Active clinical trials for "Anterior Cruciate Ligament Injuries"

Knees injuries commonly affect the ACL. French current methodology is based on MRI focused on the knee with morphological sequences (T1, DP fat sat) allowing the study of ACL as follows: No lesion / Partial tear / Complete tear. The treatment (kinesitherapy, surgery, no intervention) is defined taking into account several factors such as age, knee laxity, physical activity and outcome of the radiology analysis (partial or complete tear). However, if the classification is straightforward in case of complete tear, it is not possible to establish a quantitative impact on the ACL in case of partial tear. As a consequence, the investigators will analyze the anisotropy coefficient with diffusion tractography. Any patient who undergo a posttraumatic knee MRI at the CHU Amiens Picardie will have an appointment at the 3T "Signa" MRI that has the knee-centric diffusion tractography sequence.

Anterior cruciate ligament (ACL) injury constitutes the largest problem in female elite ball/team sport today, due to its relatively high incidence and serious short- and long-term consequences. Especially in handball, these injuries typically occur in actions that are essential for the game, i.e. landings and cutting maneuvers, imposing a challenge for risk reduction strategies. Although knowledge about risk factors is constantly increasing and ACL injury prevention programs have been successful in reducing injuries in rigorous scientific study settings, the real-world injury incidence remains high, and even continues to increase. The purpose of this explorative intervention study is to assess the effect of an eight-week strength and technique training in female handball players and its influence on ACL-specific risk factors, especially knee abduction moment (KAM). The results are compared with a control group that did not do the specially designed technique/muscle training.

There is no consensus regarding the best surgical management of primary ACL tears. Recent evidence suggests that internal brace augmentation may increase load failure and therefore stabilize the graft in-situ at the time of ACL reconstruction. This prospective randomized controlled trial aims to compare the time to return to activity, and participant reported outcomes in participants with bone-tendon-bone ACL reconstruction with and without (control) internal brace augmentation.

The present experimental study aims to evaluate the effectiveness and tolerability of isoinertial strength training of the hamstrings using machines in patients with ACL-R during the intermediate post-intervention phases.

The purpose of this study is to investigate the association between time spent in moderate to vigorous physical activity and markers of cartilage metabolism in the years following anterior cruciate ligament reconstruction.

The purpose with this present study is to investigate the effect og a non-surgical regime in patients with an Anterior Cruciate ligament injury. The effect will be measured by patient reported outcome scores, level of function and how many of the patients are converting to operative treatment.

Decathlon has developed kneeMID500-STRONG700 products which are two medical devices designed to be used for sport resumption after mild (kneeMID500) or moderate (KneeSTRONG100) knee sprain or after an Anterior Cruciate Ligament surgery. The difference between these devices is based on the strength of compression and the knee maintain. The objective of this multicentre study is to collect data on the related clinical complications and clinical outcomes of market-approved Decathlon kneeMID500-STRONG700 products to demonstrate safety and performance of these devices in a real-world setting.

EXECUTIVE SUMMARY Research Title An Android Application-Based Delivery of Guided Rehabilitation After Anterior Cruciate Ligament Reconstruction: A Randomised Single-Blinded Pilot Study Investigators Principle Investigator (Supervisor) : Prof Madya Dr Mohd Nizlan Mohd Nasir Co-investigator (Supervisor) : Dr Khairil Anwar bin Ahmad Hanif Dr Firdati binti Mohamed Saaid Co-Investigator (Student) : Dr Tan Eng Kee Background Anterior cruciate ligament injuries are a common and significant injury seen in active persons. This injury can adversely affect the patient's daily life, as well as delay or prevent return to sports, in addition to predisposing patients to long-tern knee conditions such as osteoarthritis. Despite surgical advances, ACL reconstruction surgery outcomes are still considered poor, with a low as 55% of patients returning to active sports. One of the key factors that lead to a poorer outcome is the patient's compliance to rehabilitation, causing less than satisfactory results in the post-operative period. With the conventional regime, rehabilitation typically takes one year. Patients tend to drop out of the rehabilitation regime due to its long duration. In order to combat this, the accelerated regime was developed and only took 6 months. This regime has been researched and validated by numerous international publications since its inception. However, compliance remained poor. Purpose of Study The study aims to assess the feasibility and effectiveness of a smartphone-based application to guide the patient's rehabilitation regime and improve compliance. Data Gathering and Analysis Data for outcome assessment will be obtained via a patient administered questionnaire called the Knee Injury and Osteoarthritis Outcome Score (KOOS). This scoring system is available for free without licensing requirements, and has been validated by numerous research publications internationally. Analysis of obtained data will be performed using SPSS version 22. Continuous data will be displayed as mean + SD as well as median. Conclusion There is a need for a new method of information provision as the country moves towards the age of information technology. This smartphone-based application for guided rehabilitation will be an innovative new method to aid patients. Lastly, the researchers would like to thank the members of JKEUPM for their time, effort and kind consideration of this research proposal.

Atrophy and weakness are ubiquitous after a ACL rupture and associated with a worsened long-term recovery of individual capacities, despite surgery and rehabilitation. Preoperative rehabilitation (prehab) is believed to prepare patients for surgery and post-operative rehabilitation. However, prehab programs are highly variable, and do not always aim to develop/maintain neuromuscular parameters. The purpose of this study is to assess the effects of a lower limb strengthening training program during prehab prior to ACL Surgery on lower limb structure and function.

The aim of this study is to investigate how hormonal contraceptives affect ACL rupture incidence within menstrual cycle phases. It is thought hormones such as estrogen and progesterone (which fluctuate throughout the normal menstrual cycle) play a role in the laxity of ligaments within the body. It is hypothesised that around the time of ovulation the ACL undergoes increased laxity, leaving it more likely to be injured. This study will look at the phase of the menstrual cycle in which the ACL injuries occur and whether there are differences due to the use and type of hormonal contraception participants may be using (such as Combined oral contraceptive, Mirena, Implanon), which can modify the levels of circulating estrogen and progesterone. This study involves participants completing an anonymous electronic survey after presenting to a sports or orthopaedic clinic with an ACL rupture. The survey collects information about participant's current ACL injury and any previous knee injuries; typical menstrual cycle patterns and the use of hormonal contraception; and history of sports participation. Responses will be analysed to look for similarities and differences in ACL injury occurrence by menstrual cycle phase and hormonal contraceptive use. The study hypotheses are: Hormonal contraceptives that are known to reduce ovulatory rises in estrogen will have the most consistent pattern of ACL rupture incidence across all phases of the menstrual cycle. There will be a mitigated risk of ACL rupture in the preovulatory phase of the menstrual cycle, relative to the other phases, in women using hormonal contraception compared to those not using hormonal contraception There will be a higher proportion of ACL ruptures during the preovulatory phase of the menstrual cycle in non-hormonal contraceptive users.
