使用人体测量学参数预测前交叉韧带重建中四股腘绳肌腱移植物厚度：一项前瞻性研究
简介
一项前瞻性研究纳入48例行腘绳肌腱自体移植物ACL重建的患者，测量术前身高、体重、BMI及大腿围等人体测量参数，并与术中移植物直径进行相关性分析。结果显示身高与移植物直径呈强正相关（r=0.666），大腿围呈中度正相关，BMI呈负相关，男性移植物直径显著大于女性。术前根据人体测量参数可预测移植物直径，有助于识别移植物偏细的高危患者并指导术前移植物方案规划，但…
英文摘要
BACKGROUND: Anterior cruciate ligament (ACL) reconstruction using hamstring autograft is a standard procedure for restoring knee stability. Graft diameter is a key determinant of surgical success, with smaller grafts associated with higher failure rates. Preoperative prediction of hamstring graft size using simple anthropometric parameters may assist in surgical planning and improve outcomes. OBJECTIVES: To evaluate the relationship between anthropometric measurements and quadrupled hamstring graft diameter in patients undergoing ACL reconstruction. METHODS: This prospective study was conducted at a tertiary care center over 18 months (August 2023-February 2025) and included 48 patients aged 18-55 years undergoing primary ACL reconstruction with hamstring autograft. Preoperative parameters recorded included age, gender, height, weight, body mass index (BMI), and thigh circumference. Graft diameter was measured intraoperatively using a graft sizing block. Statistical analysis was performed using IBM SPSS Statistics for Windows, Version 24 (Released 2016; IBM Corp., Armonk, New York), with p < 0.05 considered significant. RESULTS: The mean age was 40.5 ± 8.3 years, with male predominance (70.8%). Mean height, weight, and BMI were 165.7 ± 6.6 cm, 78.8 ± 7.9 kg, and 24.9 ± 3.9 kg/m², respectively. The mean thigh circumference and graft diameter were 53.0 ± 5.0 cm and 7.91 ± 0.82 mm. Height showed a strong positive correlation with graft diameter (r = 0.666, p < 0.001), while thigh circumference showed a moderate positive correlation (r = 0.367, p = 0.010). BMI demonstrated a significant negative correlation (r = -0.330, p = 0.022). Males had significantly larger graft diameters than females (8.30 ± 0.60 mm vs 6.96 ± 0.41 mm, p < 0.001). CONCLUSION: Anthropometric parameters, particularly height, are reliable predictors of hamstring graft diameter in ACL reconstruction. Preoperative assessment can help identify patients at risk of inadequate graft size and guide surgical planning, including consideration of alternative graft options to optimize outcomes.
