assessment anterior cross ligament

BACKGROUND: An elevated posterior tibial slope (PTS) is associated with an increased risk for anterior cruciate ligament and meniscal injury. Recent evidence suggests that the PTS is elevated in patients with Osgood-Schlatter disease. PURPOSE: To determine whether there is an association between objective measures of anterior tibial tubercle growth and PTS. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: A total of 100 radiographs were randomly selected from a sample of patients who had received a lateral knee radiograph that captured at least 15 cm of the tibia distal to the knee joint line at a single institution between December 2020 and March 2022...

BACKGROUND: Rectangular tunnel and graft have been recently designed to closely resemble the native anatomy in anterior cruciate ligament reconstruction (ACLR). This study was performed to compare the short-term clinical outcomes between rectangular and round femoral tunnels in ACLR using quadriceps tendon-patellar bone (QTPB) autografts. METHODS: A total of 78 patients who underwent primary ACLR with QTPB autografts performed by three senior surgeons and had at least 1 year of postoperative follow-up were retrospectively reviewed...

BACKGROUND: Studies on the changes of extracellular matrix (ECM) in pelvic organ prolapse (POP) are still controversial. OBJECTIVE: To identify the changes in the ECM in POP patients. SEARCH STRATEGY: Comprehensive searching in Embase, PubMed, Web of Science and the Cochrane Library was carried out until 23 February 2023. SELECTION CRITERIA: Studies comparing the protein levels of ECM-related components between women with and without POP...

BACKGROUND: The success of anterior cruciate ligament (ACL) reconstruction relies on the accurate replication of the native ACL anatomy, including attachment shapes. The tibial attachment of the ACL exhibits significant shape variations with elliptical, C, and triangular shapes, highlighting the need for objective classification methods and additional information to identify individual anatomic variations. HYPOTHESIS: The location of the attachment of the anterior horn of the lateral meniscus (AHLM) may determine the shape of the ACL attachment...

OBJECTIVES: To assess the proportion and pattern of injury of the anterolateral ligament (ALL) and the Kaplan fibre (KF) complex in knees with anterior cruciate ligament (ACL) injuries on MRI using three-dimensional (3D) proton density (PD) sequences. METHODS: A total of 88 patients having ACL injury were included in this cross-sectional study. 3D PD sequences were used to assess injury of ALL and the KF complex and were graded on a scale of 0 to 3. MR images were evaluated by two radiologists...

BACKGROUND: Endurance capability in the muscles controlling the knee is poorly understood post anterior cruciate ligament (ACL) reconstruction, despite many sporting activities requiring notable muscle endurance. The hamstring muscles, when active, provide important anatomical support to protect the reconstructed graft. In the absence of good hamstring endurance, fatigue may predispose individuals to re-injury. OBJECTIVE: To assess whether ACL reconstruction (ACLR) with a hamstring graft leads to reduced hamstring endurance 9-13 months post-surgery...

BACKGROUND: Adolescents present a high incidence of ACL injury compared with other age groups. Examining the risk factors that predispose adolescents to primary noncontact ACL injury is a key strategy to decrease the number of injuries in this population. OBJECTIVE: The aim of this systematic review was to summarise the existing literature investigating extrinsic risk factors that have been linked with primary noncontact ACL injury risk (identified either using ACL injury occurrence or using screening tests measuring biomechanical mechanisms for noncontact ACL injury) in adolescents including research investigating: (1) the association between extrinsic risk factors and primary noncontact ACL injury risk; and (2) whether primary noncontact ACL injury risk was different in populations or groups exposed to different extrinsic risk factors in adolescents...

PURPOSE: The aim of this study is to assess the dynamics of the tear site of meniscal ramp lesions, particularly considering knee flexion angles, and validate anchor fixation using an all-inside device. METHODS: Eight Thiel-embalmed paired cadaveric knees with their whole bodies were used in this study. The ramp lesions were created arthroscopically, and ramp lesion dynamics were evaluated by gradually extending the knee from 90° of knee flexion. Changes in the gap and step-off (0: no step-off; 1: cross-sectional overlap exists; and 2: tibial articular surface exposed) were evaluated at 90°, 60°, 30°, and 10° of knee flexion...

OBJECTIVES: The objective of this study was to assess the mid-term effectiveness of a return to sport (RTS) test in relation to preventing anterior cruciate ligament (ACL) re-rupture and contralateral ACL injury following ACL reconstruction (ACLR). Furthermore, this study aimed to assess the timing of passing a, RTS-test after surgery, and the effect age has on RTS outcomes. METHODS: Patients undergoing ACLR between August 2014 and December 2018 took an RTS-test following rehabilitation...

BACKGROUND: It is unknown whether knee flexor strength recovers after anterior cruciate ligament (ACL) reconstruction with a hamstring tendon (HT) autograft and whether persistent knee flexor strength asymmetry is associated to a second ACL injury. OBJECTIVE: We aimed to systematically review (1) whether knee flexor strength recovers after ACL reconstruction with HT autografts, and (2) whether it influences the association with a second ACL injury. A third aim was to summarize the methodology used to assess knee flexor strength...

CONTEXT: The purpose of this study was to compare short-term clinical outcomes between meniscus procedures performed with anterior cruciate ligament reconstruction (ACLR), ACLR (ACLR-only), ACLR with meniscectomy/resection (ACLR-resect), and ACLR with meniscal repair (ACLR-repair) for bone patellar tendon bone grafts (BPTB) and hamstring tendon grafts, separately. DESIGN: This was a cross-sectional study conducted in a controlled laboratory setting as part of a large point-of-care collaborative research program...

BACKGROUND: Arthrogenic muscle inhibition (AMI) is a process in which neural inhibition after injury or surgery to the knee results in quadriceps activation failure and knee extension deficit. PURPOSE: To determine the incidence and spectrum of the severity of AMI after acute anterior cruciate ligament (ACL) injury using the Sonnery-Cottet classification, to determine the interobserver reliability of the classification system, and to investigate potential important factors associated with AMI after ACL injury...

BACKGROUND: Quadriceps strength testing is recommended to guide rehabilitation and mitigate the risk of second injury following anterior cruciate ligament (ACL) reconstruction. Hand-held dynamometry is a practical alternative to electromechanical dynamometry but demonstrates insufficient reliability and criterion validity in healthy and ACL-reconstructed participants respectively. The purpose of this study is to investigate the reliability and concurrent validity of inline dynamometry for measuring quadriceps strength...

BACKGROUND: The objective of this study was to summarize available literature that explored the impact of body mass index (BMI) on physical activity participation among individuals who were subjected to the anterior cruciate ligament reconstruction (ACLR). METHODS: A total of three electronic databases, including Web of Science, Scopus, and PubMed, were comprehensively searched to identify relevant investigations. The following inclusion criteria were applied: (1) study design was observational; (2) participants underwent the ACLR; (3) BMI was estimated as a predictor variable; and (4) outcomes evaluated referred to physical activity...

CONTEXT: With the high prevalence of anterior cruciate ligament rupture among young and active individuals, rehabilitation after the injury and surgery should meet the current evidence-based recommendations to restore knee function and reduce the risk of further injury. This study aimed to investigate the current rehabilitation practices and return to sports (RTS) criteria after anterior cruciate ligament reconstruction (ACLR) among physical therapists in Saudi Arabia. DESIGN: Online cross-sectional survey-based study...

CONTEXT: Poor psychological responses after anterior cruciate ligament reconstruction (ACLR) have been associated with a failure to return to sport and increased secondary injury risk. However, we do not know whether poor psychological responses after ACLR influence patient-reported knee function and knee symptoms. OBJECTIVE: To examine the association between psychological factors (ie, psychological readiness and injury-related fear) and the presence of persistent knee symptoms in individuals 6 to 12 months after ACLR...

INTRODUCTION: Pelvic Organ Prolapse is the descent of one or more of the anterior vaginal wall, posterior vaginal wall, the uterus, or the apex of the vagina. Surgical intervention addresses both anatomical defect and associated symptoms. The landscape of prolapse surgery has been evolving constantly over years. Emerging evidences either support or challenge existing surgical treatment options, making urogynecology a dynamic field. In Ethiopia, the surgical management of pelvic organ prolapse has transitioned from abdominal to vaginal hysterectomy, supplemented later by McCall's culdoplasty...

BACKGROUND: Quadriceps tendon soft tissue autograft represents an increasingly popular graft option for anterior cruciate ligament reconstruction (ACLR), particularly for adolescents, some of whom have an open physis, precluding use of graft options with bone plugs. PURPOSE/HYPOTHESIS: The purpose of this study was to quantify return-to-sport performance assessments in adolescents at 6 months after ACLR with all-soft tissue quadriceps tendon autograft (ACLR-Q) versus hamstring tendon autograft (ACLR-HS)...

OBJECTIVES: To investigate current clinical practice of Swiss physiotherapists treating patients with anterior cruciate ligament reconstruction (ACLR) from pre-operative rehabilitation until return to sport (RTS). We assessed optimisation strategies in daily practice and the perceived barriers to these optimisations, and evaluated whether there was a relevant difference in clinical practice for physiotherapists with post-graduate certification in sports physiotherapy or deep clinical experience and those without such experience...

CONTEXT: Decreased trunk neuromuscular control is a risk factor for both upper- and lower-extremity injuries, yet there are few reliable and valid clinical tests to identify deficits. OBJECTIVE: The purpose of this study was to determine the reliability and known-groups validity of a novel clinical test, the seated trunk control test (STCT). DESIGN: Cross-sectional reliability and known-groups validity study. SETTING: Laboratory...
