Filter by:Different musculoskeletal conditions affect people all over the world and were considered by the WHO to be the leading cause of disability in 4 out of 6 regions in 2017, with an increase in the associated burden and impact on society expected in the coming years. The knee is a complex joint, vulnerable to various types of injury. The most common are ligament, meniscus and cartilage injuries of different etiologies. After surgery, as a result of the reflex inhibition of motor neurons and immobilization, there is rapid atrophy and weakness in the different associated muscles, affecting proprioception, muscle strength and extension, clearly compromising health-related quality of life. Through partnership and collaboration between health institutions and academia, the rehabilitation program will take place on an outpatient basis in a supervised manner, allowing its effectiveness to be assessed using Patient-Reported Outcome Measures. These instruments are a rapidly developing topic and it is essential to understand whether the Patient-Reported Outcome Measures used are sufficient to measure the results perceived by patients with lower limb pathology who take part in rehabilitation programs. The different Patient-Reported Outcome Measures will be applied before and after the program.
The ability to perform a cognitive task while walking simultaneously is essential in real daily life. However, the psychometric properties of dual-task walking tests have not been well established in patients undergoing total knee arthroplasty (TKA). The aim of study assess the test-retest reliability and validity of dual conditions TUG, 3MBWT, 8FWT nad 4SST in patients with TKA.
Purpose of the study is to investigate the effects of the criterion rehabilitation protocol versus accelerated rehabilitation protocol on the biomechanical determinants of the quality of performance and risk of reinjury.
Six cadaveric lower limbs will have PSI slope-reducing MOWHTO performed on and accuraccy of biplanar correction will be assessed.
The large number of studies in the recent decade dealing with knee injury prevention seems not effective enough to cause a decline in knee injury rates. Thus, it has been proposed to use non-linear mathematical models that simulate the operation of complex and dynamic systems. The present study aims to analyze the dynamic relationships of the risk factors for knee injuries through system dynamics modeling to effectively predict and prevent knee injury. The first part of this project includes a qualitative study informing the theoretical non-linear interrelationships among the risk factors. The aim is to examine the initial hypothetical model formulated in the first part of the project through statistical analysis such as factor analysis and structural equation modeling. Pre-season and in-season data from questionnaires and biomechanical measurements for risk factors will be collected from at least 100 athletes who participate in high-risk sports. The athletes will be monitored for injuries during one season, and these data will be used in the next part of the research plan. The next part of the project aims to develop a dynamic simulation model for predicting knee injuries using specific equations. The function of the simulation model will predict the propensity of knee injuries over time. The next step includes the validation and calibration of the model based on the knee injuries that occurred during the season. The validated and calibrated model will then provide implications for effective policy decisions in knee injury prevention.
This study will determine the safety and efficacy of using blood-flow restriction exercise enhancement (B-FREE) to overcome persistent quadriceps muscle weakness that occurs following a total knee replacement (TKR).
This observational study seeks to identify and validate novel soluble biomarkers (within blood, synovial fluid, urine) which contribute to the prognostic assessment of an individual with an acute knee injury, a group of individuals in which ~50% will progress to symptomatic radiographic knee osteoarthritis (OA). 150 individuals will be followed over 5 years with clinical assessment including validated questionnaires, biological sampling and radiological imaging (X ray, magnetic resonance imaging (MRI)).
The purpose of this study is to evaluate the long-term relief of pain and return to function for patients receiving DeNovo NT for cartilage lesions in the knee. DeNovo NT is a marketed product and has been used in more than 7,500 patients over the last 7 years.
The overall goal of this project is to reduce the risk for anterior cruciate ligament injuries by designing a targeted intervention that will alter the known kinematic and kinetic risk factors associated with ACL injuries. This study will address the following specific aims: 1) To optimize a wearable, targeted, active training feedback device to reduce the risk of ACL injury among healthy subjects by inducing patterns of movement that alter the known kinematic and kinetic risk factors associated with ACL injuries. 2) To evaluate the efficacy of the active device and determine if the device reduces the risk of ACL injury among healthy subjects by effectively inducing patterns of movement that alter the known kinematic and kinetic risk factors associated with ACL injuries.
The SeriACL device was developed as an alternative to an autograft (i.e., tissue that is taken from a patient's own body) or an allograft (i.e., tissue that is taken from a cadaver) for ACL reconstruction. The SeriACL device is made of silk yarns, knit and processed with SeriCoat™ surface treatment which makes it easier to wet the material. The SeriACL device is designed to be a temporary support structure to replace the torn ACL and to stabilize the knee joint following surgical repair. It is designed to use the body's own healing process to regenerate the patient's own new ligament tissue. As the new tissue grows and the support structure is needed less over time, the SeriACL device is bioresorbed (i.e., broken down) by the patient's body. The SeriACL device is designed to be installed with standard surgical techniques for ACL repair. This study is designed to test the safety of the SeriACL device in primary total ACL repair in patients with a torn ACL. The study will evaluate whether repair of the ACL with the SeriACL device will return the knee to normal function and what, if any, side effects will occur.
