Abstract：
The Stability Study was a multicenter, pragmatic, parallel groups, randomized clinical trial comparing hamstring tendon autograft anterior cruciate ligament reconstruction with or without the addition of lateral extra-articular tenodesis in young patients at high risk of graft failure. Having recruited 618 patients with a 5% loss to follow up, we were able to demonstrate a clinically and statistically significant reduction in clinical failure and graft rupture at 2 years postoperative. No differences in patient-reported outcomes (PROs) were demonstrated between groups; however, patients who experienced an adverse event had significantly worse PROs than those who did not.
摘要：
稳定性研究是一个多中心，务实,平行组,随机临床试验比较年轻患者移植失败的风险较高的患者在添加或不添加外侧关节外肌腱固定术的情况下自体肌腱移植前交叉韧带重建。招募了618名5%的患者进行随访，我们能够证明在术后2年时临床失败和移植物破裂的临床和统计学上显著减少.患者报告的结果(PRO)在组间没有差异;然而,发生不良事件的患者的PRO显著低于未发生不良事件的患者.
