To evaluate whether clinical factors enable prediction of the diameter of hamstring tendons harvested for anterior cruciate ligament (ACL) reconstruction.
Eighty patients were submitted for reconstruction of the ACL with hamstring tendons in a quadruple manner. During surgery the diameter of the graft was measured. The variables analyzed were: age, gender, weight, height, operated side, dominant side, leg length, thigh length, thigh diameter, body mass index (BMI), and sports activity. The data was collected pre-operatively and correlated with the diameter of the graft.
The diameter of the graft was strongly related to gender, height, leg length, thigh length, weight, and thigh diameter. Women presented significantly smaller graft diameter than men; as well as weight, height, leg length, and thigh length. Men with height equal to or greater than 1.80 m showed average graft diameter greater than the total group, and greater percentage of 9 mm grafts.
The diameter of the hamstring graft is significantly associated to weight, height, leg length, thigh length, thigh diameter, and gender. The variable that had most influence was height, followed by gender and leg length. The variables BMI, age, sports activity, and dominant side did not present correlation. Tendon diameter was larger in men than in women. Men with a height equal to or greater than 1.80 m had a higher prevalence of 9 mm grafts and had a larger average tendon diameter.
Prospective cross sectional collection of data, Level IV.
评估临床因素是否能预测用于前交叉韧带（ACL）重建的腘绳肌腱的直径。
80 名患者接受了四股腘绳肌腱重建 ACL。在手术中测量了移植物的直径。分析的变量包括：年龄、性别、体重、身高、手术侧、优势侧、腿长、大腿长、大腿直径、体重指数（BMI）和运动活动。数据在术前收集，并与移植物的直径相关联。
移植物的直径与性别、身高、腿长、大腿长、体重和大腿直径密切相关。女性的移植物直径明显小于男性；体重、身高、腿长和大腿长也较小。身高等于或大于 1.80 米的男性的平均移植物直径大于总组，并且 9 毫米移植物的比例更高。
腘绳肌腱的直径与体重、身高、腿长、大腿长、大腿直径和性别显著相关。影响最大的变量是身高，其次是性别和腿长。BMI、年龄、运动活动和优势侧变量没有相关性。男性的肌腱直径大于女性。身高等于或大于 1.80 米的男性 9 毫米移植物的比例更高，平均肌腱直径更大。
前瞻性横断面数据收集，IV 级。
