Abstract:
The purpose of this meta-analysis was to conduct a comparative analysis of clinical scores and complication rates among patients experiencing recurrent patellar dislocation who underwent medial patellofemoral ligament (MPFL) reconstruction using both single and double tunnel techniques. A comprehensive search was conducted across electronic databases including PubMed, the Cochrane Library, Web of Science, and Google Scholar to retrieve articles relevant to MPFL reconstruction utilising the tunnel technique. Subsequently, meta-analyses were undertaken to assess complication rates and changes in clinical scores before and after surgery. Following this, sensitivity analysis and meta-regression analysis were performed to scrutinise potential confounding variables. A total of thirty-two studies were included in the analysis, comprising twenty-seven non-comparative studies and five comparative studies. The findings revealed a similarity in postoperative complication rates between the single and double tunnel fixation techniques: [9.0% (95%CI, 4.0%-15.6%) versus 8.9% (95%CI, 4.7%-14.1%, p = 0.844)]. Likewise, no statistically significant differences were observed in Lysholm scores [34.1 (95%CI, 26.7-41.5) versus 33.8 (95%CI, 27.7-40.0, p = 0.956)], Kujala scores [29.4 (95%CI, 22.3-36.4) versus 27.3 (95%CI, 22.3-32.3, p = 0.637)], and Tegner score change [1.1 (95%CI, 0.8-1.4) versus 0.7 (95%CI, -0.2-1.6, p = 0.429)] before and after MPFL reconstruction, respectively, using these two techniques. In conclusion, the authors found that the clinical functional improvement and complication rates in MPFL reconstruction using the single tunnel fixation technique are comparable to those achieved with the double tunnel fixation approach. However, to further advance the understanding in this field, additional randomised controlled studies must be conducted to provide further insights.

摘要:
这项荟萃分析的目的是对使用单隧道和双隧道技术进行内侧髌股韧带(MPFL)重建的复发性髌骨脱位患者的临床评分和并发症发生率进行比较分析。对包括PubMed在内的电子数据库进行了全面搜索,Cochrane图书馆,WebofScience,和谷歌学者利用隧道技术检索与MPFL重建相关的文章。随后,进行荟萃分析以评估手术前后的并发症发生率和临床评分变化。在此之后,我们进行了敏感性分析和荟萃回归分析,以仔细检查潜在的混杂变量.共有32项研究纳入分析,包括27项非比较研究和5项比较研究。研究结果表明,单隧道和双隧道固定技术的术后并发症发生率相似:[9.0%(95CI,4.0%-15.6%)与8.9%(95CI,4.7%-14.1%,p=0.844)]。同样,Lysholm评分[34.1(95CI,26.7-41.5)与33.8(95CI,27.7-40.0,p=0.956)]无统计学差异,Kujala得分[29.4(95CI,22.3-36.4)与27.3(95CI,22.3-32.3,p=0.637)],和Tegner评分变化[1.1(95CI,0.8-1.4)与0.7(95CI,-0.2-1.6,p=0.429)]在MPFL重建前后,分别,使用这两种技术。总之,作者发现,使用单隧道固定技术的MPFL重建的临床功能改善和并发症发生率与使用双隧道固定方法的MPFL重建效果相当.然而,为了进一步促进对这一领域的理解,必须进行其他随机对照研究以提供进一步的见解.关键词:MPFL重建,骨隧道,髌骨脱位,Meta分析。
