采用股四头肌腱-骨、骨-髌腱-骨及腘绳肌腱自体移植物行前交叉韧带重建术后6个月和12个月股四头肌力量恢复的相关因素
简介
该研究纳入154例前交叉韧带重建（ACLR）患者，比较股四头肌腱-骨（QTB）、骨-髌腱-骨（BPTB）和腘绳肌腱（HT）三种自体移植物术后6个月和12个月的股四头肌力量恢复情况。关键发现：术后6个月，使用QTB（OR=0.11）或BPTB（OR=0.12）移植物、行半月板缝合术以及术前Tegner活动评分较低，是股四头肌力量恢复不良（≤90%）的独立危险因…
英文摘要
BACKGROUND: Anterior cruciate ligament reconstruction (ACLR) using a quadriceps tendon with bone (QTB) autograft has been associated with reduced quadriceps strength at 6 months postoperatively compared to other autograft options. However, limited studies have assessed strength recovery after return to sports after ACLR, particularly involving QTB autografts. PURPOSE: To examine factors influencing quadriceps strength recovery at 6 and 12 months after ACLR using QTB, bone-patellar tendon-bone (BPTB), and hamstring tendon (HT) autografts. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Individuals who underwent primary ACLR using QTB, BPTB, or HT autografts, had a preinjury Tegner activity scale (TAS) score >5, and completed at least 12 months of follow-up were included. Participants were classified into recovery (>90%) and nonrecovery (≤90%) groups based on the limb symmetry index of quadriceps strength compared to the contralateral leg at 6 and 12 months post-ACLR. Variables associated with quadriceps strength recovery at these time points were analyzed. RESULTS: A total of 154 participants were included. Multivariable logistic regression showed that use of QTB (OR, 0.11; P < .001) or BPTB (OR, 0.12; P < .001) autografts, meniscal repair (OR, 0.34; P = .013), and lower preinjury TAS score (OR, 1.68; P = .011) were associated with a significantly increased risk of quadriceps strength deficit at 6 months after ACLR. At 12 months after ACLR, lower preinjury TAS score (OR, 1.48; P = .046) and lower Knee injury and Osteoarthritis Outcome Score (KOOS) pain at 3 months (OR, 1.09; P = .002) were associated with a significantly increased risk of quadriceps strength deficit. The receiver operating characteristic curve showed that a KOOS pain value at 3 months after ACLR of 83.1 points was the cutoff for indicating a strength deficit at 12 months (sensitivity, 78.4%; specificity, 59.1%). CONCLUSION: Use of QTB or BPTB autografts, meniscal repair, and lower preinjury TAS score were factors associated with quadriceps strength deficit at 6 months after ACLR. At 12 months, lower preinjury TAS score and lower KOOS pain at 3 months were factors associated with persistent strength deficit.
