Purpose The clinical relevance and mechanisms of local bone loss early post-anterior
cruciate ligament (ACL) reconstruction remain unclear. The early spatial and temporal …

Introduction A calcium phosphate (CaP)-hybridized tendon graft improves tendon-to-bone
healing. The purpose of the study was to evaluate the progression of morphological …

Background Revision anterior cruciate ligament (ACL) reconstruction requires a precise
evaluation of previous tunnel locations and diameters. Enlargement of the tunnels, despite …

Background Bone tunnel enlargement is a phenomenon present in all anterior cruciate
ligament (ACL)-reconstruction techniques. It was hypothesized that press-fit fixation using a …

Background Bone tunnel enlargement following primary anterior cruciate ligament (ACL)
reconstruction with soft tissue graft might be a severe disadvantage for revision surgery. The …

Abstract Changes in the femoral and tibial bone tunnel were studied prospectively after
arthroscopic ACL reconstruction with quadruple hamstring autograft. To determine whether …

The mechanism of bone tunnel enlargement following anterior cruciate ligament (ACL)
reconstruction is not yet clearly understood. Many authors hypothesized that aggressive …

The purpose of this study was to retrospectively investigate the effects of variations in the
length of the tendon within the tibial tunnel on tunnel widening (TW) following anatomical …

The exploration of methods to improve healing of a tendon graft in a bone tunnel in anterior
cruciate ligament reconstruction has been a subject of basic and translational research for …

Bone tunnel fixation of a soft tissue tendon graft is the weak link immediately following ACL
reconstruction. This biomechanical study evaluated the influence of extraction drilled or step …
