PURPOSE: To investigate whether an increased magnitude of quantitative rotatory knee laxity is associated with a greater level of generalized joint laxity in ACL-injured and contralateral knees. METHODS: A total of 103 patients were enrolled across four international centers to undergo anatomic ACL reconstruction. Rotatory knee laxity was evaluated preoperatively, both in the awake state and under anesthesia, using the standardized pivot shift test. Two devices were used to quantify rotatory knee laxity; an inertial sensor, measuring the joint acceleration, and an image analysis system, measuring the lateral compartment translation of the tibia...

Both, hamstring and ACL injuries are among the most typical injuries, particularly in change of direction and high speed running sports. They're also difficult to treat. Therefore, in the past few years, sports medicine practitioners and exercise scientists have mainly been focusing on the development and implementation of preventive programs in order to reduce the number of lower limb injuries, mainly by improving knee alignment. A number of studies have been able to prove the success of these training interventions, which are mainly addressing sensorimotor abilities and plyometric activities...

INTRODUCTION: According to Fraser's description, ipsilateral femoral and tibial diaphyseal fractures are characterised as type I floating knee and have a better prognosis than fractures with joint involvement (type II). There are few reports of functional and muscle strength in these patients. The objective of this study was to evaluate the functional and isokinetic muscle strength of patients with type I floating knee undergoing femoral and tibial internal fixation. METHODS: Patients with type I floating knee undergoing concomitant femoral and tibial internal fixation were invited for clinical evaluation...

The most common events during which anterior cruciate ligament (ACL) injuries occur in football are pressing situations. This study aimed to describe the knee and hip joint kinematics during pressing situations in football games in order to identify kinematic patterns in actions with a high risk for ACL injuries. We filmed 5 female collegiate football matches and identified 66 pressing situations. Five situations with a large distance between the trunk and foot placements in the sagittal plane were analysed using a model-based image-matching technique...

PURPOSE: To compare the results of bone-patellar tendon-bone graft (BPTB), semitendinosus-gracilis graft with preserved insertions (STGPI) and semitendinosus-gracilis-free graft (STGF) in terms of graft failure, objective mechanical stability, functional outcome, and return to sports in elite and recreational sports persons. It was hypothesized that the STGPI graft provided superior outcome as compared to the other two grafts. METHODS: Two hundred and forty-nine elite and recreational players who underwent ACL reconstruction surgery, with BPTB graft (N = 80), STGPI graft (N = 85), and STGF graft (N = 84) with a minimum follow-up of 2 years, were assessed using clinical tests, knee arthrometer (KT 1000™), single-leg hop test, Lysholm knee score, Tegner's activity scale, and return to sports...

BACKGROUND: Current studies demonstrate encouraging short-term results after primary anterior cruciate ligament (ACL) suture anchor repair. However, earlier studies reported deterioration of knee function at 5-year follow-up following good clinical short-term recovery. Therefore, the aim of this study was to evaluate clinical long-term results after primary ACL repair at a minimum 5-year follow-up. METHODS: In a retrospective study, 13 patients were included between 2009 and 2012...

Anterior cruciate ligament (ACL) injuries in basketball appear to be more common when players are in possession of the ball. The greater risk of ACL injury when in possession of the ball may result from the athlete's inability to fully attend to their movement. However, it is also possible that having to carry/manipulate the ball restricts the athlete's ability to utilise their upper extremities for stability during a manoeuvre. The purpose of this study was to explore how possession of a basketball and divided attention influence lower extremity mechanics during cutting and landing...

PURPOSE: A deep lateral femoral notch (LFN) on lateral radiographs is indicative of ACL injury. Prior studies have suggested that a deep LFN may also be a sign of persistent rotatory instability and a concomitant lateral meniscus tear. Therefore, the purpose of this study was to evaluate the relationship between LFN depth and both quantitative measures of rotatory knee instability and the incidence of lateral meniscus tears. It was hypothesized that greater LFN depth would be correlated with increased rotatory instability, quantified by lateral compartment translation and tibial acceleration during a quantitative pivot shift test, and incidence of lateral meniscus tears...

PURPOSE: Knee ligamentous trauma and the following pain is one of the most prevalent athletic injuries. Transcutaneous electrical nerve stimulation is one of the conservative approaches in controlling pain which is low cost, noninvasive, and safe with low complications. Our purpose was to study whether transcutaneous electrical nerve stimulation (TENS) could help athletes perform better during the first phase of rehabilitation (0-4 weeks) after anterior cruciate ligament (ACL) reconstruction surgery and until the follow-up...

Traumatic knee injuries often result in damage to articular cartilage and other joint structures. Such trauma is a strong risk factor for the future development and progression of osteoarthritis (OA). The molecular mechanisms and signaling pathways modulating response to knee joint trauma remain unclear. Moreover, investigations of biomarkers influencing responses have been targeted rather than broad, unbiased discovery studies. Herein we characterize the complete complement of extracellular RNA (exRNA) in the synovial fluid of 14 subjects following knee injury...
