FAST-FIX全内缝合系统治疗膝关节半月板后角损伤中期疗效观察

目的探讨FAST-FIX全内缝合系统治疗膝关节半月板后角损伤的3年中期疗效。方法 2011年1月—2013年4月采用FAST-FIX全内缝合系统治疗膝关节半月板后角损伤并均得到满意随访的患者46例,其中男27例,女19例,年龄17~42 a,平均(23.5±8.22)a。左膝25例,右膝21例,损伤类型:红区损伤33例,红白区损伤13例,其中8例伴交叉韧带损伤。根据Barrett标准评价半月板愈合情况,并用Lysholm评分、IKDC评分、Tegner评分分别评估术后关节功能改善情况。术前Lysholm评分为:(35.73±11.28)分,IKDC评分为:(37.26±13.17)分,Tegner评分为(3.3±1.7)。结果随访时间36~59个月,平均随访46.3个月,随访3年显示42例患者半月板愈合良好,手术成功率91.3%。术后4例患者出现疼痛,其中2例出现绞索,二次手术证实缝合失败并行半月板成形术。术后3年Lysholm评分为:(86.31±11.89)分,IKDC评分为:(82.9±13.44)分,Tegner评分为(5.9±1.9)。术前与术后3年随访评分相比均有统计学意义(P<0.05)。结论 FAST-FIX全内缝合系统治疗膝关节半月板后角损伤3年中期疗效良好。

Arthroscopic repair posterior horn of the meniscus with FAST-FIX suture system:a mid-term clin-ical results report

Objective To evaluate a 3-year mid-term clinical results of FAST-FIX suture system in arthroscopic meniscal posterior horn repair. Methods Clinical results of 46 patients with meniscal tear who underwent posterior horn of the meniscus repair using the FAST-FIX suture system from January 201 1 to April 2013 were retrospectively analyzed. There were 27 males and 19 females,age 17~42 years old,average 23. 5 ±8. 22 years old. There were 25 left knee and 21 right knee and 33 red zone injury and 13 red-white zone injury,8 of which were accompanied by anterior cruciate ligament injury. Clinical healing of the meniscus was assessed by Lysholm scores (35. 73 ±11. 28)points,IKDC scores (37. 26 ±13. 17) points and Tegner scores (3. 3 ±1. 7 ) points before operation. Results The average follow-up period was 46. 3 months (range:36-59 months). The clinical healing rate was 91. 3%. Healing failure occurred to 4 patients and 2 of which had a meniscus noose after operation and were confirmed surgical failure in reoperation. Mean Lysholm scores were (86. 3 1 ± 11. 89),IKDC scores (82. 9 ±13. 44)and Tegner scores (5. 9 ±1. 9)in 3 years after operation for all 46 cases. The differences between the preoperative and postoperative scores in three type scores were statistically significant (P<0. 05 ). Conclusion Arthroscopic posterior horn of the meniscus repair with the FAST-FIX suture system may provide good 3-year mid-term clinical results after operation.
