Femoroacetabular impingment

CONTEXT: Six-months is the expected timeframe to return to sport (RTS) after hip arthroscopy for femoroacetabular impingement syndrome (FAIS). OBJECTIVE: The primary aims of this study were to (1) report the RTS rate of physically active individuals six-months after arthroscopic surgery for FAIS, and (2) compare the self-reported hip function between those who were able to RTS versus those who had not. DESIGN: cohort study. SETTING: XXX...

PURPOSE: The most commonly used parameter for defining cam-type femoroacetabular impingement(FAI) has been the alpha angle. The purpose of this study was to determine if patient-reported outcomes 5 years following hip arthroscopy for FAI were associated with postoperative alpha angle. We hypothesized that patient-reported outcomes would not be influenced by postoperative alpha angle in patients with FAI. METHODS: 230 patients had primary hip arthroscopy for FAI and chondrolabral dysfunction...

Objective The International Cartilage Repair Society classification is the one mainly used to define chondral defects. However, this classification does not include delamination. The objective of the study is to describe the characteristics of this lesion to better explain its classification in the context of chondral lesions of the hip. Design We performed a retrospective analysis of 613 patients who underwent hip arthroscopy. In this group, the incidence, localization, histological characteristics, and association to femoroacetabular impingement as well as to other intraarticular lesions of acetabular delamination (AD) were analyzed...

PURPOSE: The purpose of this study was to determine whether patients diagnosed with femoroacetabular impingement (FAI) syndrome have prolonged braking times compared with age- and gender-matched controls and how long after surgery braking times return to preoperative baseline. METHODS: Fifty-nine patients undergoing arthroscopic hip surgery for FAI and 59 age- and gender-matched controls without FAI were enrolled in a prospective comparative study between September 2015 and October 2016...

The existing literature on subjects with femoroacetabular impingement syndrome undergoing arthroscopic or open hip preservation surgery reveals that outcome reporting is heterogeneous. There is significant inconsistency in patient-reported outcome scores collected, symptoms and complaints assessed, clinical signs evaluated, and pre- and postoperative imaging metrics measured.

OBJECTIVE: Clinicians use the flexion, adduction, and internal rotation (FADIR) test in the diagnosis of femoroacetabular impingement (FAI). However, the diagnostic utility of this test remains unclear. The purpose of this review was to determine the utility of the FADIR test in diagnosing FAI. DATA SOURCES: MEDLINE, EMBASE, and PubMed were searched using relevant key terms and study screening was performed in duplicate. Patient demographics, diagnostic imaging, and summary measures (eg sensitivity, specificity, etc...

PURPOSE: This study was designed to (1) evaluate the clinical outcomes after arthroscopic subspinal decompression in patients with hip impingement symptoms and low AIIS, and to (2) assess the presence of low anterior inferior iliac spine on the pre-operative radiographs of patients with established subspinal impingement diagnosed intra-operatively. METHODS: Retrospective analysis of patients who underwent arthroscopic subspinal decompression has been performed. The indications for surgery were femoroacetabular impingement (FAI), or subspinal impingement...

Study Design A pilot double-blind randomized controlled trial (RCT). Background The effectiveness of physical therapy for femoroacetabular impingement syndrome (FAIS) is unknown. Objectives To determine the feasibility of an RCT investigating the effectiveness of a physical therapy intervention for FAIS. Methods Participants were 17 women and 7 men (mean ± SD age, 37 ± 8 years; body mass index, 25.4 ± 3.4 kg/m2 ) with FAIS who received physical therapy interventions provided over 12 weeks. The FAIS-specific physical therapy group received personalized progressive strengthening and functional retraining...

Femoroacetabular impingement (FAI) is the abnormal osseous contact between the femur (cam impingement) and/or acetabular rim (pincer impingement) during end-range hip motions. This special issue on FAI aims at closing some of the gaps between clinical practice and research findings, important for all health professions treating patients with hip pain. This special issue will explore several aspects of FAI syndrome. Specifically, it will provide clinicians with a greater understanding of the etiology and prevalence of hip morphology seen in FAI syndrome, and its relationship with hip range of motion, muscle strength, and hip osteoarthritis (OA)...

Synopsis The number of hip arthroscopies for the management of femoroacetabular impingement syndrome and other hip intra-articular conditions has grown exponentially in the last decade. Postoperative rehabilitation is part of the treatment algorithm, although there is a lack of high-quality studies on the efficacy of both surgery and postoperative rehabilitation programs. It is known that impairments can be present up to 2 years after hip arthroscopy, with individuals exhibiting reduced function and quality of life when compared to those of similar age, highlighting a need to improve postoperative care...

Study Design Study protocol for a randomized controlled trial and a prospective cohort. Background The number of arthroscopic surgical procedures for patients with femoroacetabular impingement syndrome (FAIS) has significantly increased worldwide, but high-quality evidence of the effect of such interventions is lacking. Objectives The primary objective will be to determine the efficacy of hip arthroscopic procedures compared to sham surgery on patient-reported outcomes for patients with FAIS (HIP ARThroscopy International [HIPARTI] Study)...

BACKGROUND: Femoroacetabular impingement (FAI) syndrome is one source of hip pain that can limit sport participation among athletes. OBJECTIVE: To summarise the return to sport (RTS) rate for athletes after surgery for FAI syndrome. METHODS: A computer-assisted search of MEDLINE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL) and EMBASE databases was performed using keywords related to RTS and RTS at preinjury level (RTSPRE ) of competition for FAI syndrome...

Sheep hips have a natural non-spherical head similar to a cam-type deformity in human beings. By performing an intertrochanteric varus osteotomy, cam-type femoroacetabular impingement can be induced experimentally. In sheep, the aspherical portion is located superiorly - exactly matching the region where the superior retinacular vessels enter the femoral head-neck junction in human beings. In order to fully exploit the potential of this experimental FAI model, a safe osteochondroplasty of the superior asphericity would need to be done without the risk of avascular necrosis...

PURPOSE: Femoroacetabular impingement (FAI) is a clinical entity of the hip causing derangements in range of motion, pain, gait, and function. Computer-assisted modeling and clinical studies suggest that patients with FAI have increased capsular thickness compared to those without.A retrospective chart review was performed to assess relationships between capsular thickness, hip range of motion, and demographic factors in patients with FAI. METHODS: Local Research Ethics Board approval was obtained to extract electronic medical records for 188 patients at a single institution who had undergone hip arthroscopy...

PURPOSE: Although the arthroscopic management of femoroacetabular impingement (FAI) is increasing, severe complications have been reported due to traction. We developed an arthroscopic technique based on an initial capsulotomy and a minimal traction approach. The main purpose of this study was to analyze the clinical outcomes of FAI treatment using this technique after at least two years of follow-up. METHODS: Forty-seven consecutive patients underwent surgery for FAI...

This is a retrospective review of two adult siblings with osteogenesis imperfecta (OI) type III (according to Sillence classification), who sustained a spontaneous femoral neck fracture and subsequent nonunion. The diagnosis of OI in these two patients was made based on clinical, radiological and genetic findings. The fracture was most likely caused by femoroacetabular impingement secondary to OI induced acetabular protrusio. A valgus osteotomy according to Pauwels'principles and fixation of the osteotomy and nonunion with a locking plate resulted in healing despite compromised bone quality and limited bone stock...

Purpose: Femoroacetabular impingement (FAI) is considered an important cause of early degenerative arthritis development. Although three-dimensional (3D) imaging such as computed tomography (CT) and magnetic resonance imaging are considered precise imaging modalities for 3D morphology of FAI, they are associated with several limitations when used in out-patient clinics. The paucity of FAI morphologic data in Koreans makes it difficult to select the most effective radiographical method when screening for general orthopedic problems...

INTRODUCTION: The restoration of range of motion after surgery in patients with femoroacetabular impingement syndrome is considered an important factor that improves clinical outcomes and determines the quality of life of patients, especially in the Asian population. METHODS: Arthroscopic femoroplasty was done in 109 Asian patients with cam impingement. The patients were retrospectively evaluated using range of motion and clinical outcomes (Harris Hip Score [HHS], visual analog scale score, Hip Outcome Score-Activity of Daily Living, and Hip Outcome Score-Sports subscales) between preoperative and postoperative conditions, with a follow-up period of >2 years...

BACKGROUND: Impingement resulting in soft tissue damage has been observed in hips with abnormal morphologies. Geometric parameterisation can be used to automatically generate a range of bone geometries for use in computational models, including femurs with cam deformity on the femoral neck. METHODS: This study verified patient-specific parametric finite element models of 20 patients with cam deformity (10 female, 10 male) through comparison to their patient-specific segmentation-based equivalents...

Study Design Cross-sectional study. Background Visual rating of movement pattern in patients with femoroacetabular impingement (FAI) syndrome is of interest because poor control of dynamic hip motion is frequently noted. Objectives To evaluate intra- and inter-rater agreement among physical therapists with different clinical experience, in performing visual rating of movement pattern quality of patients with FAI syndrome using a semiquantitative scale. Methods A video camera was used to record the performance of 34 patients with FAI syndrome performing single-limb standing, squat, frontal lunge, hop lunge, bridge and plank...
