Objective To analyze the clinical effect of minimally invasive therapy on the knee dislocation and multiligament injury. Methods From September 2006 to February 2011 40 patients were treated,32 males and 8 females,aged 16 ~48 years,mean 32 years old. Knee arthroscopic techniques were used in all cases for anterior or posterior cruciate ligament reconstruction, minimally invasive incision in the lateral collateral ligament reconstruction. All patients had preoperative and postoperative Lysholm and IKDC2000 score, to e-valuate knee function recovery. Results All cases were followed up for a mean of 28.4 months ( from 6 months to 40 months ), of which most patients were satisfied with the therapeutic effect, whose mobility and stability of the knees were improved significantly. The average preoperative Lysholm score and the average postoperative Lysholm score( 6. 175 ±4.038 )and( 85. 075 ± 5. 576 ). The excellent and good rate was 87. 5,with a statistically significant difference( t = 84. 828,P < 0. 001 ). According to the IKDC2000 evaluation system, there were Grade D 40 cases before surgery, and Grade A 11 cases, Grade B 25 cases, Grade C 4 cases post surgery. The excellent and good rate was 90% . Conclusion The therapy combining arthroscopy and minimal invasive incision on the knee dislocation and multiligament injury has the merits of minimal invasion,rapid recovery,and satisfactory results.%目的 探讨应用膝关节镜技术并结合关节外微创切口治疗膝关节脱位合并多根韧带损伤的疗效.方法 2006年9月~2011年2月共收治40例患者,其中男性32例,女8例,年龄16~48岁,平均32岁.全部采用膝关节镜技术进行前后交叉韧带重建,微创切口进行内外侧副韧带重建.所有患者术前术后均进行Lysholm和IKDC2000评分,评价膝关节功能恢复情况.结果 所有病例随访平均28.4个月(6～40个月),大多数患者对疗效满意,关节活动度和稳定性明显改善.术前Lysholm得分平均(6.175±4.038)分,术后Lysholm得分平均(85.075±5.576)分,优良率87.5%,差异有统计学意义(t=84.828,P<0.001).术前IKDC2000评分D级40例,术后IKDC2000评分A级11例,B级25例,C级4例,优良率 90%.结论 采用膝关节镜技术并结合小切口治疗膝关节脱位合并多根韧带损伤,具有疗效确切、创伤小、恢复快等特点.
