BACKGROUND: To characterize the mechanism of knee injuries among NBA players during the 2010-2020 seasons using video-based analysis. METHODS: An injury database of NBA players was queried for knee injuries from the 2006-07 to 2020-21 seasons and cross-referenced with NBA injury reports. Youtube.com was searched to identify available injury footage. The mechanism of knee injury during play was analyzed by three independent reviewers. Non-mechanistic data related to the injury was gathered from news reports and official NBA websites...

INTRODUCTION: Tibial eminence fractures resulting from the avulsion of the anterior cruciate ligament (ACL) insertion are a common knee injury in the pediatric population. This injury is traditionally corrected through internal fixation using a guide pin and a cannulated screw. Due to the reported consequences of cannulated screws impinging on the joint space, we explored an alternative procedure to address this injury without the use of cannulated screws. We believe this is the first report of an alternate and improved procedure for repairing a tibial eminence fracture caused by ACL avulsion using non-absorbable sutures to secure the bony fragment back onto the tibial eminence...

INTRODUCTION: The study discussed three patients who experienced both anterior cruciate ligament (ACL) injury and patellofemoral instability. This combination of injuries is rare and has a scarcity of published /literature. The study described the mechanism of injury, diagnostic modalities, and the decision-making process for surgical intervention. It emphasizes the importance of a comprehensive clinical evaluation and discusses surgical techniques for combined ACL and medial patellofemoral ligament (MPFL) reconstruction...

INTRODUCTION: People with post-polio syndrome usually have some residual deformities. Genu recurvatum is very commonly seen in such cases which are a risk factor for anterior cruciate ligament (ACL) injury due to the altered biomechanics. To the best of our knowledge, this is the first report in literature presenting ACL reconstruction in a limb with genu recurvatum deformity treated with supracondylar osteotomy. CASE REPORT: A 49-year-old female with genu recurvatum and history of polio presented with pain and instability...

INTRODUCTION: Simultaneous anterior cruciate ligament (ACL) and ipsilateral hamstring ruptures have never been reported in the literature. The purpose of this article is to describe a treatment approach for such a case. The principles in this case can help guide treatment for any patient with concomitant ACL and hamstring pathology. CASE REPORT: We describe the case of a 53-year-old male who presented with left ipsilateral simultaneous complete proximal hamstring tendon (HT) and ACL tears after an acute tennis injury...

BACKGROUND: Stress radiography is a viable imaging modality that can also be used to assess the integrity of the anterior cruciate ligament (ACL) after primary or secondary injury. Because conventional radiography is relatively easy, affordable, and available worldwide, the diagnostic efficacy of ACL standing, lateral decubitus, and supine stress radiography should be evaluated. PURPOSE: To examine the existing literature regarding the application of stress radiography in evaluating the integrity of the ACL...

BACKGROUND: Anterior cruciate ligament reconstruction (ACLR) is a common procedure for symptomatic ACL injuries. Age is often factored into clinical decision making and can influence the choice of conservative management over surgical intervention. The aim of this study was to investigate the effect of chronological age on the clinical outcome following ACLR. METHOD: Six validated patient-reported outcome measures (PROM) were used to collect pre-operative and post-operative scores from patients with ACL rupture undergoing ACLR...

INTRODUCTION: Anterior cruciate ligament (ACL) injuries in young, active patients generally require ACL reconstruction (ACLR) in order to restore mechanical and postural stability. The fear of movement or reinjury (kinesiophobia) has become increasingly recognized in the post-ACLR population, however the association between restoration of postural stability and kinesiophobia remains largely unknown. The purpose of this study was to investigate changes in mean TSK-11, DMA scores and time on the testing platform, as well as any correlation between TSK-11 and mean overall and individual translational and rotational DMA scores during the first 12 months following ACLR...

INTRODUCTION: Revision Anterior cruciate ligament reconstruction (ACLR) is a challenging surgery occurring in 3-24% of primary reconstructions. A meticulous planning to study the precise size and location of both femoral and tibial bone tunnels is mandatory. The aim of the study was to evaluate the intra- and inter-operator differences in the decision-making process between experienced surgeons after they were asked to make pre-operative planning for ACL revision reconstruction with the use of both the CT scan and a 3D printed model of the knee...

(1) Background: The aim of this study was to investigate how a medial meniscus injury accompanying an anterior cruciate ligament rupture affects the clinical outcome 10 years after ACL reconstruction. (2) Methods: A total of 37 patients who received anterior cruciate ligament reconstruction (ACLR) were included in this retrospective study. Two groups were analyzed at a single follow-up of 10 years: (i) "isolated (ACLR)" ( n = 20) and (ii) "ACLR with medial meniscal injury" ( n = 17). The following clinical scores were recorded: International Knee Documentation Committee (IKDC), the Knee Injury and Osteoarthritis Outcome Score (KOOS), Lysholm Score and Tegner Activity Score...

BACKGROUND: The etiopathogenesis of ACL rupture is not clarified. The aim of this study is to identify genomic regions and genetic variants relevant to anterior cruciate ligament injury susceptibility that could be involved in non-contact anterior cruciate ligament ruptures. METHODS: A systematic review of the literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines with a PRISMA checklist and algorithm...

Background: After the increasingly common anterior cruciate ligament reconstruction (ACLR) procedure in competitive athletes, rehabilitation is crucial for facilitating a timely return to sports (RTS) and preventing re-injury. This pilot study investigates the patient-reported outcomes of postoperative rehabilitation in competitive athletes, comparing supervised rehabilitation (SVR) and home-based rehabilitation (HBR). Methods: After ACLR, 60 (out of 74 screened) athletes were recruited and equally divided into HBR and SVR groups using non-probability convenience sampling, with each group comprising 15 males and 15 females...

Currently, medical imaging has largely supplanted traditional methods in the realm of diagnosis and treatment planning. This shift is primarily attributable to the non-invasive nature, rapidity, and user-friendliness of medical-imaging techniques. The widespread adoption of medical imaging, however, has shifted the bottleneck to healthcare professionals who must analyze each case post-image acquisition. This process is characterized by its sluggishness and subjectivity, making it susceptible to errors. The anterior cruciate ligament (ACL), a frequently injured knee ligament, predominantly affects a youthful and sports-active demographic...

(1) Background: The purpose of this systematic review was to determine the prevalence of bone bruises in patients with anterior cruciate ligament (ACL) injuries and the location of the bruises relative to the tibia and femur. Understanding the relative positions of these bone bruises could enhance our comprehension of the knee loading patterns that occur during an ACL injury. (2) Methods: The MEDLINE, EMBASE, and the Cochrane Library databases were searched for studies that evaluated the presence of bone bruises following ACL injuries...

BACKGROUND: Female athletes are four to six times more likely to sustain an anterior cruciate ligament (ACL) injury than male athletes. Jump-landing biomechanics are influenced by maturation, with post-pubertal female athletes at a heightened risk of ACL injuries. OBJECTIVE: The aim of our systematic review was to identify and summarise the current evidence regarding the changes in kinematic and kinetic risk factors associated with ACL injuries during jump-landing tasks in female athletes at various stages of maturity...

PURPOSE: To assess children's physical function and subjective knee status 1 and 3 years after anterior cruciate ligament (ACL) reconstruction. It was hypothesised that there was no difference between the operated and normal legs in relation to physical strength and function, that there was <-2 mm side-to-side difference in knee laxity, and that the subjective knee function was better 3 years after ACL reconstruction compared to 1 year after. METHODS: Children (<16 years of age) who had an ACL reconstruction had follow-up with physical function tests (four hop tests and strength measurement in a power rig [PR]), anterior knee laxity (measured using a Rolimeter) and patient-reported outcome measures (Pedi-International Knee Documentation Committee [IKDC] and Knee injury and Osteoarthritis Outcome Score [KOOS]-Child) 1 and 3 years postoperatively...

PURPOSE: To systematically review studies utilizing video analyses to evaluate anterior cruciate ligament (ACL) injury mechanisms in athletes during sport to better understand risk factors and the potential for injury prevention. METHODS: A literature search was conducted in accordance with the 2020 PRISMA guidelines statement using SCOPUS, PubMed, Medline, and the Cochrane Central Register for Controlled Trials from database inception through June 2023. Inclusion criteria including studies reporting on ACL injury mechanisms occurring in athletes based on video analysis...

Enhancing sidestep cutting (SSC) execution in talented female soccer players: A four-week intervention program with video instruction. J Strength Cond Res XX(X): 000-000, 2024-Implicit learning has the potential to improve movement execution and reduce injury risk. Previous research showed beneficial effects of short-term interventions with implicit learning in male athletes. However, research on long-term interventions in female athletes is lacking...

Anterior cruciate ligament (ACL) tears are one of the most common orthopedic injuries among athletes. Although a small proportion of patients with isolated tears can return to sports after completing a nonsurgical rehabilitation program, ACL reconstruction is frequently recommended for young athletes, especially those with concomitant knee injuries or symptomatic knee instability. Alongside emerging evidence for the effect of prehabilitation, the current standard of care for postoperative ACL physical therapy includes pain control, range of motion, quadriceps strengthening, weight bearing, postoperative bracing, and dynamic limb stabilization and control...

Recent advancements in neuroimaging have illustrated that anterior cruciate ligament (ACL) injuries could impact the central nervous system (CNS), causing neuroplastic changes in the brain beyond the traditionally understood biomechanical consequences. While most of previous functional magnetic resonance imaging (fMRI) studies have focused on localized cortical activity changes post-injury, emerging research has suggested disruptions in functional connectivity across the brain. However, these prior investigations, albeit pioneering, have been constrained by two limitations: a reliance on small-sample participant cohorts, often limited to two to three patients, potentially limiting the generalizability of findings, and an adherence to region of interest based analysis, which may overlook broader network interactions...
