The etiology of degenerative joint disease of the hip remains unsolved. A precursor for some patients, especially younger ones, may be hip impingement. Repetitive microtrauma at maximal flexion can cause chronic pain from the abutment at the femoral head-neck junction caused by an abnormal offset. Chronic impingement from an aspherical head can lead to degenerative labral tears and acetabular c...

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...

Young adults with hip pain secondary to femoroacetabular impingement (FAI) are rapidly being recognised as an important cohort of orthopaedic patients. Interest in FAI has intensified over the last decade since its recognition as a precursor to arthritis of the hip and the number of publications related to the topic has increased exponentially in the last decade. Although not all patients with ...

Background: Femoroacetabular impingement (FAI) syndrome, or hip impingement, is a musculoskeletal condition affecting the joint. It involves motion- position-related pain originating from an abnormal, premature contact between femoral head-neck junction (femur) and acetabular rim (rim around socket). Cumulative repetitive mechanical overloads at joint appear to contribute development of FAI. Ho...

Computer navigation of total hip arthroplasty and computer simulation of hip motions based on collision detection were both introduced more than ten years ago. Neither of these promising technologies has achieved its full potential to improve patient outcomes. Combining these two technologies allows the individual strengths of each to more easily demonstrate hip kinematics in a clinically usefu...

CONTEXT Several risk factors may cause femoroacetabular impingement (FAI). Knowledge of causation would identify patients for early intervention, prior to the development of painful intra-articular damage. DATA SOURCES PubMed, MEDLINE, EMBASE, and related article reference lists were screened for relevant studies published between January 2000 and December 2013. STUDY SELECTION Inclusion cr...

PURPOSE To determine whether femoroacetabular impingement (FAI) is associated with hip instability. METHODS A systematic search examining FAI and hip instability was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Clinical and basic science studies were included. Instability had to be documented with either a clinical or imaging e...

PURPOSE The purpose of this study was to compare the outcomes of arthroscopic labral debridement with those of labral refixation. METHODS We reviewed patients who underwent labral debridement during a period before the development of labral repair techniques. Patients with labral tears deemed repairable with our current arthroscopic technique were compared with patients who underwent labral r...
