关节镜技术在青少年急性髌骨脱位治疗中的应用

Arthroscopic surgery for patellar subluxation:surgical outcome of 23 cases

目的：介绍关节镜下微创手术治疗急性髌骨脱位的技术及疗效。方法：2002年5月～2012年6月应用关节镜技术对23例急性髌骨脱位患者进行了关节镜下微创手术治疗，技术要点为关节镜下髌外侧支持带松解，内侧支持带紧缩缝合。患者年龄13（13±19）岁，病程2（2±14）天，随访时间8（3±18）个月。手术前后采用Lysholm评分对膝关节功能进行评定。结果：患者无1例复发脱住。手术前Lysholm评分为55分，手术后提高至90分。结论：关节镜技术既显示了微创优势，同时又对不同程度的髌骨脱位皆获得了满意治疗效果。

Objective：To introduce arthroscopic technique in managing patellar subluxation and its clinical results. Methods：Between May. 2002 and Jun. 2010,21 patients suffered from patellar subluxation underwent arthroscopic surgery The keypointsofour technique are lateral retinaculum release and medial retinaculum shrinking suture. Tibial tuberositywas translated medially The average of all patients was 17 years （rangel3 to30）. The patients suffering from patellarsub -luxation averaged 5 day （range 2 to 14）before operation. They were followed up for average 8 months（ range 3 to 18 ）. The Lysholm score before and after operation was compared in all patients. Resuits ：21 patients were followed up ,and no recurrence was found. Lysholm score of 21 patients was significantly higher after operation than that before operation. Conclusion：Arthroscopic surgery for patellar subluxation achieves excellent outcomes through minimum invasion.
