Femoral tunnel increase smaller with interference screw versus cortical button fixation in ACLR .
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2018;6(2):15 Knee. 2017 Oct;24(5):1047-105433 patients scheduled for ACL reconstruction were included in this study to compare the effects of different fixation methods on postoperative tunnel widening. Patients were randomized to reconstruction using aperture screw fixation or suspensory cortical button fixation. Tunnel volume was measured over a 6 month period using MRI and CT scans. The results at 6 months indicated no differences between the two groups for tibial tunnel volume (117.7+/-24.1% button group vs. 113.9+/-10.3% screw group (p=0.565)). While the femoral tunnel volume at 6 months was significantly greater in the button group (143.2+/-34.4%) compared to the screw group (119.8+/-19.2%) (p=0.023).

مؤشر الهشاشة هو أداة تساعد في تفسير النتائج المهمة، وتوفر مقياسًا لقوة النتيجة. ويمثل مؤشر الهشاشة عدد الأحداث المتتالية التي يجب إضافتها إلى نتيجة ثنائية التفرع لجعل النتيجة غير مهمة. يمثل الرقم الصغير نتيجة أضعف ويمثل الرقم الكبير نتيجة أقوى.
لماذا كانت هناك حاجة لهذه الدراسة الآن؟
Anterior cruciate ligament (ACL) reconstruction is often undergone following a tear. Various methods of graft fixation are available in these procedures. Recently, there has been an interest in whether the type of graft fixation used influences widening of either the femoral or tibial bone tunnels.
ما هو سؤال البحث الرئيسي؟
In ACL reconstruction, does change in tunnel volume after 6 months significantly differ between graft fixation with bioabsorbable interference screws and suspensory extra-cortical button fixation?
- On MRI, the percent change in tibial tunnel volume from baseline to 6 months did not significantly differ between the button group (96.4+/-19.0%) and the screw group (108.0+/-14.9%) (p=0.060). Similarly, on CT, the percent change in tibial tunnel volume from baseline to 6 months did not significantly differ between the button group (117.7+/-24.1%) and the screw group (113.9+/-10.3%) (p=0.565).
- On MRI, the percent change in femoral tunnel volume from baseline to 6 months was significantly greater in the button group (154.3+/-38.0%) compared to the screw groups (110.9+/-20.7%) (p<0.001). Similarly, on CT, the percent change in tibial tunnel volume from baseline to 6 months was significantly greater in the button group (143.2+/-34.4%) compared to the screw group (119.8+/-19.2%) (p=0.023).
ما الذي يجب أن أتذكره أكثر؟
In ACL reconstruction, graft fixation with adjustable-length loop cortical buttons demonstrated significantly greater femoral tunnel volume increase within the first 6 months after surgery when compared to fixation with absorbable interference screws. Both types of fixation demonstrated similar degrees of tibial tunnel volume increase in the first 6 months after surgery.
كيف سيؤثر ذلك على رعاية مرضاي؟
The results of this study suggest that short-term enlargement of the femoral tunnel may be larger with the use of an adjustable-length loop cortical button as opposed to a bioabsorbable interference screw in ACL reconstruction. Nevertheless, there is still considerable debate on the correlation between tunnel widening and clinical outcomes in these cases. Follow-up studies over the longer term are needed to determine if early tunnel enlargement is associated with latent complications after ACL reconstruction.
