Secondary osteoarthritis of the hip occurs due to a known precipitating cause. In primary or idiopathic osteoarthritis the cause remains unknown although some studies 1,2 have suggested that femoroacetabular impingement (FAI) may be responsible for the pro...

Femoroacetabular Impingement (FAI) arises from morphological abnormalities between the proximal femur and acetabulum. Impingement caused by these morphologic abnormalities induces early degenerative changes in the hip joint. Furthermore, FAI patients complain of severe pain and limited range of motion in the hip, but a guideline for treatment of FAI has not yet been established. Medication, sup...

The purpose of this study was to compare the perioperative complications and traction times in femoroacetabular impingement hip arthroscopy with either a peripheral or central compartment starting point. Sixty patients with femoroacetabular impingement were treated with hip arthroscopy. Thirty patients had a peripheral compartment starting point and 30 had a central compartment starting point. ...

BACKGROUND Femoroacetabular impingement is a frequent cause of hip pain and may lead to secondary osteoarthritis, yet little is known about the molecular events linking mechanical hip impingement and articular cartilage degeneration. The first goal of this study was to quantify the expression of inflammatory cytokine and chemokine, matrix-degrading, and extracellular matrix genes in articular c...

Femoroacetabular impingement causes pain in the hip in young adults and may predispose to the development of osteoarthritis. Genetic factors are important in the aetiology of osteoarthritis of the hip and may have a role in that of femoroacetabular impingement. We compared 96 siblings of 64 patients treated for primary impingement with a spouse control group of 77 individuals. All the subjects ...

INTRODUCTION: Rotational acetabular osteotomy (RAO) has been recognized as an useful procedure, especially for early stage of osteoarthritis of the hip, with satisfactory intermediate and long-term results. In RAO, it is important to rotate the acetabular roof sufficiently, contributing to improvement of the acetabular roof coverage. On the other hand, femoroacetabular impingement due to acetab...

Femoroacetabular impingement, also known as hip impingement, is the abutment of the acetabular rim and the proximal femur. Hip impingement is increasingly recognized as a common etiology of hip pain in athletes, adolescents, and adults. It injures the labrum and articular cartilage, and can lead to osteoarthritis of the hip if left untreated. Patients with hip impingement often report anterolat...

This paper describes a methodology for the simulation of musculoskeletal disorders. Our clinical study is related to osteoarthritis of the hip, a pathogenesis possibly due to impingements. These bone collisions lead to abnormal joint mechanics which is characterized by contact pressure and stress distribution upon the joint cartilages. The proposed methodology combines different approaches from...

To investigate the correlation between femoroacetabular cartilage thickness and lateral acetabular coverage in patients undergoing hip arthroscopy for a variety of indications. Articular cartilage at the hip is hypothesized to undergo adaptive change secondary to unique patterns of pathomechanical loading which results in a direct relationship between acetabular coverage and femoroacetabular ca...

BACKGROUND Developmental hip disorders (DHDs), eg, developmental dysplasia of the hip, slipped capitis femoris epiphysis, and femoroacetabular impingement, can be considered morphology variants of the normal hip. The femoroacetabular morphology of DHD is believed to induce osteoarthritis (OA) through local cumulative mechanical overload acting on genetically controlled patterning systems and su...
