    BACKGROUND: Identifying risk factors for knee pain and anterior cruciate ligament (ACL) injury can be an important step in the injury prevention cycle.

    OBJECTIVE: We evaluated two unique prospective cohorts with similar populations and methodologies to compare the incidence rates and risk factors associated with patellofemoral pain (PFP) and ACL injury.

    METHODS: The 'PFP cohort' consisted of 240 middle and high school female athletes. They were evaluated by a physician and underwent ...

    INTRODUCTION: Arthrofibrosis is a known complication after anterior cruciate ligament (ACL) reconstruction. ACL reconstruction is being performed with increased frequency in the pediatric population. The purpose of this study was to determine the prevalence of arthrofibrosis in children and adolescents and to identify risk factors for arthrofibrosis.

    METHODS: The study design was a retrospective case series. Medical records for 1016 consecutive ACL reconstructions in patients aged 7 to ...

    BACKGROUND: Preclinical studies suggest that for complete midsubstance anterior cruciate ligament (ACL) injuries, a suture repair of the ACL augmented with a protein implant placed in the gap between the torn ends (bridge-enhanced ACL repair [BEAR]) may be a viable alternative to ACL reconstruction (ACLR).

    HYPOTHESIS: We hypothesized that patients treated with BEAR would have a noninferior patient-reported outcomes (International Knee Documentation Committee [IKDC] Subjective Score; ...

    BACKGROUND: Primary repair of the anterior cruciate ligament (ACL) augmented with a tissue engineered scaffold to facilitate ligament healing is a technique under development for patients with ACL injuries. The size (the amount of tissue) and signal intensity (the quality of tissue) of the healing ligament as visualized on magnetic resonance imaging (MRI) have been shown to be related to its strength in large animal models.

    HYPOTHESIS: Both modifiable and nonmodifiable risk factors could ...

    BACKGROUND: The quality of a repaired anterior cruciate ligament (ACL) or reconstructed graft is typically quantified in clinical studies by evaluating knee, lower extremity, or patient performance. However, magnetic resonance imaging of the healing ACL or graft may provide a more direct measure of tissue quality (ie, signal intensity) and quantity (ie, cross-sectional area).

    HYPOTHESES: (1) Average cross-sectional area or signal intensity of a healing ACL after bridge-enhanced ACL ...

    OBJECTIVE: Although stress fractures are a source of significant morbidity in active populations, particularly among young female athletes, the causes of stress fractures have not been explored among females <17 years of age or in the general population. The purpose of this study was to examine correlates of stress fractures in a large, population-based, national, cohort study of preadolescent and adolescent girls.

    METHODS: A cross-sectional analysis of data from 5461 girls, 11 to 17 ...

    BACKGROUND: The management of anterior cruciate ligament injuries in skeletally immature patients is controversial. Conventional adult reconstruction techniques risk potential iatrogenic growth disturbance due to physeal damage. The purpose of this study was to evaluate the results of a physeal sparing, combined intra-articular and extra-articular reconstruction technique in prepubescent skeletally immature children.

    METHODS: Between 1980 and 2002, forty-four skeletally immature ...

    BACKGROUND: Active spondylolysis is an acquired lesion in the pars interarticularis and is a common cause of low back pain in the young athlete.

    OBJECTIVES: To evaluate whether the one-legged hyperextension test can assist in the clinical detection of active spondylolysis and to determine whether magnetic resonance imaging (MRI) is equivalent to the clinical gold standard of bone scintigraphy and computed tomography in the radiological diagnosis of this condition.

    METHODS: A prospective ...

    BACKGROUND: Management of anterior cruciate ligament injuries in skeletally immature patients is controversial. Conventional surgical reconstruction techniques for adults can cause iatrogenic growth disturbance due to physeal damage in children. The purpose of this study was to evaluate the results of a transphyseal reconstruction technique in pubescent but skeletally immature adolescents.

    METHODS: Between 1996 and 2004, sixty-one knees in fifty-nine skeletally immature pubescent ...

    Imbalance of the internal and external rotator musculature of the shoulder, excess capsular laxity, and loss of capsular flexibility, have all been implicated as etiologic factors in glenohumeral instability and impingement syndrome; however, these assertions are based largely on qualitative clinical observations. In order to quantitatively define the requirements of adequate protective synergy of the internal and external rotator musculature, as well as the primary capsulolabral ...

    Hip arthroscopy has become an established procedure for certain indications in adults, but experience in children and adolescents has been more limited. The purpose of this study is to report the early-term results of hip arthroscopy in children and adolescents. A consecutive case series of 54 hip arthroscopies in 42 patients 18 years old and younger over a 3-year period at a tertiary-care children's hospital with a minimum of 1 year of follow-up was reviewed. Patients were assessed with ...

    OBJECTIVE: Determine the percentage of skeletally immature athletes returning to sports after anterior cruciate ligament (ACL) injury and reconstruction.

    DESIGN: Retrospective case series.

    SETTING: Boston Children's Hospital Division of Sports Medicine.

    PATIENTS: Eligible participants were identified by chart review. Males and females aged ≤14 year old who were greater than 2 years after ACL reconstruction surgery seen between January 2001 and May 2009. A total of 250 patients completed ...

    OBJECTIVE: The aim of this study was to determine key components in neuromuscular training that optimise ACL injury reduction in female athletes using meta-regression analyses.

    DESIGN: Systematic review and meta-regression.

    DATA SOURCES: The literature search was performed in PubMed and EBSCO.

    ELIGIBILITY CRITERIA: Inclusion criteria for the current analysis were: (1) documented the number of ACL injuries, (2) employed a neuromuscular training intervention that aimed to reduce ACL ...
