There are currently no longitudinal data describing the pre- and postoperative postural regulation and stability of patients with anterior cruciate ligament (ACL) damage. Therefore, the aim of this study was to evaluate postural regulation and stability prior to and during rehabilitation following surgery of the ACL. Fifty-four physically active subjects (age: 30.5±10.9 years, 29 male subjects) were examined with the Interactive Balance System pre-, 6, and at 12 weeks following surgical reconstruction of the ACL using a hamstring tendon graft...

BACKGROUND: Revision anterior cruciate ligament (ACL) reconstruction in pediatric patients has not been well studied. The purpose of this study was to assess the demographics, technique, and results of ACL revision surgery in children and adolescents. METHODS: This was a retrospective case series with outcomes assessment of patients 18 years old and younger who underwent revision ACL surgery over a 16-year period at a single institution. Medical records were reviewed for demographics, clinical and operative data, and patients were contacted for outcomes at a minimum of 1 year after revision surgery...

PURPOSE: The present study aimed to compare 2- and 5-year outcomes of ACL reconstruction between patients with and without generalized joint laxity and to perform comparative evaluation between two types of grafts used for ACL reconstruction in patients with generalized joint laxity. METHODS: Two hundred and thirty-seven patients who underwent ACL reconstruction from 2001 to 2008 were included. Patients were classified into two groups according to the presence or the absence of generalized joint laxity, and further subdivided into two subgroups based on the type of graft used: bone-patellar tendon-bone (BPTB) or hamstring...

Background: Accumulating evidence suggests that long-term anterior cruciate ligament (ACL) deficiency can give rise to an abnormal tibiofemoral relationship and subsequent intra-articular lesions. However, the effects of chronic ACL deficiency (ACLD) on early graft failure after anatomic reconstruction remain unclear. Hypothesis: We hypothesized that patients with long-term ACLD lasting more than 5 years would have a greater rate of early graft failure due to insufficient intraoperative reduction of the tibia and that the preoperative and immediately postoperative abnormal tibiofemoral relationship in the sagittal plane, such as anterior tibial subluxation (ATS), would correlate with the graft status on postoperative magnetic resonance imaging (MRI)...

CONTEXT: Recent epidemiology studies indicated a steady increase of anterior cruciate ligament (ACL) injury in young athletes. ACL reconstruction (ACLR) is currently a standard of the care, but effect of ACLR graft including bone patellar tendon bone (BTB), hamstring tendon (HT), or iliotibial band (ITB) on balance and hop performance is understudied. OBJECTIVE: To compare balance and hop deficits between uninvolved and reconstructed limbs in each autograft type (aim 1) and among the three autograft groups (aim 2)...

BACKGROUND The aim of this study was to evaluate the reconstruction of a torn anterior cruciate ligament (ACL) with 10 mm diameter BPTB (bone-patellar tendon-bone) autograft versus 8 mm HT (hamstring tendon) autografts, to compare the ability to restore pre-injury sports activities and reduce revision risk after these procedures. MATERIAL AND METHODS A prospective clinical review was performed to compare results of patients who underwent primary anatomical ACLR with 10 mm BPTB autografts with patients who underwent 8 mm diameter HT autografts, between January 2011 and January 2014...

BACKGROUND: The hamstring tendons are commonly harvested for anterior cruciate ligament (ACL) reconstruction with detachment of the tibial insertion. Retaining the insertion may help to preserve vascularity and viability of the graft and bypass the stages of avascular necrosis and revascularization, which might be beneficial to graft maturity. PURPOSE: To investigate and compare graft maturity by magnetic resonance imaging (MRI) after ACL reconstruction with preservation or detachment of hamstring tendon tibial insertion at up to 2 years...

Background and aims: Using free quadriceps tendon graft for anterior cruciate ligament (ACL) reconstruction has become more popular in the last years due to the low morbidity at the harvest site and biomechanical and structural properties similar to other types of graft (hamstring and patellar tendons). As long as the tibial tunnel fixation with interference screws is considered the standard fixation, femoral fixation is still an open subject. Even though the most common type of femoral tunnel fixation are the cortical suspension devices, the type of suture used for tying the graft to the loop is still evaluated and discussed...

The anterior cruciate ligament (ACL) rupture is a common disease that accounts for 250,000 cases/year in the United States. The anterolateral ligament (ALL) has been suggested to be an important restraint for rotational instability, and its reconstruction provides a reinforcement to the ACL reconstruction in this aspect, especially in high-demand athletes and in knees with high-grade pivot shift. Different techniques for associated ACL and ALL reconstruction have been described, but the ideal technique remains unclear...

Hamstring autografts in anterior cruciate ligament reconstruction have an excellent clinical track record, but some patients have hamstring tendons that yield grafts of smaller diameter, which has been shown to be a significant risk factor for worse outcomes and graft failure. Some authors have advocated augmentation with allograft in these patients. Tripling the semitendinosus yields a completely autogenous 5-strand graft with a larger diameter but still of sufficient length. In addition, imaging studies still show signal heterogeneity within grafts, even autografts, after the healing process, which correlates with worse biomechanical properties...

The anterior cruciate ligament suture augmentation technique is a method to augment anterior cruciate ligament reconstruction (ACLR) with autologous hamstring tendons using a braided ultrahigh-molecular weight polyester or polyethylene suture or suture tape and fixed on both the femoral and tibial sides independent of the graft to act as a backup or secondary stabilizer until complete integration and ligamentization of the graft take place. The technique is proposed to allow early rehabilitation and return to sports after ACLR and may be advantageous in patients with a high body mass index and in cases with small grafts (7 or 7...

After beginning with a search of more than 809 titles and ending up with 5 randomized controlled trials and 2 prospective comparative trials, the authors of a recent systematic review discovered that a statistically significant but nonclinical difference existed between anterior cruciate ligament reconstructions performed using a hamstring graft with either cross-pin or interference screw femoral fixation.

Safety belt, or cerclage, reinforcement of anterior cruciate ligament (ACL) grafts may protect against various modes of failure including creep and irreversible stretch, traumatic tearing, and slippage of the tendon-bone interface. A time-zero, biomechanical study shows that suture reinforcement may protect small and vulnerable hamstring ACL reconstruction grafts from these various modes of failure. Thus, in vivo comparative outcome analysis is indicated to determine if the benefits of reinforcement translate from the benchtop to the operating room...

Background: The aim of this study is to evaluate a possible correlation between specific anthropometric parameters and sizes of knee tendons commonly used for ACL reconstruction. We hypothesized that specific clinical and radiological knee measurements could be better tendon sizes predictors than age, gender, height and weight. Materials and methods: 100 consecutive patients were enrolled and 77 patients met the inclusion criteria of the study. All patients underwent a MRI of the knee with a 1...

Background: It remains unclear whether the tibiofemoral relationship in the sagittal plane is restored after anatomic anterior cruciate ligament (ACL) reconstruction, particularly in cases of chronic ACL deficiency (ACLD). Hypothesis: Patients with long-term ACLD will exhibit an anteriorly subluxed tibia both preoperatively and immediately postoperatively, even after anatomic reconstruction. Study Design: Cohort study; Level of evidence, 2...

BACKGROUND: Anterior cruciate ligament (ACL) reconstruction, using hamstring auto-graft is a common surgical procedure, which often leads to persistent hamstring muscle-strength deficiency and reduced function. The purpose of this randomized controlled trial (RCT) is to investigate the effect of a combined, progressive, strength and neuromuscular exercise intervention on knee muscle strength, functional capacity and hamstring muscle-tendon morphology in ACL-reconstructed patients with persistent hamstring muscle-strength deficiency compared with controls...

Hamstring tendon autograft remains a popular graft choice for anterior cruciate ligament (ACL) reconstruction. Although there are a variety of autograft and allograft options available for ACL reconstruction, advantages of hamstring tendon autografts include decreased postoperative knee pain and an overall easier surgical recovery compared with bone patellar tendon bone autograft. In addition, 4-stranded (quadruple) hamstring grafts are among the strongest grafts biomechanically (at time equals zero). Although the technique of hamstring autograft harvest is relatively straightforward, it is critical to pay attention to several technical steps to avoid iatrogenic neurovascular damage as well as to avoid premature amputation of the graft while using a tendon stripper...

Despite the popularity of anterior cruciate ligament (ACL) reconstruction procedures, the ideal graft for reconstruction remains a matter of controversy. The ideal graft for ACL reconstruction should have histologic and biomechanical characteristics similar to those of the native ACL; should be quickly and fully incorporated within the bony tunnels; should maintain its viscoelastic properties for a long time; should have minimal donor-site morbidity; should be of sufficient length and diameter; should have minimal adverse effects on the extensor mechanism; should have no risk of rejection or disease transmission; and should be cost-effective and readily available...
