腓骨长肌腱与腘绳肌腱自体移植物在关节镜下前交叉韧带重建中的比较：一项随机对照研究
简介
一项随机对照研究比较腓骨长肌腱（PLT）与腘绳肌腱（HT）自体移植物在关节镜下ACL重建中的效果，各81例。PLT取腱时间显著更短（7.13 vs 24.37 min），移植物更长更粗，术后12个月Lysholm评分两组无显著差异，PLT组AOFAS 6个月恢复近基线且供区并发症更少。提示PLT可作为ACL重建的可靠移植物替代选择。
英文摘要
BACKGROUND: Hamstring tendon autograft is widely used for anterior cruciate ligament (ACL) reconstruction, but concerns persist regarding graft size, harvest duration, and donor-site morbidity. Peroneus longus tendon (PLT) autograft has emerged as a potential alternative. This study compared PLT and hamstring tendon (HT) autografts in arthroscopic ACL reconstruction. METHODS: A randomised controlled study was conducted at a tertiary orthopaedic centre. Adults with ACL rupture were allocated to HT (n = 81) or PLT (n = 81) autograft. Primary outcomes included graft harvest time and graft dimensions. Secondary outcomes included the Lysholm knee score, the American Orthopaedic Foot and Ankle Society (AOFAS) score, thigh circumference, and donor-site morbidity. Follow-up was performed at 1, 6, and 12 months. RESULTS: PLT harvest was significantly faster than HT (7.13 ± 2.30 vs 24.37 ± 4.85 min; p < 0.05). PLT grafts were significantly longer and thicker (p < 0.05). Both groups demonstrated substantial improvement in Lysholm scores, with no significant difference at 12 months (p = 0.53). AOFAS scores in the PLT group returned to near-baseline by 6 months. The HT group exhibited significant thigh hypotrophy and one surgical site infection. CONCLUSION: PLT autograft provided faster harvest, larger graft dimensions, and lower donor-site morbidity while achieving comparable early functional outcomes to HT autograft. PLT represents a reliable alternative graft option for arthroscopic ACL reconstruction.
