Filter by:The measurement of the patellar height is essential to decide and quantify the surgical correction to be made. The classic index is that of Cato and Deschamps. It has the advantage of its simplicity, with the measurement on a simple profile radiograph of the ratio between the distance from the patella to the tibia and the length of the patella. However, it has the disadvantage of measuring this height in relation to the tibia when the dislocation is located at the level of the patello-trochlear joint. The MRI index of sagittal patellar engagement on the trochlea (IES), described in 2012, does not have this drawback but it does not appear to be reliable: its value depends, in fact, on the flexion of the knee. This flexion, required by the MRI, is variable and is not specified by the radiologist. It is due to the use of an "antenna" that surrounds and lifts the knee. The hypothesis of the study is that it is possible to determine and validate a new IES, in knee extension and therefore reproducible, thanks to the measurement of knee flexion on MRI. The precise value of this flexion can allow a virtual correction of the original IES to obtain, by mathematical calculation, the new IES in virtual extension.
To monitor residual risks in the post-market phase and to ensure continued clinical evaluation of the device safety and performance to ensure that no new or unexpected risks arise when used during multi-ligament knee reconstructions.
To evaluate the effectiveness of the goal development intervention in guiding individual patients through the identification of high quality, specific, measurable, relevant and time-bound goal for treatment.
Comparative evaluation of functional results and survival rate of peroneus longus tendon - PLT and hamstring tendon - HT used for reconstruction of the anterior cruciate ligament.
Selective blockade of the saphenous nerve branches is among the regional anesthesia techniques in knee surgery. In this block, analgesia is provided without motor block and is an essential advantage in terms of early mobilization in the postoperative period. Blockage of motor branches causes a delay in mobilization and increases the risk of falling. The vastus medialis and its medical femoral cutaneous branch are rich in the femoral triangle. Effective postoperative analgesia is provided by a femoral triangle (triangle) blockade. The intermediate femoral cutaneous nerve courses over the sartorius muscle. Anatomically, the femoral triangle follows a separate path. When the femoral triangle and the blockade of the intermediate femoral cutaneous nerve are combined, it is called PSKB block. Parasartorial compartment block (PSKB); is based on the blockade of the branches of the saphenous nerve, the two largest sensory nerves from the femoral nerve to the knee, and is predicted to provide effective postoperative analgesia in knee arthroplasty.
The goal of this study is to pilot test a skills-based virtual reality (VR) for acute orthopedic injury. It will measure the feasibility, signals of improvement, exploratory pain mechanisms, and user experience of an established skills-based program (RelieveVRx) for acute orthopedic injury.
The purpose of this study was to analyze if a low ankle dorsiflexion range is associate with dynamic knee valgus in youth basketball players.
Functional Hop tests and balance measurements are frequently used to decide on returning to sports after lower extremity injuries. Although the athletes show proficiency in these tests and measurements, re-injuries occur when returning to sports. The causes of these re-injuries are mostly functional deficiencies such as inadequate neuromuscular control and stability. In the competition or sports environment, especially in team games, the athlete also shows cognitive performance, such as communication with teammates and following the game, which are included in the game setup, as well as the physical performance. Performing many tasks or performances at the same time divides the focus of attention on the activities performed, and if the person cannot adequately meet the attention demands, the quality of one or more of the tasks performed will deteriorate. As the level of expertise in the sport increases, the athlete tends to manage his posture, balance and movement with automatic postural control and can focus his attention on a new task. The concept of focus of attention has been evaluated from different perspectives over time. If it is examined in terms of direction; It is divided into two as the internal focus of attention, which is used by focusing on body movements during the performance of the person, and the external focus of attention, which is used by focusing on the effect of the movement during the performance of the person. As the investigators planned in this study, a second cognitive task assigned to the participant simultaneously during his or her physical performance acts as an external focus of attention, allowing movement control during performance to be carried out by unconscious or automatic processes. The investigators's aim; It is to examine the balance and functional hop tests that the investigator will apply in athletes by combining them with a simultaneous dual cognitive task that will reflect the field conditions more realistically. In the meantime, investigators think that with the sharing of our results with the literature, it can contribute to both the decision-making processes to return to sports after injury and preventive rehabilitation programs.
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.
