Many clinicians believe that the results of revision anterior cruciate ligament (ACL) reconstruction compare unfavorably with primary ACL reconstruction. However, few prospective studies have evaluated revision ACL reconstruction using validated patient-based metrics. This study was performed to evaluate and compare the results of revision ACL reconstruction and primary ACL reconstruction. The ...
In anterior cruciate ligament (ACL) reconstruction, slow graft maturation may result in graft failure or elongation during the postoperative rehabilitation period. Vascular endothelial growth factor (VEGF) is a potent mediator of angiogenesis. The findings of recent studies suggest that VEGF application is a potential strategy to accelerate angiogenesis in the graft after ACL reconstruction. Ho...
Integration of hamstring tendon graft with bone in reconstruction of the anterior cruciate ligament.
Anterior cruciate ligament (ACL) reconstruction using four-strand hamstring graft with round-headed, cannulated, interference (RCI) screw fixation requires osteointegration of the tendon graft. This report describes the histology at the bone-tendon junction of two specimens retrieved from patients undergoing revision surgery after traumatic mid-substance ACL graft rupture at 6 and 10 weeks afte...
PURPOSE To report outcomes of revision anterior cruciate ligament (ACL) reconstruction using tibial or hamstring tendon allografts and to compare with another study using non-irradiated fresh-frozen bone-patellar tendon-bone allografts. METHODS Records of 12 men and 7 women aged 18 to 53 (mean, 33) years who underwent revision ACL reconstructions using tibial tendon (n=17) or hamstring tendon...
BACKGROUND The purpose of this study was to compare the initial stability of anatomical and non-anatomical single bundle anterior cruciate ligament (ACL) reconstruction and to determine which would better restore intact knee kinematics. Our hypothesis was that the initial stability of anatomical single bundle ACL reconstruction would be superior to that of non-anatomical single bundle ACL recon...
BACKGROUND Revision anterior cruciate ligament (ACL) reconstruction surgery occurs in 5% to 15% of individuals undergoing ACL reconstruction. Identifying predictors for revision ACL surgery is of essence in the pursuit of creating adequate prevention programs and to identify individuals at risk for reinjury and revision. PURPOSE To determine predictors of revision ACL surgery after failed pri...
Thomas J. Gill, MD ABSTRACT Revision anterior cruciate ligament (ACL) reconstruction poses a challenging situation for the surgeon. First and foremost, a diagnosis as to why the index reconstruction failed must be made – was this simply the result of a new trauma, or were there technical, diagnostic, or biological considerations associated with the index surgery that predisposed it to failure. ...
Rupture of the anterior cruciate ligament (ACL) is one of the most frequent forms of knee trauma. The traditional surgical treatment for ACL rupture is single-bundle reconstruction. However, during the past few years there has been a shift in interest toward double-bundle reconstruction to closely restore the native ACL anatomy. This paper evaluates the basis for double-bundle ACL reconstructio...
Background: The goal of this study was to evaluate, functional capacity of the knee in flexion and internal rotation after hamstring ligament harvest for Anterior Cruciate Ligament (ACL) reconstruction.Methods: Fifty patients (male and 18-45 years old) with isolated ACL injury, randomly allocated in two equal groups (in one group, ACL reconstruction was performed with Tibialis Posterior allogra...
