关节镜下个体化前交叉韧带单束与双束解剖重建的近期疗效比较

目的 探讨关节镜下个体化单束与双束解剖重建前交叉韧带(ACL)的技术,并比较二者的近期疗效.方法回顾性分析2007年3月到2009年9月行ACL个体化单、双束解剖重建且获得随访的117例ACL损伤患者资料,根据不同解剖重建方法分为两组:A组(个体化单束解剖重建)35例,男31例,女4例;平均年龄(28.6±5.1)岁.B组(个体化双束解剖重建)82例,男73例,女9例;平均年龄(27.6±5.4)岁.两组患者术前一般资料比较差异均无统计学意义(P>0.05),具有可比性.采用Lachman试验、轴移试验、KT-2000、国际膝关节评分委员会(IKDC)评分及Lysholm评分比较两组患者的疗效.结果 117例患者术后获11～25个月(平均15个月)随访.末次随访时Lachman试验结果:与健侧比较,A组完全正常者占88.6%(31/35),B组占95.1%(78/82);轴移试验结果:与健侧比较,A组完全正常者占88.6%(31/35),B组占96.3%(79/82);Lysholm评分:A组平均为(93.4±8.2)分,B组平均为(93.7±7.0)分,以上指标两组比较差异均无统计学意义(P>0.05).而KT-2000检测结果:A组平均为(1.4±0.6)mm,B组平均为(1.1±0.5)mm;A组IKDC评分正常者(A级)占71.4%(25/35),B组占93.9%(77/82),两组比较差异均有统计学意义(P<0.05).结论采用个体化解剖位双束重建能更好地恢复患者膝关节的稳定性.双束解剖重建术中ACL股骨与胫骨足迹、髁间窝宽度的判断对手术的设计至关重要,3入路技术、测量尺的应用是个体化ACL双束解剖重建的关键所在.

Abstract：

Objective To compare clinical outcomes of double-bundle and single-bundle in individualized arthroscopic anatomical reconstruction of anterior cruciate ligament (ACL) . Methods The clinical data of 117 patients were reviewed who had received double-bundle or single-bundle arthroscopic ACL reconstruction from March 2007 through September 2009 in our hospital and had undergone complete follow-up. Of them, 35 cases had single-bundle ACL reconstruction and 82 double-bundle reconstruction. In the single-bundle group(group A), there were 31 men and 4 women, aged 28. 6 ±5. 1 years. In the double-bundle group(group B), there were 73 men and 9 women, aged 27. 6 ±5. 4 years. The 2 groups were comparable in the preoperative demographic data ( P > 0. 05). To evaluate the outcomes, Lachman and Pivot Shift exams , KT-2000, Lysholm and IKDC (International Knee Documentation Committee) scores, were adopted. Results The 117 patients received a mean follow-up of 15 months (from 11 to 25 months). The Lachman test showed 88. 6% (31/35) were normal in group A and 95. 1% (78/82) were normal in group B.The pivot-shift test showed 88. 6%(31/35) were normal in group A and 96. 3% (79/82) were normal in group B. Group A had a mean Lysholm score of 93. 4 ± 8. 2 and group B a mean Lysholm score of 93. 7 ±7. 0. There were no significant differences between the 2 groups in the above indexes ( P > 0. 05). By IKDC score, 71. 4% (25/135) were normal in group A and 93. 9% (77/82) were normal in group B. The KT-2000 test showed a mean of 1. 4 ± 0. 6 mm in group A and a mean of 1. 1 ± 0. 5 mm in group B. These 2 values were significantly different between the 2 groups ( P < 0. 05). Conclusions The individualized arthroscopic double-bundle anatomical reconstruction of ACL can maximally restore the anteroposterior and rotational stability. Arrangement of the ACL insertion site on the femoral and tibial side, three-portal technique and ruler application are keys for individualized anatomical double-bundle ACL reconstruction.
