The purpose of this study was to prospectively assess the outcome of hamstring autograft anterior cruciate ligament (ACL) reconstruction by use of identically shaped bioabsorbable and titanium interference screws in a randomized trial.
One hundred patients were randomized to have either bioabsorbable or titanium interference screws used for graft tunnel fixation in hamstring autograft ACL reconstruction. Patients were objectively and subjectively assessed preoperatively and 3, 6, 12, and 24 months postoperatively. Radiographs at 12 months postoperatively were also assessed for tunnel width.
There were no differences in clinical outcome by use of Lysholm and International Knee Documentation Committee scores between the 2 groups at any stage of follow-up to 2 years. Tibial tunnel widths were the same between the 2 groups. There was slightly more tunnel widening in the femur when bioabsorbable interference screws were used.
Identically shaped bioabsorbable interference screws and titanium interference screws used for hamstring autograft ACL reconstruction are equally successful up to 2 years postoperatively.
Level I, prospective randomized trial with more than 80% follow-up.
本研究的目的是在一项随机试验中，前瞻性地评估使用形状相同的生物可吸收螺钉和钛合金干涉螺钉进行自体腘绳肌腱前交叉韧带（ACL）重建的结果。
100例患者被随机分为两组，分别在自体腘绳肌腱ACL重建中使用生物可吸收螺钉或钛合金干涉螺钉进行移植物隧道固定。在术前以及术后3、6、12和24个月对患者进行客观和主观评估。术后12个月时还对X线片进行隧道宽度评估。
在长达2年的随访的任何阶段，两组间使用Lysholm评分和国际膝关节文献委员会评分评估的临床结果均无差异。两组间胫骨隧道宽度相同。使用生物可吸收干涉螺钉时，股骨隧道增宽略多。
用于自体腘绳肌腱ACL重建的形状相同的生物可吸收干涉螺钉和钛合金干涉螺钉在术后2年内同样成功。
I级，随访率超过80%的前瞻性随机试验。
