Analysis of tunnel widening after double-bundle ACL reconstruction

Abstract

Therapeutic case series, Level IV.

RETRACTED ARTICLE: Comparison of double-bundle anterior cruciate ligament reconstruction with and without autologous conditioned serum application

“…The present study was particularly concerned about the biological aspect of ACL graft integration. Bone tunnel diameters increase significantly over time, confirming previously published studies [4,23,41,42]. Lee et al [23] found that the tunnel entrance upon DB ACL reconstruction was the most widened area.…”

“…Bone tunnel diameters increase significantly over time, confirming previously published studies [4,23,41,42]. Lee et al [23] found that the tunnel entrance upon DB ACL reconstruction was the most widened area. This finding supports the hypothesis that osteoclastic effects of synovia may [initially] appear at the region closest to articulation.…”

MRI evaluation of the four tunnels of double-bundle ACL reconstruction

“…Our results of tunnel enlargement are higher than in previous studies on DB ACL reconstruction tunnel enlargement (4)(5)(6)(7)(8)12). The results of our study compared to previous studies are shown in Table 4.…”

“…MRI has also been used in the evaluation of DB ACL reconstruction tunnel enlargement (4)(5)(6)(7)(8), and in a prior study was used to evaluate tunnel locations in single-bundle (SB) ACL reconstruction (9).…”

“…Tunnel enlargement occurs postoperatively in both SB (10)(11)(12) and DB ACL reconstructions (4)(5)(6)(7)(8)12). Its etiology is unknown but it is thought to be multifactorial with mechanical and biological factors (6,13,14).…”
