关节镜下前交叉韧带重建术后翻修的临床研究(附14例报告)

Clinical Study on Renovation after Arthroscopic Anterior Cruciate Ligament Reconstruction(Report of 14 Cases)

目的：探讨关节镜下前交叉韧带（ACL）重建术后翻修手术的开展方式和临床效果。方法：我院2009年1月-2012年9月共收治ACL重建后失稳需翻修的患者14例，均给予关节镜下检查以及翻修手术，术后对患者的治疗情况采用Lysholm评分、Tegner评分、KT-2000及IKDC进行综合评价。结果：患者的KT-2000检查中术前屈曲30°为5．2mm，屈曲90°为3．3mm，术后屈曲30°为3．0mm，屈曲90°为1．6mm；IKDC评分术前为（50±5）分，术后为（72±8）分；Lysholm评分术前为（51±15）分，术后为（77±19）分；Tegner评分术前为（2．6±0．6）分，术后为（4．8±1．2）分。手术前后对比均有显著差异，具有统计学意义（P〈0．05），表明术后患者的膝关节功能明显增强。结论：对ACL重建术失败患者给予术后的翻修可以有效改善患者膝关节功能。

Objective： To study the implement methods and clinical effects of renovation after arthroscopic anterior cruciate ligament （ACL） reconstruction. Methods： 14 cases with postoperative instability after ACL construction who were treated in our hospital from January 2009 to September 2012 were enrolled and taken the arthroscopic examination and revision surgery. Lysholm score, Tegner score, KT-2000 and IKDC were used for the postoperative comprehensive evaluation. Results： The pre-operative KT-2000 examination technique flexion 30 ° was 5.2mm, flexion 90°was 3.3ram, the postoperative flexion 30° was 3.0mm and flexion 90 ° was 1.6mm; the pre-operative IKDC score was （50± 5） and postoperative score was （72± 8）; the Lysholm score before surgery was （5± 15） and （77± 19） after the surgery; the Tegner score before surgery was （2.6± 0.6） and （4.8± 1.2） after the surgery. The differences were statistically significant （P〈0.05）. Conclusion： The renovation surgery after the failure of ACL reconstruction can improve knee function.
