关节镜下前交叉韧带重建术后疗效及影响因素分析

Efficacy and analysis of determinants after anterior cruciate ligament reconstruction

目的:评估在关节镜下行膝关节前交叉韧带(Anterior cruciate ligament,ACL)重建术的患者术后运动水平恢复情况,并分析其影响因素。方法:选择行ACL自体肌腱重建术患者176例,采用膝关节IKDC评分系统评价患者的患肢功能;随访患者运动水平恢复情况,对可能的影响因素:性别、年龄、体重指数(BMI)、心理素质、文化水平、随访时间、术后膝关节IKDC评分与患者术后运动水平恢复情况之间进行统计学分析,确定其影响作用。结果:(1)患者术后膝关节IKDC评分术前明显改善,差异有统计学意义(P<0.05),其中115例(65.3%)患者术后运动能力恢复至伤前水平,随访时间平均为18.42月。(2)Logistic回归分析显示,患者的性别、年龄、心理素质、IKDC评分是患者行ACL重建术后运动水平恢复的主要影响因素(P<0.05)。结论:年轻、男性、心理素质较好、IKDC评分较高的ACL重建患者术后运动能力更有可能恢复至伤前水平。

Objective:To evaluate the efficacy and correlated factors of ACL reconstruction.Methods:A total of 176 cases who underwent ACL reconstruction were assessed using International Knee Document Committee(IKDC)subjective score.RTS rates were calculated and determinants of RTS were identified,including gender,age,body mass index(BMI),postoperative time,IKDC scores,psychological and cultural level.Results:The postoperative knee IKDC score of patients was significantly improved compared with that before surgery,and the difference was statistically significant(P<0.05).In addition,the postoperative moter ability of 115(63.5%)patients recovered to the pre-injury levels.The Logistic regression analysis showed that age,gender,IKDC scores and psychological factors were the influencing factors of RTS rates.Conclusion:Younger age,male gender,higher IKDC scores and a positive psychological response favoured returning to the pre-injury level of sport.
