Active clinical trials for "Femoracetabular Impingement"

The diagnostic gold standard to differentiate FAI (femural acetabular impingement) from other muscular-tendinous pathologies is, actually, the injection of intra-articular anesthetic (lidocaine), with a pre- and post- evaluation of pain scale. If, after injection, the pain disappears, the pain is probably due to an articular problem (FAI). This kind of differential diagnosis test has a sensibility of 100% and a specificity of 81%. C-terminal telopeptide of type II collagen (CTXII) as cartilage degradation index, could be a marker, simply detectable, to assess the healthy of the cartilage status and could be measured in serum and urine.

Femoroacetabular hip impingement syndrome is a newly recognized cause of early arthritis of the hip. In this condition a variation in the shape of the upper thigh bone causes it to repeatedly come in contact with the hip socket leading to cartilage damage and arthritis. The purpose of this study is to investigate whether patients without hip pain have variations at the hip joint such as those seen in hip impingement syndrome.

In order to investigate the relationship between the iliac joint capsular muscle and the development of the hip joint, this study used ultrasound Doppler to measure the anatomical circumference of the iliac joint capsular muscle to explore the relationship

To explore the changes of the muscles around the hip joint after hip arthroscopy for patients with femoral acetabular impingement syndrome.

The purpose of this study was to investigate the change in muscle volume around the hip in patients with unilateral femoro-acetabular impingement (FAI) after arthroscopy.

The goal of this observational study is to describe the radiographic and kinematic features in patients with femoroacetabular impingement syndrome (FAI). The main questions it aims to answer are: Is structural knee abnormalities associated with knee pain symptoms in FAI patients? Does FAI patients with knee pain demonstrate unique kinematic characteristics？ Participants will receive routine preoperative radiographic examinations, which include ipsilateral knee MRI for the purpose of femoral version measurement. Participants will also receive markerless motion capture analysis. Researchers will compare preoperative radiographic and kinematic features based on knee pain status, which is routinely collected as part of clinical investigation procedures.

The primary objective of this study is to investigate factors hypothesized to influence the prevalence of hip pathomorphology (femoroacetabular impingement, dysplasia) in young adults. To complete this objective, we will quantify the prevalence of radiographic measures indicative of hip pathomorphology in collegiate athletes and age-matched controls. This data will allow us to test our main hypothesis, that the prevalence of hip pathomorphology is higher in collegiate athletes than age-matched controls. To further elucidate the factors which may increase the prevalence of hip pathomorphology, we will correlate the radiographic measures to sport involvement history, hip function and demographics, as collected by means of a questionnaire. The secondary objective of this study is to determine if physical exams (range of motion, impingement test) could be used to screen for radiographic measures of hip pathomorphology in athletes and age-matched controls. To complete this objective, we will correlate range physical exam results to the radiographic measures and determine each exam's sensitivity and specificity to detect abnormal morphology.

Femoroacetabular impingement (FAI) is a clinical problem in which abnormal contact occurs between the thighbone and the hip socket. In intensive, mostly still young, male athletes, this problem seems to be related to a bony deformity on the head of this thighbone, a so-called CAM. FAI itself gives rise to pain symptoms, but in time can even lead to premature osteoarthritis. However, the cause of a CAM deformity itself, nor how FAI then arises, is insufficiently known. In view of FAI prevention and its better treatment, this project thus tries to better understand the underlying mechanisms. For this purpose, we will combine detailed biomechanical evaluations of specific movement patterns with advanced medical imaging and state of the art clinical evaluations to longitudinally follow up a group with a known high risk of developing a CAM deformity, being young male elite soccer players. Findings within this study will be additionally compared with similar analyses performed in patients with FAI. This research aims to thus form a basis to define novel (sports-specific) training schemes for the prevention of FAI, but also to define the actual treatment and rehabilitation plans in more patient-specific and a better-informed way.

To study the effect of arthroscopy on the treatment of hip diseases and to evaluate the regularity and treatment of hip joint diseases.

Femoro-acetabular impingement (FAI) is a known cause of hip pain and possibly a major cause of adult hip osteoarthritis. The relationship between cam-type FAI deformity characteristics and joint degradation to better identify 'at-risk' patients requiring corrective surgery will be scrutinized to gain a better understanding of the condition's natural history. The influence of certain morphologies (e.g. size and location of the deformity) will be analyzed to determine if this leads to aberrant loading of regions of the cartilage and subchondral bone, resulting in cartilage damage and joint degradation. Additionally, this research will determine if changes in the subchondral bone precede cartilage degeneration. The methodology for establishing the morphology/cartilage degeneration relationship includes Magnetic Resonance Image (MRI) analysis, three-dimensional motion analysis and computer simulation/finite element analysis. The outcomes of this research may lead to a reduction in total hip replacement cases by as much as 70%, saving many Canadians from a painful and debilitating condition and reducing costs to the Canadian health care system by as much as $290 million annually.
