A Preclinical Model to Study the Influence of Graft Force on the Healing of the Anterior Cruciate Ligament Graft

In conclusion, we have developed a novel ACL reconstruction model that can reproducibly produce two ACL graft force patterns. This model would permit further research on how ACL graft forces may affect subsequent graft healing, maturation, and function.

ConclusionsThe findings of this study showed that anterior knee laxity is restored with revision BPTB autograft ACLR after failed primary HT autograft ACLR, in the same cohort of patients. However, revision ACLR showed a significantly inferior functional knee outcome compared with primary ACLR. It is important for clinicians to inform and set realistic expectations for patients undergoing revision ACLR. Patients must be aware of the fact that having revision ACLR their knee function will not improve as much as with primary ACLR and the final postoperative functional outcome is inferior.Level of evidenceRetrospective cohort study, Level III.

ConclusionAfter 6  months of follow-up, hamstring tendon autografts for anatomic ACL reconstruction do not show equal MRI signal intensity compared to a healthy ACL and should therefore be considered immature or at least not completely healed even if clinical laxity measurement provides good results. However, in the case of a competitive athlete, who is clinically stable and wants to return to sports at 6 months, performing an MRI to confirm the stage of graft healing might be an option.Level of evidenceProspective, comparative study II.

Publication date: Available online 11 June 2018Source: Arthroscopy TechniquesAuthor(s): Avinesh Agarwalla, Richard Puzzitiello, Grant H. Garcia, Brian ForsytheAbstractAnterior cruciate ligament (ACL) reconstruction with a bone–patellar tendon–bone autograft yields good clinical outcomes. Despite appropriate clinical outcomes, the most common complaint after reconstruction with a bone–patellar tendon–bone autograft is anterior knee pain at the donor graft sites. Synthetic bone grafts, such as beta-tricalcium phosphate (β-TCP), have been previously used to fill the bony defect in fractures as wel...

Publication date: May 2018Source: Arthroscopy Techniques, Volume 7, Issue 5Author(s): Patrick E. Jones, Dustin J. SchuettAbstractAnterior cruciate ligament (ACL) tears represent one of the most common sports-related injuries in the young population. There are multiple studies showing higher failure rates in the younger population with an allograft supporting the routine use of an autograft. In addition, higher failure rates have been shown with grafts narrower than 8 mm in diameter. This places the surgeon in an operative dilemma determining what to do with a narrow graft or an attenuated hamstring during harvest. All...

SelimAbstractAn untreated posterolateral corner (PLC) injury in patients with a torn anterior cruciate ligament (ACL) may be a leading cause of ACL reconstruction failure. Combined ACL and PLC reconstruction is discussed in few studies in the literature. Femoral tunnel intersection in combined reconstruction has been reported to be high. Short grafts may render combined reconstruction undoable. This Technical Note describes a technique that allows a combined ACL and PLC reconstruction. The ACL graft is a 4-stranded hamstring tend...

McGahan, James L. ChenAbstractAnterior cruciate ligament (ACL) ruptures are common and unfortunate injuries for many athletes. The standard therapy for ACL rupture is ACL reconstruction with either autograft, harvested from hamstring or patellar tendon, or allograft tendon from a tissue donor. Advances in tissue engineering have produced interventions to augment the healing process and may have applications when it comes to ACL reconstruction...
