Results indicated a significant decrease in femoral tunnel enlargement between groups, favouring the ruptured tissue group. Tibial tunnel enlargement ratios were similar between groups. Clinical outcomes were also not significantly different between groups.

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؟
Recent developments in anterior cruciate reconstruction have focused on achieving anatomic reduction of the AM and PL bundles with hamstring grafts. However, while patients enjoy favourable outcomes, treatment can lead to significant tunnel enlargement and complicate ACL revision surgeries in the long-term. Recently, researchers have observed properties of tendon-bone healing in ruptured ACL tissue (i.e. CD34+ cells). Applications in animal studies have demonstrated a capacity for healing and ability to reduce magnitude of tunnel widening. This study aimed to pilot a technique that utilizes autologous rupture ACL tissue as a graft in a human clinical study.
ما هو سؤال البحث الرئيسي؟
Does the use of a graft, with autologous ruptured ACL tissue sutured to its ends, in anterior cruciate ligament reconstruction decrease tunnel enlargement and improve clinical results when compared to conventional ACLR, 2 years after treatment intervention?
- Tunnel enlargement was significantly less in the ruptured tissue group compared to the conventional (control) group in both femoral tunnels (AM and PL). Femoral AM tunnel enlargement ratios were 84.6% +/- 15.9 and 119.5% +/- 24.1 in the ruptured tissue and control groups respectively (p=0.0283). Ratios for the PL tunnel were 84.2% +/ -14.0 compared to 151.3% +/- 23.8, respectively (p=0.0090).
- Tunnel enlargement for femoral AM and PL tunnels were not significantly different between groups. Enlargement ratios for tibial AM tunnel were 71.0% +/- 11.2% versus 77.8% +/- 15.4% for the ruptured tissue group and control group, respectively, and 65.8% +/- 10.8% versus 96.9% +/- 30.5 for the PL tunnel (p>0.05 for both comparisons).
- Clinical outcome measures at 2 years postoperative did not differ significantly between the ruptured tissue group and control group: Mean Lysholm scores were 92.6 vs 93.0, respectively, anterior knee stability 1.4 vs 1.0, and pivot-shift test results 4/5 in both groups (p>0.05 for all).
ما الذي يجب أن أتذكره أكثر؟
Tunnel enlargement of the femoral AM and PL tunnels were both significantly reduced in the ruptured tissue group compared to the conventional group. Tibial tunnel enlargement was comparable between techniques. Additionally, Lysholm scores, anterior knee stability, and pivot-shift tests were not significantly different between groups.
كيف سيؤثر ذلك على رعاية مرضاي؟
Double-bundle ACLR using grafts of autologous ruptured ACL tissue sutured to doubled semitendinosus tendons appeared to yield less femoral tunnel widening while providing similar clinical outcomes when compared to a conventional technique. Findings from this pilot study warrant larger next-phase trials in populations of a wider age range. Additionally, further research is needed to elicit the healing mechanism of this technique.
