Filter by:It has been shown that especially adolescent female athletes have a very high risk of injury compared to males. Gender differences (anatomical, biomechanical, neuromuscular and hormonal differences) contribute to the increased risk of injury. Basketball, one of the sports preferred by adolescent girls, brings with it high risks of injury due to the high participation rate among team sports. The occurrence of lower extremity injuries such as anterior cruciate ligament injuries and patellofemoral pain during dynamic activities (e.g., landing, running, etc.) has been associated with dynamic knee valgus, a pattern of lower extremity malalignment. At the same time, weakness of the core muscles and inadequate ankle dorsiflexion joint range of motion also contribute to the injury. The aim of this study is to examine the correlation between landing biomechanics, core endurance and ankle dorsiflexion angle in adolescent female basketball players with dynamic knee valgus.
The purpose of the study is to collect post-market clinical follow-up data, which is needed to confirm the safety and performance of the JuggerKnot device and meet existing EU regulatory requirements.
This research aims to assess physiotherapy utilization in the treatment of patients with an anterior-cruciate ligament knee injury, when delivered before their surgery (prehab), and its potential effects on absence from work, and patients global health consumptions (before and after the surgery).
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.
Noncontact knee injuries are a concern in netball. As such, it is important to devise appropriate injury prevention programs that players will complete to reduce the risk of injury. Previous research suggests that the most common situation of noncontact knee injury in netball involves a stiff landing or apparent knee valgus collapse, trunk rotation, and lateral flexion. Therefore, the aim of this study is to investigate the effect of a neuromuscular training program on biomechanical risk factors during a netball-specific landing.
A phase I/II clinical trial (first in human) to assess the effectiveness and safety of the treatment of cartilage injury with a tissue engineering construct composed of stromal vascular fraction collected from the synovial membrane and infrapatellar fat of the injured knee, submitted to enzymatic processing in a single surgical time, associated with a collagen scaffold. The primary outcomes will be assessed by 3T magnetic resonance imaging, quality of life and knee function questionnaires, in addition to perioperative and post-operative complications. Secondary outcomes will be evaluated by measuring the health resources used to ensure compatibility, reproducibility and generalizability of the technique. The authors believe that adverse events will be similar to current surgical procedures and that there will be an improvement in knee function scores and quality of life of patients undergoing the procedure.
The overall purpose of this study is to quantify the effect and retention of one-week training of falling techniques on landing biomechanics associated with anterior cruciate ligament (ACL) loading compared to soft-landing techniques in young recreational athletes. The secondary purpose is to assess the safety of the training program. Aim 1: To quantify the effect of one-week training of falling techniques on landing biomechanics during forward, lateral, vertical, and diagonal landings compared to soft-landing techniques. We hypothesize that falling techniques will result in increased knee flexion angles and decreased landing forces, knee abduction and internal rotation angles, and knee moments for all landing directions compared to soft-landing techniques immediately after the training. Aim 2: To assess the retention effects of the falling techniques on landing biomechanics compared to soft landings. We hypothesize that the effects of falling techniques on ACL loading variables will be more highly retained compared to soft-landing techniques two weeks after the training. Aim 3: To identify the safety of the training program. We hypothesize that participants can complete the training without suffering minor, moderate, or major injuries, while occasional minor bruises might be observed.
Multi-ligament knee injuries (MLKI) are devastating injuries. They are defined as injuries to at least two of the four major ligaments in the knee: anterior cruciate ligament, posterior cruciate ligament, lateral collateral ligament (and posterolateral corner) and medial collateral ligament (and posteromedial corner). These injuries are commonly classified using the Schenck classification system. The incidence of these injuries has been reported to be around 0.02-0.20% of all orthopaedic injuries. However, this is likely to be an underestimation due to spontaneous knee reduction and missed injuries. The immediate management of these injuries is crucial in identifying and treating any vascular and nerve injury. The literature has shown poor outcome and residual instability in those who were treated non-operatively. However, the optimal surgical treatment for these injuries is not known, with differences in opinion amongst treating clinicians. There are controversies in the timing of surgery (early versus delayed), single-staged or two-staged procedures and whether the damaged ligaments should be repaired or reconstructed
In vivo knee kinematics will be assessed for 20 subjects that have been implanted with either a MicroPort Medial Pivot or DePuy Attune posterior cruciate retaining (PCR) total knee arthroplasty (TKA) by Dr. Russell Nevins of Nevada Orthopedic & Spine Center [this is the location from which participants will be recruited].
This study aims to benchmark the performance of an iOS application against the Berg Balance Scale (BBS), which is the most commonly used assessment tool by clinicians for measuring balance across the continuum from acute care to community-based care. An iPhone will be tied around the waist of the participant and concurrent measurements will be taken for five of the fourteen stances which comprise the BBS.
