling of the combined semitendinosus and gracilis tendons (four strands) and tripling of this combination (six strands) resulted in a significantly greater cross-sectional area in comparison to the 10-mm-wide patellar tendon (P < 0.05, four strands; P < 0.001 six strands). This investigation demonstrates that anterior cruciate ligament grafts fashioned using multiple-strand combinations of the semitendinosus and gracilis tendons result in a cross-sectional area that is comparable to the bone-patellar tendon-bone graft. This is an important finding since cross-sectional area reflects the intra-articular volume of collagenous tissue. This information should be helpful to surgeons considering using the hamstring tendons as an anterior cruciate ligament graft.
为了准备前交叉韧带移植，对人半腱肌和股薄肌腱在单股和多股配置下的长度和横截面积进行了测量。半腱肌和股薄肌腱的平均长度分别为235±20毫米（平均值±标准差）和200±17毫米。双股半腱肌腱（两股）的横截面积明显小于10毫米宽的髌腱移植体（P<0.001）。三股半腱肌腱（三股）和10毫米宽的髌腱的横截面积相似。半腱肌和股薄肌联合肌腱双股（四股）以及该组合三股（六股）时，与10毫米宽的髌腱相比，横截面积显著更大（四股时P<0.05；六股时P<0.001）。本研究表明，使用半腱肌和股薄肌腱的多股组合制作的前交叉韧带移植体，其横截面积与骨-髌腱-骨移植体相当。这是一项重要发现，因为横截面积反映了关节内胶原组织的体积。该信息对于考虑使用腘绳肌腱作为前交叉韧带移植体的外科医生应有所帮助。
