关节镜下RetroButton-同种异体肌腱-界面螺钉重建前交叉韧带的近期疗效

目的探讨关节镜下应用RetroButton-同种异体肌腱-界面螺钉重建前交叉韧带的手术方法与近期疗效。方法 2009年6月-10月,于关节镜下采用RetroButton-同种异体肌腱-界面螺钉重建23例前交叉韧带损伤。男15例,女8例;年龄19～46岁,平均32.5岁。左膝17例,右膝6例。致伤原因:运动伤13例,交通事故伤8例,坠落伤2例。急性损伤(<6周)7例,慢性损伤(>6周)16例。合并单纯内侧半月板损伤11例,单纯外侧半月板损伤6例,内、外侧半月板同时损伤3例,关节软骨损伤5例。患者均无后交叉韧带、内外侧副韧带或后外侧结构损伤。受伤至手术时间3周～32个月。按照Lysholm评分和国际膝关节评分委员会(IKDC)膝关节评分标准进行主观评估;采用Lachman试验和KT-1000关节测量仪检查进行客观评估。结果术后患者切口均Ⅰ期愈合,患膝关节失稳症状明显改善。无高热、感染或明显排斥反应。1例患者术后发生顽固性滑膜炎,关节内反复积液,3周内经关节腔灌洗7次后稳定。患者均获随访,随访时间10～17个月,平均14.7个月。末次随访时IKDC评分、Lysholm评分、Lachman试验及KT-1000检测与术前比较,差异均有统计学意义(P<0.05)。结论关节镜下应用RetroButton-同种异体肌腱-界面螺钉重建前交叉韧带手术操作安全、简便,近期疗效满意。

SHORT-TERM EFFECTIVENESS OF ARTHROSCOPIC ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION WITH RetroButton-ALLOGENEIC TENDON-INTERFERENCE SCREW

Objective To investigate the method and short-term effectiveness of arthroscopic reconstruction of anterior cruciate ligament(ACL) using RetroButton-allogeneic tendon-interference screw.Methods Between June 2009 and October 2009,23 patients with ACL rupture were treated by arthroscopic reconstruction with RetroButton-allogeneic tendon-interference screw.There were 15 males and 8 females with an average age of 32.5 years(range,19-46 years),including 17 left knees and 6 right knees.The injury causes were spor...
