Current evidence around patellar tendon graft in ACLR for high-risk patients: current concepts Open
Hamstrings and patellar tendon (PT) are the most common autografts used to perform anterior cruciate ligament (ACL) reconstructions. The debate to know which graft should be better has been going on for decades. However, in relation to und…
View article: Risk Factors for Revision Anterior Cruciate Ligament Reconstruction and Frequency With Which Patients Change Surgeons
Risk Factors for Revision Anterior Cruciate Ligament Reconstruction and Frequency With Which Patients Change Surgeons Open
Background: Revision surgery is a known complication after anterior cruciate ligament (ACL) reconstruction (ACLR), but the proportion of patients who seek a different surgeon for their revision procedure is unknown. Purpose: To determine t…
View article: The influence of tibial slope on anterior cruciate ligament graft failure risk is dependent on graft positioning
The influence of tibial slope on anterior cruciate ligament graft failure risk is dependent on graft positioning Open
Background: Increased lateral tibial posterior slope (LTPS) is associated with higher anterior cruciate ligament (ACL) reconstruction (ACLR) failure rate. Transportal central femoral footprint ACLR is associated with higher failure rate co…
View article: The Ratio of Tibial Slope and Meniscal Bone Angle for the Prediction of ACL Reconstruction Failure Risk
The Ratio of Tibial Slope and Meniscal Bone Angle for the Prediction of ACL Reconstruction Failure Risk Open
Background A growing body of research is indicating that the tibial slope and the geometry of the tibiofemoral meniscal–cartilage interface may affect the risk of anterior cruciate ligament reconstruction (ACLR) failure. Increased lateral …
