Results revealed that the double-bundle technique led to better outcomes in rotational laxity (measured by the pivot-shift test, KT and IKDC grading). However, no significant difference was observed between the two techniques in terms of functional recovery.

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؟
While the single-bundle technique has been considered the gold standard for ACL reconstruction, a failure rate of 11-30% with persistent instability of the knee has been reported. The double-bundle technique was proposed to overcome these limitations, where the treatment was able to more closely restore normal kinematics to the knee. However, previous clinical results comparing these two techniques were riddled with controversial results. Therefore, this meta-analysis aimed to compare the outcome of single- and double-bundle reconstruction of the ACL.
ما هو سؤال البحث الرئيسي؟
Did a double-bundle ACL reconstruction technique lead to better clinical and functional outcomes than the single-bundle technique?
- According to 10 studies, a significant difference in Pivot shift grading between single and double-bundle techniques was observed (OR, 0.27, 95% CI 0.20, 0.36; P = 0.000, I-squared = 67.3%).
- 2 trials indicated significant differences in KT grading between the two reconstruction techniques (OR, 0.44, 95% CI 0.21, 0.95; P = 0.035, I-squared = 0.00%).
- 6 studies reported a significant difference in IKDC grading between the two methods (OR, 0.59, 95% CI 0.40, 0.87; P = 0.008, I-squared = 0.00%).
- No significant differences were observed in complications, IKDC scores, Lysholm Knee scores, and Tegner activity scores between the two treatments.
- While no significant difference was observed in KT arthrometer between the groups (from 9 studies), none of the co-variables (year P = 0.439, study type P = 0.764) could explain heterogeneity by meta-regression, and the heterogeneity may be due to different follow-up.
ما الذي يجب أن أتذكره أكثر؟
This study demonstrated that double-bundle ACL reconstruction led to better outcomes in rotational laxity (assessed through the pivot-shift test, KT and IKDC grading) compared to the single-bundle technique. However, no significant difference was observed in functional outcome measures such as IKDC scores, KT arthrometer, Lysholm knee, or Tegner activity scores.
كيف سيؤثر ذلك على رعاية مرضاي؟
The double-bundle ACL reconstruction technique seems to be superior to the single-bundle method in terms of objective measures. However, the reliability of these findings is uncertain as the methodological quality of the included RCTs was difficult to assess (due to lack of randomization and concealment). Furthermore, it is unclear how more 'anatomic' single bundle reconstruction techniques fare against the double-bundle techniques. As clinical results seem equivalent based on available data, further results could be aimed at determining if the suggested improvement in mechanical stability affords improved clinical benefits in some population groups (i.e. high performance athletes).
