Brett Fritsch, Francisco Figueroa, Bertrand Semay
Hamstring autografts are frequently used for anterior cruciate ligament reconstruction. The inherent variability in graft diameter has been stated as a disadvantage in its use because the presence of smaller graft diameters has been correlated with increased risk of re-rupture. Several techniques have been described to address this concern. Modifications of the basic Graftlink technique allows for increased control over final graft diameter using a standard harvest of the semitendinosus tendon with or without the gracilis tendon, and results in a graft of adequate length and diameter in all patients with rigid cortical fixation on the femur and tibia...

BACKGROUND: No well-controlled studies have compared the long-term outcome of anterior cruciate ligament (ACL) reconstruction with hamstring tendon autograft between adolescents and adults. Increased posterior tibial slopes (PTSs) have been reported in the ACL-injured versus controls, but the effect of PTS on the outcome after reconstruction is relatively unexplored. PURPOSE: To compare the prospective longitudinal outcome of "isolated" ACL ruptures treated with anatomic endoscopic ACL reconstruction using hamstring tendon autograft over 20 years in adolescent and adult cohorts and to examine factors for repeat ACL injury...

Although initially considered rare, anterior cruciate ligament (ACL) ruptures in pediatric patients recently have increased substantially as a result of greater awareness of the injury and increased participation in youth sports. Although pediatric patients with an ACL injury and a clinically stable joint may handle the injury well and return to sports activity without requiring surgical reconstruction, young, active patients with an ACL rupture and an unstable joint may be good candidates for ACL reconstruction to prevent ongoing instability and additional joint damage...

Anterior cruciate ligament (ACL) deficient patients have an increased rate of patellofemoral joint (PFJ) osteoarthritis (OA) as compared to the general population. Although the cause of post-injury OA is multi-factorial, alterations in joint biomechanics may predispose patients to cartilage degeneration. This study aimed to compare in vivo PFJ morphology and mechanics between ACL deficient and intact knees in subjects with unilateral ACL ruptures. Eight male subjects underwent baseline MRI scans of both knees...

Knee laxity may be impacted by rupture of the anterolateral knee ligament (ALL). The goal of this study was to measure tibial translation and rotation as a function of the status of the ALL and the anterior cruciate ligament (ACL). Five pairs of fresh frozen cadaver specimens were analyzed. The knee was positioned in 20° flexion. Calibrated posteroanterior forces and internal/external torques were successively applied. Anterior tibial translation and total internal/external tibial rotation were measured with a navigation system...

BACKGROUND: Although there are several causes of unplanned return to the operating room (RTOR) following pediatric anterior cruciate ligament (ACL) reconstruction (ACLR), prior outcomes studies focus primarily on the risk of graft failure. We sought to comprehensively describe indications for RTOR in pediatric primary ACLR patients, estimate associated rates of RTOR, and assess the impact of concomitant meniscal procedures on these rates. METHODS: This retrospective cohort study considered patients who underwent primary ACLR at an urban, pediatric tertiary care hospital between 2013 and 2015...

The anterior cruciate ligament (ACL) is cited as the most frequently injured ligament in the knee. The standard treatment of ACL injury remains ligament reconstruction followed by a postoperative physiotherapeutic procedure. During the reconstruction, the torn ligament can be replaced with an autograft or an allograft. A synthetic ligament is also one of the available graft options. Synthetic grafts in ruptured ACL treatment have been used as scaffolds, stents, or prostheses. The story of using synthetic materials in ACL deficient knee treatment started in the beginning of the 20th century with the usage of silk and silver fibers...
