Active clinical trials for "Femoracetabular Impingement"

The purpose of this research is to determine differences in outcomes in patients who receive regional anesthesia (a fascia iliaca block) versus placebo prior to undergoing hip arthroscopy with labral repair and/or debridement and osteoplasty for hip impingement.

Purpose: The aim of this prospective cohort is to evaluate patients before, 6 and 12 months after arthroscopic surgery for FAI and compare the results to people without hip problems. Methods/design: Sixty patients with FAI and 30 persons without hip problems will be included. Pre- and postoperatively, patients will be evaluated by CT-scans. All participants will have their hip flexor and extensor muscle strength assessed and have performed kinetic and kinematic analyses of daily activities with 3D motion capture. Further, self-reported questionnaires on hip related pain, quality of life and sports activities will be collected. Finally, participants will have their daily physical activity monitored with tri-axial accelerometers for five consecutive days. Perspectives: With this prospective cohort study the outcome of arthroscopic treatment of FAI within one year after surgery will be evaluated. If the patients fail to reach reference values one year after surgery, altered surgical procedures or rehabilitation programs to optimize treatment for the patients may be explored in future studies. Further, the investigators expect to perform long-term follow up to evaluate reoperations, conversions to total hip arthroplasty and development of osteoarthritis for the patients surgically treated for FAI.

Following hip arthroscopy for femoroacetabular impingement syndrome (FAIS) decreased hip muscle strength for adduction, extension, flexion, and external rotation including impaired functional performance have been observed. However, no studies are lacking on more demanding muscular and functional parameters such as hip muscle rate of force development and reactive strength index. Information on such muscular properties following hip arthroscopy for FAIS may help guide future planning of post-operative rehabilitation strategies. This is a cross-sectional study with an embedded prospective non-randomized study. The aim of the cross-sectional study is to investigate hip muscle function and functional performance in patients who have undergone hip arthroscopy for FAIS during the preceding 6-30 months. The aim of the prospective non-randomized study is to investigate the effect of a 12-week structured and supervised physiotherapy-led intervention aiming at improving hip muscular function on self-reported hip and groin function including hip muscle function and functional performance. Forty-five subjects from the Capital Region with an age of 18-40, who have undergone a hip arthroscopy for FAIS during the last 6-30 months, will be included in the cross-sectional study. Additionally, all included subjects will be offered to take part in the prospective non-randomized study consisting of 12 weeks of supervised and structured physiotherapy-led treatment. The below measures will be obtained at baseline, and at 12-weeks follow-up if subjects are included in the prospective study. All testing, and supervised physiotherapy-led treatment, will be performed at Hvidovre Hospital: Hip muscle function Single leg jump performance Self-reported hip and groin function Evaluation of return to sport Evaluation of satisfaction regarding usual-care post-operative rehabilitation

To assess the feasibility of using intraoperative ultrasound to evaluate the femoral head formation; to evaluate the improvement of the forming effect using the intraoperative ultrasound combined with c-arm.

Patients included in the HAFAI cohort will be invited for 5 year follow up.

This study will pilot the use of 3D printed models of the hip, for use in pre-operative planning and patient communication to improve clinical outcomes and patient engagement. This method will be implemented in the setting of femoroacetabular impingement (FAI), with the goal of identifying and measuring specific anatomical pathologies and impingement (range of motion) risks, to communicate a pre-operative plan to both the surgical team, and the patient.

Patients are being asked to participate in this study because a previous research MRI of their hips showed that the shape of the head of their thigh bone may indicate FAI of the hip. We have already collected cartilage imaging data and data on how the hip joint moves on people with painful/symptomatic FAI and people with normal hip function. We would now like to compare the motion of the hip joint to those with painful FAI using ultrasound.

Femoroacetabular impingement is an orthopedic condition that is primarily characterized by the presence of anatomic bony abnormalities in the femoral head and/or the acetabulum resulting in an abnormal contact between the two during hip motion, especially in positions of increased hip flexion and rotation, ultimately leading to hip pain. The main study was initiated with the goal of exploring the etiology of FAI in a multidimensional and novel way that addresses the major gaps in literature. Within the main study a 3D motion capture protocol has been designed in line with the latest literature recommendations, which called for more hip ROM specific movements and athlete oriented 3D motion capture protocols that incorporate the spinopelvic complex. While the protocol surely contains movements that have been previously validated and published such as squats and lunges, a unique addition of high velocity soccer kicks and hop- lunges have been included. Such additions elevate the relevancy of the 3D motion analysis protocol, however they also pose questions on how reliable and accurate these additions are. This is especially important a 3D motion analysis has a very subjective component, which is the placement of the skin markers by the clinician. Errors or alteration to markers placement between different sessions or different subjects have been shown to significantly affect the quality of data. Furthermore, not all physical movement can be properly documented using motion analysis. The velocity at which the movement is preformed combined with how complex it is can affect the quality of data collected by the motion analysis system. Also another important component is the uniqueness of the population recruited for the main study. Most studies with highly dynamic motion protocols have been validated and published on adult populations. Thus the investigators cannot use their findings liberally to compare with the adolescent protocol, as differences in patterns of motion between adults and adolescence have been documented. Indeed, a need to test the reliability of the investigators' protocol among their own study groups is highly imperative.

The treatment of femoroacetabular impingement has evolved over the last several years. As the number of arthroscopic hip operations has risen over the last few years, so has the level controversy in regards to the appropriate initial management. There have been many recent advances in clinical diagnosis, advanced imaging techniques, improved indications for surgery and improved arthroscopic techniques which have led to improved clinical outcomes, but the effectiveness of physical therapy remains unknown.

Joint-preserving surgery with arthroscopic techniques of the hip follows detailed radiological assessment including plain radiography of the hips and magnetic resonance arthrography (MRI). The purpose of this study was to compare features on radiography and MRI of the hip before surgery and assess their prognostic value on the outcome after surgery.
