关节镜下前交叉韧带重建术后失败行翻修术的近中期临床疗效

 目的 探讨关节镜下前交叉韧带重建术后失败行翻修术的近中期临床疗效。方法 回顾性分析武警海警总队医院2013-02至2019-02收治的前交叉韧带重建术后失败行翻修术患者30例(30膝)临床资料,术后平均随访时间37个月(6~70个月)。手术前后膝关节功能采用Lysholm评分、Tegner评分、IKDC评分、KT-2000差值进行分析,采用Lachman试验、前抽屉试验对手术前后膝关节前方稳定性进行分析。结果 Lysholm评分术前(48.33±5.43)分,末次随访(82.92±4.13)分;Tegner评分术前(2.18±0.91)分,末次随访(6.52±1.12)分;IKDC评分术前(48.32±5.54)分,末次随访(76.45±3.86)分;KT-2000屈曲90°差值术前(6.95±1.21)mm,末次随访(2.23±0.84)mm,KT-2000屈曲30°差值术前(6.62±1.01)mm,末次随访(2.34±0.42)mm;差异均有统计学意义(P<0.05)。Lachman试验、前抽屉试验术前30例全部阳性,术后全部阴性,膝关节功能术后提高明显。结论 前交叉韧带重建术后失败行翻修术,近中期疗效满意。

Early and medium-term clinical effects of reconstruction of anterior cruciate ligaments

Objective To evaluate the clinical effects of reconstruction of anterior cruciate ligaments(ACLs).Methods Between February 2013 and February 2019, 30 patients (30 knees) underwent revision surgery after ACL reconstruction failure. All the patients were followed up for 37 months on average (ranging from 6 months to 70 months). The preoperative Lysholm score, Tegner score, IKDC score and KT-2000 arthrometer side-to-side difference and those of the last follow-up were used to evaluate the clinical outcomes. The Lachman test and drawer test were used to evaluate the knee stability.Results The preoperative Lysholm score and that of the last follow-up were respectively (48.33±5.43) points and (82.92±4.13) points, compared to (2.18±0.91) points and (6.52±1.12) points respectively for the Tegner score, and (48.32±5.54) points and (76.45±3.86) points respectively for the IKDC score. The KT-2000 arthrometer side-to-side difference at 90°of flexion was (6.95±1.21) mm before operation, but (2.23±0.84) mm after operation, compared to (6.62±1.01) points before operation, and (2.34±0.42) points after operation at 30° of flexion. The difference was statistically significant (P<0.05). The preoperative Lachman test and drawer test were positive in 30 cases, but negative in all these cases postoperatively.Conclusions The effect of the revision surgery after ACL reconstruction failure is satisfactory.
